2.Shape of Coarse Aggregates: The shape of the aggregate is a crucial characteristic because it impacts the workability & strength of the concrete. In general, the angular aggregate is desirable for round and smooth sets for the following reasons: The angular aggregate shows a better interlocking effect which gives a better concrete.

smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make high-strength concrete, it is easier to do so with coarse aggregates below 12.5 mm (Y, in.) (ACI 363-95).

COARSE AGGREGATE. Coarse aggregates refer to irregular and granular materials such as sand, gravel, or crushed stone, and are used for making concrete. In most cases, Coarse is naturally occurring and can be obtained by blasting quarries or crushing them by hand or crushers. It is imperative to wash them before using them for producing concrete.
