High-Strength Concrete (ACI 363R)

2005-6-1  High-strength concrete has shown a higher rate of strength gain at early ages as compared to lower-strength concrete, but at later ages the relative difference is not as significant. Information on creep and shrinkage of high-strength concrete has indicated that the shrinkage is similar to that for lower-strength concrete.

Concrete Compression Analysis Santa Rosa Junior College

2005-12-7  The ultimate strength of concrete is related to water/cement ratio and the size, shape, and strength of the aggregate used. Concrete with lower water/cement ratio (down to 0.35) makes a stronger concrete than a higher ratio. Concrete made with smooth pebbles is weaker than that made with rough-surfaced broken rock pieces for example. Properties
