1.Size of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used.

UNILAG Post UTME is always on a grade 30. Let assume you have 20 out of the 30, this will make it 20%. Your total aggregate will then be JAMB score (35%) + WAEC/NECO/GCE grade (16.8%) + Post UTME Grade (20%) = 71.8%. Note: Candidate Must Score MINIMUM OF (12/30) in Post-UTME and score 200 and above in JAMB to be considered for admission.

Any aggregate particle that retains of sieve #4 is called ‘coarse aggregate’. Coarse aggregates (also known as crushed stones) are majorly added in the concrete mix for strength gain purposes. They can be obtained by blasting heavy rock boulders. In Pakistan, we generally use Margalla Crush, Sargodha Crush and Sakhi Sarwar Crush
