Abstract: |
The present paper focuses on investigating characteristics of M40 concrete with various proportional replacement of cement with Ground Granulated Blastfurnace Slag (GGBS) and steel fibre. High Performance Concrete (HPC) is a concrete meeting special combinations of performance and uniformity requirements that cannot be always achieved routinely by using conventional constituents and normal mixing. This leads to examine the admixtures to improve the performance of the concrete. Considering cost of construction also drawn the attention of investigators to explore new replacements of ingredients of concrete. Six mixes were studied with GGBS & Steel Fibre using a water binder ratio of 0.38 and superplasticizer CONPLAST SP-430. The cubes and cylinders were tested for both compressive and split tensile strengths GGBS can enhance the durability aspects of HPC compared to control mix. Among the mixes, the mix with replacement level as 10%,20%,30%,40% and 50% of GGBS and 1% steel fibre is better with respect to strength and durability. Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. It is found that by the partial replacement of cement with GGBS and steel fibre helped in improving the strength of the concrete substantially compared to normal mix concrete. |
