Analysis of the Optimum Usage of Slag for the Compressive Strength of Concrete [PDF]

Materials, 2015
Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive strength of concrete mixtures increases. However, after an optimum point, any further increase in slag does not improve the late-age compressive strength ...
