Aggregate in Concrete - The Concrete Network

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.

Concrete Mix Design: Understanding Aggregate - NPCA

2018-3-2  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

2015-1-11  Physical characteristics of aggregates have a significant influence on the performance of concrete. Compared to conventional concrete, the mix design of highly flowable concrete is more complex and should ensure that the mixture can develop adequate static and dynamic stability. The selection of aggregate plays a major role for the mix design and mixture optimization of flowable concrete
