STUDY ON STRENGTH OF CONCRETE USING VARIOUS COARSE AGGREGATES, PART-11

4.2 Details of mix design

The mix ratio is 1:2:4

Diameter of the cylinder = 6 inch.

Height of the cylinder = 12 inch.

Volume of the cylinder = Π/4X6²X12   in³          

                                         = 0.196 ft³           

Wet volume = (0.196 X 1.5) = 0.294 ft³  

Quantity of cement = 0.294 X 1/7 X 50 X 1/1.25

                                  = 1.68 kg

Quantity of sand = 0.294 X2/7 X100 X 1/2.2

                             = 3.82 kg

Quantity of brick chips = 0.294 X4/7 X 68.5 X 1/ 2.2

                                         = 5.23 kg

Quantity of stone chips = 0.294 X 4/7 X 95X 1/ 2.2

                                         = 7.25 kg
