27-03-2020· F'ck = fck + factor based on grade of concrete, whichever is higher For M30 grade concrete Factor based on grade of concrete = 6.50. Standard Deviation = 5.00 F'ck= 30 + 1.65 X 5 = 38.25 N/mm2. F'ck = 30 + 6.5 = 36.50 N/mm2. Hence higher value of F'ck = 38.25 N/mm2 is to be used for design calculations.
The maximum water-cement ratio to design M30 grade concrete can be found from Table 5-IS456 given above. Maximum W/C ratio =0.45: Table 5-IS456: Adopted W/C ratio =0.45: You can reduce the water-cement ratio for M30 grade concrete based on your requirements, but remember that Water-cement ratio directly affects the strength of the concrete.

06-10-2019· Component of Concrete . Here are only four major components that are usually required for concrete formation. Cement, Sand, Coarse aggregate, and water with a suitable proportion of water.. All of these components are mixed according to batching or Concrete grade table, Maybe M10, M20, M25, M30, etc. Mostly M25 and M30 always used in construction industries for multistory buildings.
Step 4 – Calculation of Cement Content. Water-Cement Ratio = 0.50. Water content from Step – 3 i.e. 197 liters. Cement Content = Water content / "w-c ratio" = (197/0.50) = 394 kgs. From Table 5 of IS 456, Minimum cement Content for moderate exposure condition = 300 kg/m3. 394 kg/m3 > 300 kg/m3, hence, OK. As per clause 8.2.4.2 of IS: 456
For example, for M30 grade, the mix proportion can be 1:1:2, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight of materials. The strength measure with concrete cube or cylinders by civil engineers at the construction site.

Estimated water content = 186+ (3/100) x 186 = 191.6 kg /m 3 Step 4 — Selection of Cement Content Water-cement ratio = 0.5 Corrected water content = 191.6 kg /m 3 Cement content = From Table 5 of IS 456, Minimum cement Content for mild exposure condition = 300 kg/m 3 383.2 kg/m 3 > 300 kg/m 3, hence, OK.This value is to be checked for durability requirement from IS: 456.
If the designed concrete mix fails to meet the desired properties then minor adjustment is done in the water cement ratio and aggregate quantities, then again the trial mixes are prepared. Hope this post helped you to learn the step by step procedure for concrete mix design using IS code ( IS – 10262: 2009 and IS – 456: 2000)
Standard Concrete Mix Ratio M30 to M45 grade concrete mix ratio is designed manually. For example, M45, cement volume, sand (fine aggregate), and coarse aggregate are batched in quantities according to the design mix. From the table above to the M45 grade, these concrete ratios are called nominal mix concrete.
