Abstract:
An experimental study investigated the influence of four coarse-aggregate types available in Northern California on the compressive strength and elastic behavior of a very high strength concrete mixture. Using identical materials and similar mix proportions, the diabase and limestone aggregates were found to produce concretes with significantly higher strength and elastic modulus than did the granite and river gravel. The mineralogical differences in the aggregate types are considered to be responsible for this behavior.
