ANALYSIS ON COMPRESSIVE STRENGTH OF CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT WITH ALCCOFINE

The presence of Alccofine in the conventional concrete in optimum dosage can be expected to improve the compressive strength and provide resistance against chloride attack, sea water attack and accelerated corrosion attack. The
main objective of this work focuses on the compressive strength of concrete with partial replacement of cement with
Alccofine. The project focuses on the experimental investigation on concrete by replacing cement with Alccofine on varying percentage. 0%, 4%, 8%, 16%, 17%, 20%, 25%, 50%, 75% and 100% for 7 and 28 days. The design mix carried
out throughout the experiment was M25. The increase in percentage of compressive strength for 7 days and 28 days curing was found to be maximum at 16% replacement exhibiting the value of 50.95 % and 60.95% when compared with conventional. Alcoffine in various percentages improves the strength of concrete initial period. Alccofine acts as filler materials such that reduces permeability improving workability of fresh concrete. Overall it is a comparative study governing compressive strength as main point of contradiction.
