EXPERIMENTAL STUDY ON THE BEHAVIOR OF CONCRETE BY REPLACEMENT OF FINE AGGREGATE WITH GRANITE POWDER AND CEMENT WITH ALCCOFINE 1203- A REVIEW

Environmental concerns caused by the extraction of raw materials and CO2 emissions in the production of Portland cement led to pressures to reduce the consumption of this constituent of concrete, combined with the need to increase its durability. The cement is the most costly and energy intensive component of concrete. The unit cost of concrete can be reduced as much as possible by partial replacement of cement with other waste pozzolanic materials. Certain materials of mineral origin are also added to concrete to enhance their strength and durability properties of concrete materials such as Granite Powder needles and other by product like Alccofine-1203. Granite powder and alccofine can be used in a combination as supplementary cementitious material as partial replacement of cement and Fine aggregate. 15% alccofine with 15% Granite powder (K3) gives 32% increase in compressive strength which is 31.65N/mm2 of this newly modified concrete in comparison with conventional concrete of M35 grade which is optimum amongst other combinations within 7 Days. 15% alccofine with 15% Granite powder (K3) gives 34% increase in compressive strength which is 38.45 N/mm2 of this newly modified concrete in comparison with conventional concrete of M35 grade which is optimum amongst other combinations within 14 Days. 15% alccofine with 15% Granite powder (K3) gives 42% increase in compressive strength which is 48.07 N/mm2 of this newly modified concrete in comparison with conventional concrete of M35 grade which is optimum amongst other combinations within 28 Days. 15% alccofine with 15% Granite powder (K3) gives increase in Tensile strength which is 2.76N/mm2, 3.23N/mm2 and 3.89N/mm2 within 7 Days, 14 Days and 28 Days alternatively. 15% alccofine with 15% Granite powder (K3) gives increase in Flexural strength which is 8.6N/mm2, 9.1N/mm2 and 10.5N/mm2 within 7 Days, 14 Days and 28 Days alternatively. Percentage increase in Granite Powder results in decrease of strength parameters i.e. combination having 20%, 25%, 30% of Granite Powder gives less increase in results for this mix proportion.
