COARSE AGGREGATES IN HIGH STRENGTH CONCRETE

2014-5-12  Given the critical role that the interfacial transition plays in high-strength concrete, the mechanical properties of coarse aggregate will have a more pronounced effect than they would in conventional-strength concrete. Important parameters of coarse aggregate are shape, texture, grading, cleanliness and nominal maximum size.
