APPRAISAL ON THE STRENGTH OF CONCRETE PRODUCED WITH VARYING AGGREGATE SIZE

Compressive strength is one of the important properties of concrete as it influences the durability requirements of concrete. This work presents the effects of varying size of aggregate on the strength of concrete. The coarse aggregates used for this study were 10mm, 12.5mm and 19mm uncrushed gravel with river sand as fine aggregate. Sieve analysis was carried out on the aggregates. A nominal mix of 1:2:4 was adopted for the mix and the mix proportions were calculated by weight.
