Proportions for 3000 lb. per sq. in. Concrete

Based on 28-day compressive strength of 6x12 in. cylinders.

Proportions are expressed by volume as follows: Portland Cement : Fine Aggregate : Coarse Aggregate.

Thus 1:2.6:4.6 indicates 1 part by volume of portland cement, 2.6 parts by volume of fine aggregate and 4.6 parts by volume of coarse aggregate.

Quantities of Materials for 1 cu. yd. of 3000 lb. per sq. in. Concrete

.

The volume of cement is expressed in barrels and of aggregates in cubic yards.
F = fine aggregate; C= coarse aggregate.

Quantities are net, no allowance being made for waste; for average conditions, the following additions are suggested: Cement, 2%; fine aggregate, 10%; coarse aggregate, 5%.
