MoreThe 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 - table 2, Clause 4.1 and 4.2 for single size aggregate as well as graded aggregate.
