A comprehensive review of partial replacement of cement in concrete
Green concrete's physical and chemical characteristics were addressed and evaluated in comparison to regular cement concrete. The following conclusions can be made considering the literature review: Various investigations have demonstrated that more than 25% replacement is not preferred in the case of RHA substitution for Portland cement.
