production of concrete mixes

Designing sustainable concrete mixes with potentially ...

Concrete is one of the mostly used construction materials, but the production of concrete with ordinary Portland cement (OPC) has caused significant environmental burdens. In this study, five mixes of concrete were designed with commonly used binders and potentially alternatives materials to evaluate the mechanical and environmental ...
