International Conference on African Development Archives

Concrete is one of the versatile and widely used building material in the world construction industry. Fine and coarse aggregates make about 70% by volume of concrete production. It goes without saying that the quality of concrete is thus strongly influenced by aggregate’s physical and mechanical properties as well as chemical composition of the parent aggregate making material. This calls for a critical identification and classification of aggregates so that they are used to meet the intended purpose.

In this article, the physical, mechanical, and chemical properties of aggregates are reviewed. The sources and modes of production of coarse and …
