What Is Coarse Aggregate Uses and Classification of the
2024.3.26 Coarse aggregate is a term used to describe the larger-sized particles that form the bulk of concrete mixes. These particles are typically greater than 4.75 mm (0.187 inches) in diameter. Coarse aggregates are obtained from natural sources, such as quarries, or can be manufactured by crushing rocks or recycling concrete waste.

How Coarse Aggregate Affects Mix Design of Concrete?
The voids left by larger coarse aggregate particles are filled by smaller coarse aggregate particles. Proper grading of coarse aggregate can minimize the possibility of segregation, especially for higher workability and improves the compatibility of concrete. The coarse aggregate grading limits are given in ASTM C33/ C33M and IS 383 – 1970 ...
