An Experimental Study on the Properties of the Concrete made with Blast Furnace Slag, Fly-Ash or Paper Sludge-Ash

In recent years, problems of industrial solid wastes appear to be kind of national crises, caused by a sudden increase in their quantities, lack of disposal technique, and public discontent in installing plants for their disposal. This study is designed to investigate that pozzolana-based materials, such as blast furnace slag, fly-ash, paper sludge-ash, which are produced from industries as solid wastes, can be used as construction materials. The variations of concrete strength in function of compositional differences of raw materials including the wastes are studied experimentally. As a result, we find out that the blast furnace slag, the fly-ash, and the paper sludge-ash can be recycled as useful resources for replacement of cements by adjusting their substitution ratio.
