Concrete Mix Design: Understanding Aggregate

Angular aggregates are preferred for manufacturing high-strength concrete because of an improved bond between the aggregate and paste The types of aggregates considered unsuitable for concrete mixing are flaky, elongated or a combination of both Flaky aggregates tend to be aligned in one plane, thereby causing issues with concrete durability...

Coarse Aggregate Angularity

Overview The coarse aggregate angularity (CAA) test is a method of determining the angularity of coarse aggregate (Figure 1) Coarse aggregate angularity is important to ensure adequate aggregate interlock and prevent excessive HMA deformation under load () Figure 1: Angular Coarse Aggregate The CAA test estimates coarse aggregate angularity by visually inspecting a small sample of coarse ....
