gate reduces the unit volume of cement paste and provides an internal restraint that significantly reduces the magnitude of these volume changes in concrete. In addition to drying shrinkage, the cement paste is also subject to carbonation shrinkage. Shrinkage results from the Fig. 3.1—Cracking of concrete due to drying shrinkage.

However, due to the variability of mix ingredients the nominal concrete for a given workability varies widely in strength. Nominal mix ratios for concrete are 1:2:4 for M15, 1:1.5:3 for M20 etc. Standard Mixes or Ratio The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under or over-rich mixes.

A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.
· Mix grade is the method to find out the proportion of cement sand and aggregate for getting the desired strength of concrete. Actually Nominal mix is done on the basis of volumetric batching which is more costly for higher grades. CONCRETE MIX DESIGN M-25 - RCC A-1):- Design stipulation :-(a). Grade of concrete = M25
M25 = 1:1:2 Total mix = 1+1+2 = 4 Dry quantity of one cum. Of C. Concrete = 1.54 Quantity of cement = 1×1×1.54 / 4 = 0.385 cum. Number of bag = 0.385/0.034 = 11.32 Say, 11 bag of cement. Thank-you

· Concrete Mix Ratio by Volume. Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. The volumetric mix ratio of M20 concrete is 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.
· Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY; Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio

So the volume of dry material for concrete is achieved by multiplying wet concrete by 1.54. Based on same reason if we want to get volume of dry material for mortar wet volume should be multiplied by 1.20. However some engineers add 5% to 10% to multiplicative figure of 1.54 or 1.20 to account for wastage and poor workmanship.)
The dry volume of concrete mixture is always greater than the wet volume. The ratio of dry volume to the wet volume of concrete is 1.54. So 1.54 Cum of dry materials (cement, sand and aggregate) is required to produce 1 Cum of concrete. Volume of Cement required = 1/(1+2+4) X …
The average cost of concrete delivery is $119 to $147 per cubic yard for a full 10-yard truckload of ready-mix concrete, and $172 per yard for a short-load of less than 10 yards.
