Abstract: Carbonation is one of the imperative properties that affect the durability of concrete especially in case of reinforced structures. In this present study, an attempt has been taken to study the effect of M sand and other supplementary cementitious materials like silica fume, fly ash and steel slag as a partial replacement to cement. Different combinations with M sand, river sand and combinations of M sand and river sand with supplementary cementitious materials at water to cement ratio varying from 0.45 to 0.5 was studied. Results revealed that the complete replacement of river sand by M sand reduced the rate of carbonation but addition of supplementary cementitious along with either river sand or M sand resulted in increase over the rate of carbonation compared to conventional concrete.
Keywords: Carbonation, Fly Ash, M sand, Silica Fume and Steel Slag.
Scope of the Article: Composite Materials
