Strength Appraisal of High Grade Concrete by using High Reactive Metakaolin

Abstract

The need of High Grade Concrete is increasing day by day . Also , the availability of natural sand which is a major component of concrete is becoming difficult. With the use of artificial sand instead of natural sand for producing High-grade concrete by using High Reactive Metakaoline may solve the problem. Hence the investigation was carried to study the effect of metakaolin addition on compressive strength and rapid chloride permeability of concrete. The tests were carried out on concrete specimens with 0, 4,6 and 8 % replacement of cement by metakaolin . It was observed that there was a substantial increase in compressive strength and reduction in rapid chloride permeability due to metakaolin addition in concrete. Hence it was concluded that metakaolin clay is the best material for producing high grade concrete with an improved engineering properties.
