The Role of Additives and Admixtures in the Making of Concrete

 · Concrete additive is a substance that isn't basic raw material, but exceeds 5% of the cement mass in the concrete. These are generally sand or aggregate. An admixture in concrete is a material which is added during the mixing process. This mixture shouldn't be more than 5% of cement content which modifies the fresh or hardened concrete's property. Type of
