Effects Of Aggregate Type Size And Content On

increase in aggregate size results in a decrease in the compressive strength of concrete. Cook 1989 showed that, for compressive strengths in excess of 69 MPa 10,000 psi, smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used
