Cement plant emissions significantly impact the environment by releasing enormous quantities of carbon dioxide (approximately 8% globally), particulate matter, and dust, causing air pollution and climate change, and harming public health and ecosystems. To address this, emissions and waste are being utilized in new building materials through technologies such as carbon capture for use in other products, the development of low-carbon building materials, and the recycling of production waste as additives, thus reducing the environmental footprint and turning the challenge into an opportunity. To reduce these gas emissions and to study alternatives for them, we will address in this work an actual experience of the cement factory located in the state of M'Sila, Algeria, and present the proposed solutions for that.

This research investigates the use of waste glass powder as a partial replacement in cementitious materials to promote sustainable construction in Algeria. Currently, most recycled materials in Algeria are predominantly used for roadworks or backfilling, while clinker production the main component of cement remains a major source of CO2 emissions contributing to environmental degradation. Waste glass powder, possessing pozzolanic properties, offers a promising alternative by partially replacing cement or fine aggregates in concrete mixes. Experimental results demonstrate that using glass powder at replacement levels of around 10-15% improves the compressive strength and durability of concrete while reducing the environmental footprint of cement production. Above these levels, efficiency declines due to limited pozzolanic reaction. Incorporating glass powder not only diverts industrial waste from landfills but also enhances mechanical performance and sustainability of construction materials. This approach represents a viable strategy for reducing carbon emissions and optimizing resource use in the Algerian construction industry, with potential applications in similar regions worldwide. This study contributes valuable insights for advancing greener materials and sustainable infrastructure development by harnessing recycled glass powder within cementitious systems.

Waste management first appears to be a question of organization and optimization of already known techniques, whose environmental effects are apparently under control. It thus presents itself less as a major environmental issue than as an economic and management issue. The importance of renewable energy, more specifically through the energy recovery of incineration, clearly appears as an interesting alternative. In this study, we focus on incineration, considered efficient. This incineration not only stabilizes waste while reducing its pollutant load, but also produces thermal and electrical energy; renewable energy that can be used in various domestic applications. The objective of this paper is to present a study on the phenomenon of incineration taken from a bibliographic collection.

In construction, concrete strength is traditionally evaluated using destructive compression tests on concrete cubes. However, when doubts arise regarding the conformity of these results to standards, or when destructive testing is impractical, non-destructive testing (NDT) methods provide a valuable alternative. This study investigates the effects of incorporating locally sourced waste mineral fillers glass powder (GP), marble powder (MP), and silica fume (SF) into ordinary concrete mixtures. Five concrete formulations with varying proportions of these fillers, alongside a fixed 1.5% superplasticizer dosage, were prepared and evaluated. The study assessed hardened state properties, including compressive strength. Additionally, NDT techniques ultrasonic pulse velocity and rebound hammer tests were employed to estimate compressive strength without damaging the samples. Robust mathematical models correlating compressive strength (Rc) with ultrasonic velocity (V) and rebound hammer number (Is) were developed and validated using statistical measures such as the coefficient of determination (R²) and mean prediction error. The findings indicate that incorporating sustainable waste mineral fillers can effectively enhance concrete performance while enabling reliable estimation of its strength through non-destructive methods.

This research includes an experimental study to study the effect of high temperatures on the mechanical and physical properties of concretes formulated with adjuvants. The concrete was exposed to three high temperature levels (200, 400 and 600) ° C with a temperature rise of 10 °C /min, without any load imposed during heating. One type of adjuvant was used. The mechanical properties of the concrete have been studied at different high temperatures, including: compressive strength, flexural tensile strength and mass loss. The results showed a reduction in the properties studied by different rates for adjuvant and for each temperature; the decrease was very limited at a temperature up to (200°C) but was clear between (400-600°C).

In the pursuit of sustainable development and addressing the growing issue of inert waste, this work explores the potential of using recycled sanitary ceramic as a partial replacement for natural sand in the production of ordinary concrete. The study aims to evaluate the impact of exposure to acidic environments, represented by sulfuric acid (H₂SO₄) and hydrochloric acid (HCl) solutions, on the performance of this modified concrete. The results show that the chemical reaction between the acids and the calcium compounds present in the concrete leads to a significant decrease in its fundamental properties, such as mass, volume, and compressive strength. This continuous degradation, in the presence of acids, indicates potential challenges when using this type of concrete in environments with an acidic nature. Keywords: Concrete, dune sand, ceramic waste sand, chemical degradation.

Concrete is a versatile and essential building material, comprising two fundamental components: aggregate and paste. The aggregate, typically consisting of sand, gravel, or crushed stone, provides structural strength, while the paste—made from binders like Portland cement (with or without additives), water, and air-acts as a binding agent. Through the chemical reaction of hydration, this paste hardens, transforming the mixture into a robust, rock-like substance known as concrete. To enhance specific properties of fresh or hardened concrete, admixtures and additives are often utilized. In our practical application, we focus on incorporating marble powder as a distinct cement additive. This locally sourced, recycled material is not only readily available and cost-effective but also easily processed. Our goal is to unlock the potential of mineral powders, such as marble powder, by integrating them into high-quality concretes, thereby adding value to these materials.

The valorization of glass waste in concrete is achieved by using glass in the form of fine or coarse aggregate, or as a partial substitute for powdered cement. Crushed glass can be used as a sand replacement aggregate or as pozzolanic filler, with potential advantages such as improving certain concrete properties (rheology, deformability) and reducing CO2 emissions. However, excessive use can negatively affect mechanical strength. In this study, we will conduct a literature review on various completed works that discuss this topic from the perspective of the environment and mechanical properties.

The use of mining waste in mortars is a promising practice for improving the performance and durability of construction materials, while reducing the environmental impact of the construction industry. However, accurate characterization of the waste and a thorough study of its effects on mortar properties are required to ensure optimal results. Fibers in concrete and mortar play a crucial role in improving their performance, including controlling cracking, increasing strength, and reducing permeability. They act as internal reinforcement, compensating for potential weaknesses in the material. In this study, we will conduct a literature review on various completed works that discuss this topic from the perspective of the environment and mechanical properties.

Paste and self-placing mortar (MAP ), an essential compound in making concrete, is also the most important bond in construction. It is made from valley sand, but it has a negative impact on the environment on the one hand, and on the other hand, it affects significant material costs, in addition to the fear of the lack of Alluvial sand(SA). All of these data encourage us to use river sand and dune sand, and to mix the two different types. In our research, we are studying the effect of including dune sand (SD)and river sand(SR) to replace valley sand in improving and creating the best rheological properties: The mini slump flow, V-funnel flow time and the viscosity measurement , They must to have better mechanical performance. The results indicated that all MAP mixtures containing river sands including SA (control) had acceptable rheological properties considering.

Achieving environmentally friendly compounds with high mechanical resistance, lower density, and high thermal resistance is a topic of research for most of those interested in this field. Geopolymers are three-dimensional amorphous materials made of aluminosilicates in a normal environment or at high temperatures through alkaline activation of aluminosilicate materials. This activation, along with the addition of a chemical foaming agent (aluminum powder, hydrogen peroxide, sodium oleate...) led to the synthesis of inorganic foam. Geopolymer foams are high temperature resistant materials characterized by mechanical and chemical stability and low post-foaming shrinkage. Pore size is directly related to changing the concentration of the foaming agent, and studies have shown that, by tracking CT images, up to 24% open porosity can be achieved without significantly affecting other properties. In addition to geopolymers enjoying these advantages, we find some studies interested in obtaining other advantages, including adding another factor that...Thermal properties of geopolymer concrete (GPC) are enhanced by adding phase change material (PCM) capsules. Thermal and structural tests were conducted to investigate the effects of capsules on the properties of produced GPC. The produced thermally enhanced GPC can reduce heat transmission too indoors in the hot climates and its compressive strength is acceptable for non- loadbearing wall components.

The search for an alternative to cement has become an environmental and strategic necessity to reduce the effects of global warming and preserve the energy capacity of energy-importing and energy-exporting countries alike. Geopolymer materials are classified as green materials and may be the alternative solution proposed at the present time due to their advantages. The results of research and studies have shown that these geopolymer materials possess superior mechanical and physical properties, including high early strength, good chemical resistance, low shrinkage, and good thermal resistance. The rise in temperatures in recent years and the global warming scenario has led to an increase in demand for heat-insulating materials, especially in the construction sector. This review includes, based on previous research, previous knowledge of more about the basics of these geopolymer materials the raw materials that go into preparing these compounds and the factors affecting their properties. The good thermal performance of these compounds is considered important and vital to exploit in the production of efficient insulating materials, and it may be a sustainable solution in re- exploiting mineral waste in order to preserve natural resources.

And then treated in fresh fresh water, salt solution where the salt is 5% sodium chloride and finally in MgSO4 solution at 5% concentration for 7, 14 and 28 days, then mechanical tests are performed when the test used in this research is compressive strength and porosity. It was observed that there were differences in compressive strength when immersed in different solvents. Samples immersed in water have higher resistance than those immersed in sodium chloride MgSO4 solution and increase with immersion time. The results show that the addition of glass powder improves the flow of concrete, also it further consolidates the cementitious matrix which makes it difficult for aggressive compounds to penetrate into the concrete.

Recent studies recognize a great interest in preserving the environment and sustainable development by reducing the carbon dioxide generated from the cement industry by replacing it with environmentally friendly materials. This could be achieved by replacing a part of cement with mineral addition during concrete mixing. In recent years, the incorporation of metakaolin (MK) in building materials is growing and the compressive strength of cement-based composites is maximized with a 20% content of MK.

In recent years, due to the modern lifestyle, industrial and technological progress has led to a significant increase in the quantity and quality of waste. Waste accumulation problem every year is all over the world. The use of materials from waste in buildings compensates for the lack of natural resources, solves the problem of waste management and provides an alternative technique for protection of the environment. In Algeria, the Ministry of Environment demonstrated that the recycling market is estimated at 23 billion Algerian dinars (about 260 million USD). In this vision, policy makers aspire to establish a real industry for recovery and recycling of waste through the development of several sectors such as plastics, aluminum paper and cardboard, metals, glass, wood, etc. This review assesses Aluminum waste (Al) in concrete as a substitute for aggregates and cement. The physical, mechanical and environmental properties of the materials obtained by substitution of raw materials by Al waste were examined and compared to reference materials. Mining waste in cementitious materials offers good compressive strengths, while the porosity of the concrete and/or mortar is a factor influencing its toxicity.

The present study aims primarily to investigate the possibility of assessing the physico-mechanical behavior of concrete incorporating marble waste or marble powder as a partial replacement for cement using destructive and non-destructive testing methods. Indeed, in this work, cement was partially replaced with marble powder at six different substitution levels, i.e. 5, 10, 15, 20, 25 and 30% by weight, with 1.5% adjuvant (super plasticizer) for each mixture. The samples prepared were then analyzed. In addition, the physico-mechanical properties, in the fresh and hardened states, water-to-cement ratio, absorption and compressive strengths of the concrete samples were examined as well. Moreover, the compressive strength of concrete was assessed through non-destructive testing methods such as the ultrasonic pulse velocity and rebound hammer. Likewise, the relationship between the ultrasound velocity and compressive strength of concrete were also estimated after 3, 7, 28 and 90 days of curing. The findings of the study indicated that, at early age of curing, the values of the compressive strength and ultrasonic pulse velocity were quite small for all replacement levels, of cement with marble powder, between 15 and 30%. Nevertheless, when the curing period was increased, the compressive strength and ultrasonic pulse velocity of all the samples went up as well. In the end, a linear relationship was observed between the ultrasonic pulse velocity and compressive strength for all substitution levels of cement with marble powder.

The development of new building materials is the problem of time, where researchers trying to find inexpensive equipment adapted in line with the field of use, the use of additional materials in the cement industry continues to increase and is often called on these metal additions materials we get from natural sources or remnants of industrial materials. In addition, the use leads to a reduction of clinker consumption and contribute to solving environmental problems in a simple and economical manner. The main objective of this experimental work is to study the proportion of powdered glass and marble dust on the physical and mechanical behavior of the composite cement and mortar. The obtained results the results obtained show that the partial compensation of glass cement powder 10% give the best values.

The search for a cheaper binder using natural resources and industrial waste has become a major concern in the manufacture of cement. According to the literature, researchers have found that glass and marble waste in the form of powder can be introduced into cement to obtain a cheaper and less polluting cement. In this study, we attempted to determine the strength of concrete containing glass powder and marble powder by partially replacing cement in concrete. Cement substitution by these mineral additions in the range of 5% to 10%. This approach is based on the properties of the material and its effect on the physical and mechanical properties of concrete. Several parameters are considered, namely: the effect of filler, the effect of the adjuvant and the ratio W / C, to lead, to the making of a concrete based on local materials characterized by good strength, porosity minimum and acceptable durability.

This study aims to valorize mineral residues as an addition to cementitious matrix building materials. It is part of a sustainable development approach. The use of recovered and recyclable industrial residues as a partial replacement of Portland cement in concrete reduces greenhouse gas emissions and results in the manufacture of concrete with less environmental impact. The use of crushed glass powder to replace clinker presents a promising way to recover and recycle waste. By taking advantage of different experimental techniques, particular attention is given to the behavior of the finely ground glass powder associated with Portland cement. Cement replacement by glass powder in the range 5% to 10%. This approach is based on the material properties and its effect on the properties of hardened concrete strength porosity, several parameters are considered, namely: The effect of filler, the effect of adjuvant and W/C, porosity, leading to the production of concrete local materials characterized by good strength, porosity and minimum acceptable durability.
