The cement industry is one of the main producers of carbon dioxide (CO2) for production of one ton of cement approximately one ton of CO2 is released into the atmosphere. To reduce the cement content different supplementary cementitious materials (SCM’s) like fly ash, silica fume, alccofine, metakaolin, rice husk ash, Ground granulated blast furnace slag (GGBS) were used. In the present investigation SCM’s like fly ash and alccofine were used, In the first stage, cement is partially replaced by fly ash at various percentages such as 20%, 30%, and 40% by weight of cement to produce an optimum content of percentage of fly ash. In the second stage, by keeping this optimum percentage of Fly ash (FA) as constant further cement is replaced by Alccofine (AF) at 5%, 10% and 15% by weight of cement. The mechanical tests like compressive strength (CS), split tensile strength (STS) and flexural strength (FS) were studied, beside this the durability properties like sorptivity, rapid chloride penetrability test (RCP) were studied. The obtained results showed that the combination containing 30% fly ash and 10% alccofine exhibited superior results when compared with conventional concrete.

Fly ash, Alccofine, compressive strength, split tensile strength, flexural strength, water sorptivity and rapid chloride permeability test.
