Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubic') compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are …

There are three phases in the development of a concrete mixture: specifying, designing, and proportioning. Water/cement ratio (w/c ratio) theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher ...

Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and 1600 kg/m 3 (bulk density ...

CALCULATION FOR AGGREGATE QUANTITY. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3. Aggregate = (3/5.5) x 1.54 = 0.84 m3 ∴ 3 is a part of cement, 5.5 is sum of ratio. Density of Aggregate is 1500/m3. Calculation for KG = 0.84 x 1500 = 1260 kg. As we know that 1 m3 = 35.31 CFT.

M25 concrete ratio is 1:1:2 by volume. It indicates the nominal ratio of cement, sand and aggregate. It simply means that if 1CFT cement is used for making concrete, you should use 1 CFT sand and 2 CFT aggregate. (i.e. 1 part cement: 1 part sand: 2 parts aggregate). M25 concrete ratio for 1 cubic meter is (cement: sand: aggregate): 1:1:2 ...
