Match and calculate sand, gravel, and cement quantities using the concrete proportion table: Volume * Cement Multiplier for a Class "A" in 40 kg bags = 0.90m3 * 9 = 8.1 bags. The volume of sand is equal to the quantity of sand. For a Class "A" mix, the sand multiplier is 0.90m3 *.5 = 0.45m3. Gravel Quantity equals Gravel Volume.
concrete divided by the weight of cement in the concrete. The water to cementitious ratio, W/Cm, is the weight of mix water in the concrete divided by the weight of the cementitious material, where the cementitious material is a combination of cement and pozzolans. The ratio is expressed as a decimal (example 0.446).
= 0.4 × wt. of cement =0.4 × 554.44 kgs = 221.776 kgs = 222 liters ( 1kg= 1 liter) Note: This w/c ratio holds good if you use plasticizers. Practically for good workability, the water we add for the concrete is 250 to 270 liters. Alternate method: 1. Volume of cement ( from above) = 0.385 cum. 2. Volume of sand = [volume of cement × b]
