NFLUENCE OF INDUSTRIAL BY-PRODUCTS ON THE BEHAVIOR OF HIGH-PERFORMANCE CONCRETE

The by-products obtained from industries such as Silica Fume (SF) and Fly Ash (FA) can be utilized to improve the strength and durability of High-Performance Concrete (HPC). The application of these industrial by-products is becoming common all over the world because of the reduction of their potentially dangerous effects on the environment. This paper investigates the behavior of Silica Fume as a fractional replacement to Ordinary Portland Cement (OPC) on the parameters such as water permeability, compressive strength, split tensile strength and flexural tensile strength of High-Performance Concrete (HPC). HPC mixes with silica fume contents of 0 %, 5%, 7.5%, and 10% and a constant proportion of 10% fly ash was adopted in the trial mixes. Superplasticizer in optimum dosage was added to achieve required workability. Tests were conducted to determine the optimum proportion of Silica fume which yields appreciable Fresh and hardened state properties.
