May 14, 2020  Abstract. Portland cement (PC) is the most energy-intensive-based material, and also requires a huge amount of natural resources. At present, cement industries contribute 7% of the total CO 2 emission into the atmosphere which results in increase in global warming effect. To control this negative effect, an alternative material is being developed.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, (water resistant) such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for ...
