The Influence of Coarse Aggregate Shape on the Properties of High-Performance, Self-Compacting Concrete

High-performance, self-compacting concrete (HPSCC) represents a very significant step in the development of concrete technology. The most important features of SCC are specific rheological properties which include flowability, segregation resistance and passing ability. Therefore, a crucial requirement is to maintain an appropriate balance between the slump flow and plastic viscosity of concrete mixtures. In general, the rheological properties are modified by effective superplasticisers and a proper ratio of water to binder. The aim of this study is to focus on the important aspect of the impact of shape of the coarse aggregate on fresh concrete mixture properties and the strength of high-performance, self-compacting concrete (HPSCC).
