Question

15% 11. At a construction site the following materials are available : 5 tons of cement, 8.2 tons of wet (SSW) sand and 16.5 tons of dry gravel, 1.5 tons of water. In the laboratory the surface moisture of sand is determined to be 8%. The absorption capacities are 3% for each aggregate. SSD Bulk specific gravities are 2.60 for sand and 2.65 for gravel. Specific gravity of cement is 3.10.

It is required to produce concrete with the following proportions:

Cement=325kg/m3

Sand (SSD)=730kg/m3

Gravel (SSD)=1125kg/m3

Water(net)=180kg/m3

Calculate the volume of concrete that can be produced with the available material at the field.
