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. While the mixtures containing river sands(SR) showed higher mechanical properties than the control (SA).

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.

This study examines the mechanical effects of the addition of transparent glass in the form of waste glass powder on the mechanical properties of concrete in aggressive environments.Glass is used as an additive after conversion to fine powder and mixed with cement at 0% , 5% and 10% For the construction of concrete with additives and then poured into molds. 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.

The purpose of this study is to recover mineral residues as an additive in cement-based building materials. It is part of a sustainable development approach. The use of recovered and recyclable industrial residues in partial replacement of Portland cement reduces greenhouse gas emissions and results in the manufacture of cement with a lower environmental impact. Using various experimental techniques, particular attention is paid to the behaviour of the ceramic powder finely crushed and chemically activated associated with Portland cement. This study confirms the improvement in the physicochemical and mechanical properties of cements with the addition of ceramic powder, which augurs well for its use as a cement

This paper investigated the effects of brick dust and metal fiber on the mechanical and physical properties of cement mortars exposed to high temperatures experimentally and statistically. For this purpose, the mixes containing marble dust (0%, 5%, and 10% by volume) and metal fiber (0 kg/m3, 1 kg/m, 2 kg/m3, 5 kg/m3) were prepared. The cement mortars' compressive strength and porosity value were determined after exposure to high temperatures (300, 500, and 700 C). The percentage of brick dust, amount of metal fiber, and degree of temperature were changed to explore their effects on specimens' compressive strength and porosity values. Finally, experimental findings were compared with statistical results, and a good agreement between them was achieved.

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. This study is concerned with the different results obtained among the various literatures regarding mechanical resistance of local kaolin at various temperatures (400 – 900 °C) and durations (2, 3 and 4 h) to produce MK with a high pozzolanic activity.

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 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.
