FUNDAMENTAL PROPERTIES OF HIGH-STRENGTH CONCRETE USING COAL GASIFICATION SLAG FINE AGGREGATE

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. moderate heat cement, same as land sand
