Cement formation and calculations
Step 1 of 5
We Know that concrete is made up of cement, fine aggregate, coarse aggregate and water by
weight.
Therefore,
Vol. of concrete = [
𝑉𝑜𝑙. 𝑜𝑓 𝑐𝑒𝑚𝑒𝑛𝑡 + 𝑉𝑜𝑙. 𝑜𝑓 𝑓𝑖𝑛𝑒 𝑎𝑔𝑔𝑟𝑒𝑔𝑎𝑡𝑒
+ 𝑉𝑜𝑙 𝑜𝑓 𝑐𝑜𝑎𝑟𝑠𝑒 𝑎𝑔𝑔𝑟𝑒𝑔𝑎𝑡𝑒
]+ Vol. of air in concrete
+𝑉𝑜𝑙. 𝑜𝑓 𝑤𝑎𝑡𝑒𝑟 𝑏𝑦 𝑤𝑒𝑖𝑔ℎ𝑡
Here, we have given the mix proportions as
IC: 2.5FA: 3.5CA: 0.5W by weight
Step 2 of 5
The weight of cement (We) required in 2 yd3 (54 ft3) of concrete can be calculated using the
equation given bellow:

Where
The specific weight of water is 62.4ib/ft3
The specific gravity of cement is 3.15,
The specific gravity of fine aggregate is 2.65,
The specific gravity of coarse aggregate is 2.75,
The specific gravity of water is 1.
Step 3 of 5
The proportion of cement is 1
The proportion of fine aggregate is 2.5
The proportion of coarser aggreg...
