Importance of Aggregate Gradation of concrete slab

2019-10-25  Properties of aggregate gradation for concrete slab. The shape and texture of aggregate affects the properties of fresh concrete more than hardened concrete. Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate. (AASHTO M 6) are: 1. The fine aggregate must not have more than 45%
