EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

2014-1-8  To predict the behavior of concrete under general loading requires an understanding of the effects of aggregate type, aggregate size, and aggregate content. This understanding can only be gained through extensive testing and observation. There is strong evidence that aggregate type is a factor in the strength of concrete.
