Abstract

Concrete in construction is classified as ordinary concrete or high strength concrete. This variation is determined by the strength of concrete. Usually high strength concrete shows the strength up to 100MPa where as for normal concrete itis not more than 50MPa. The present study deals with flow and strength properties of M60 grade concrete containinga constant proportion of Al2O3 and varying proportions of silica fume. Nano-sized particles of Al2O3 are used with 0.25% by weight of cement. Silica fumes are used in the proportions of 0, 5, 10, 15, 20 and 25% by weight of cement. Cube specimens with the dimensions of 150×150×150 are casted and tested for 3, 7 and 28 days compressive strength. It is observed that the Workability of concrete is decreased by increasing the quantity of silica fume. Compressive strength of hardened concrete started increasing and maximum attained at 15% of silica fume by weight of cement and again decreased. The cement particles when replaced with nano Al2O3 and silica fume performs better when compared with conventional concrete.
