摘要：The aim of the present work is to study the behavior of conventional aggregate concrete replaced withpumice aggregates in volume percentages of 0%, 20%, 40%, 60%, 80% and 100% and cement replaced with the silicafume in weight percentages of 0%, 5%, 8%, 10%, 15% and 20%. The conventional mix has been designed for M20grade concrete. In this investigation cubes, cylinders, beams and slabs of standard size have been cast and tested after28days of curing period. Three specimens have been cast for each variable and thus totally 540 specimens are tested.With 20% pumice stone in the normal coarse aggregate and cement replaced with silica fume in weight percentages of0%, 5%, 8%, 10%, 15% and 20%, compressive strength, split tensile strength, flexural strength and moment carryingcapacity of concrete specimens increase upto 5% of silica fume and then decrease. With 40% pumice stone in thenormal coarse aggregate and cement replaced with silica fume in weight percentages of 0%, 5%, 8%, 10%, 15% and20%, compressive strength, split tensile strength, flexural strength and moment carrying capacity of concrete specimensincrease upto 8% of silica fume and then decrease. With 60% pumice stone in the normal coarse aggregate andcement replaced with silica fume in weight percentages of 0%, 5%, 8%, 10%, 15% and 20%, compressive strength,split tensile strength, flexural strength and moment carrying capacity of concrete specimens increase upto 8% of silicafume and then decrease. With 80% pumice stone in the normal coarse aggregate and cement replaced with silica fumein weight percentages of 0%, 5%, 8%, 10%, 15% and 20%, compressive strength, split tensile strength, flexuralstrength and moment carrying capacity of concrete specimens increase upto 8% of silica fume and then decrease. With100% pumice stone in the normal coarse aggregate and cement replaced with silica fume in weight percentages of 0%,5%, 8%, 10%, 15% and 20%, compressive strength, split tensile strength, flexural strength and moment carryingcapacity of concrete specimens increase up to 10% of silica fume and then decrease.
