Effects Of Aggregates 19 mm And 25 mm Maximum Sizes On

Coarse river sand with fineness modulus of 3.0 with water cement ratio of 0.4 was used to produce the said concrete using mix ratio 1:1.5:3 (cement:sand:granite). The coarse aggregate sizes namely 19 mm and 25 mm were also used along separately. The cement was subjected to specific gravity, fineness, consistency, setting time,
