In this study, the authors investigate various properties of coal gasification slag fine aggregate (CGS) when applied to high-strength concrete. The amount admixture using CGS concrete is lower than that ordinary initial compressive strength and onset up 91-day age were smaller those aggregate. Young’s modulus approximately 1.1 times reduced autogenous shrinkage only in case portland cement. mo...

River sand is becoming increasingly scarce. As a result, an alternative material required to replace river in order save sand. In the construction of quality concrete, artificial aggregate now frequently employed as substitute for Coconut fibre ash (CFA) obtained from prevalent India. Partially replacing (fine aggregate) with presaturated CFA self curing purpose presented paper. Fine aggregates...
