The decarbonization of concrete structures sector is a priority due to the world climate. Since Portland cement responsible for approximately 7% anthropogenic emissions worldwide, it decisive partially replace by products with lower environmental impact. Fly ash has become highly demanded, its proven advantages, however, announced end developed countries. purpose this research develop and chara...

Abstract The use of nano clay to improve the qualities construction materials and engineering applications has attracted a lot discussion in recent years. This review article summarizes influence as cement substitute supplement on performance conventional high-performance concrete. addition high concrete revealed an increase compressive flexural strength, well durability attributes such resista...

The production of ordinary Portland cement (OPC) as the most expensive constituent of concrete is associated with destructive environmental effects and significant energy consumption. Thus, the use of supplementary cementitious materials such as Natural or synthetic pozzolans is a fundamental solution that affects the kinetics of hydration of cementitious materials. In this article, to evaluate...

In fiber concretes, microcracks in the boundary area between the cement paste and the surface of aggregates or fibers are higher. Natural and artificial pozzolans can be used for reinforcing this area. In this research, the combination of glass fiber, zeolite, and nano silica particles were used in lightweight self-compacting concrete containing scoria. Fiber volume fractions between 0% to 1.5%...

Glass fiber reinforced cement (GRC) is an excellent composite for architects and engineers because it can be molded to produce laminar panels or create complicated designs. GRC a fine concrete with alkali-resistant glass fibers at 3–5% per mass. However, durability limited of the aggressiveness alkaline medium produced during Portland hydration (effect portlandite). The objective this study ass...

Sulfur cements have drawn significant attention as binders because sulfur is a byproduct of fossil fuel refining. that can be formed by the vulcanization elemental and plant-derived olefins such terpenoids are particularly promising from sustainability standpoint. A range terpenoid–sulfur shown compressional flexural properties exceeding those some commercial structural mineral cements. Pozzola...
