Estimating the cost of new concrete involves much more than the price of concrete per yard (or meter). There are many variables to consider, such as surface prep, formwork, reinforcing materials, and finish work, plus the cost of the ready-mix concrete, that will add up to the total price of the job.
For example, if the concrete mix ratio of M20 concrete is 1:1.5:3 then 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume should be taken to produce concrete. Prescribed concrete Mix ratios for all grades of concrete are given below
For calculation, We consider a nominal concrete mix proportion of 1:2:4 (~M20). Step-1: Calculate Weights of materials required To arrive at different quantities of concrete ingredients, the Dry loose bulk density of materials plays important role as they are batched loosely.

How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.
Generally ready mix concrete costs lower. Also it varies with site location and size of construction. M20 or M25 RCC concrete costs around 4000 to 4100 per cubic meter and PCC concrete costs around 3400 to 3500 per cubic meter. Most construction in India is done in M25 grade of concrete.
Call a local ready-mix company, tell the supplier what the concrete is for, and ask about the best mix (proportions of cement, gravel and sand). For a shed, the supplier will probably suggest a mix with a capacity of about 4,000 psi (pounds per square inch). If you live in a region with freeze/thaw cycles in winter, ask for 5 percent air entrainment to help the concrete withstand freeze/thaw ...
2014-08-30· So if we take 'A' cum of cement, we must take '1.5A' cum of sand and '3A' cum of course aggregate. So the total volume = A + 1.5A + 3A = 5.5A To make 10 cum of concrete, we must take a total volume of 15.2 cum of cement, sand and aggregate put
