River sand : 735 Kg/ M 3 
Total water : 200 Kg/ M 3 
Admixture : 0.7% 
Fresh concrete density: 2400 Kg/ M 3 
Note: sand = 735 + 2%, Water = 200- 14.7 = 
185.30, 
Admixture = 0.7%
M40 ( 1 : 1.67 : 2.39) 
Cement : 430 Kg/ M 3 
20 mm Jelly : 618 Kg/ M 3 
12.5 mm Jelly : 412 Kg/ M 3 
River sand : 718 Kg/ M 3 
Water Cement ratio : 0.43 
Admixture : 0.7% 
Note: Sand = 718 + Bulk age 1%
M45 ( 1 : 1.58 : 2.26) 
Cement : 450 Kg/ M 3 
20 mm Jelly : 626 Kg/ M 3 
12.5 mm Jelly : 417 Kg/ M 3 
River sand : 727 Kg/ M 3 + Bulk age 1% 
Water Cement ratio : 0.43 
Admixture : 0.7%
M50 ( 1 : 1.44 : 2.23) 
Cement : 450 Kg/ M 3 
20 mm Jelly : 590 Kg/ M 3
