Strength Modeling of High Strength Concrete

Abstract

Silica fume is being used all over the world for many years in the area where high strength and durable concrete were required, and it also improves the characteristicsof both fresh and hard concrete. Incorporation of the silica fume increases the mechanical properties of high strength concrete than the conventional concrete. Standard cylinders and standard prisms were considered in this study and the specimens were cast with and without silica fume. Mechanical properties such as compressive strength, split tensile & flexural strengths of high strength concrete of grade M60 were determined with various replacement of silica fume ranges from 0% to 15%. The experimental results of this research indicate that the optimum percentage of silica fume in concrete is 12%. This paper presents the mathematical model for predicting the strength of the silica fume high strength concrete. The result from this studyrecommends that the model hasachieved remarkably well in predicting the strength of concrete mix.
