The mechanical properties of aggregates may or may not have an effect on the strength or durability of concrete. Since concrete is an assemblage of individual pieces of aggregate bound together by a cementing medium, its properties are based primarily on the quality of the cement paste. Its strength is dependent also on the bond between the cement paste and the aggregate. If either the ...
