Volume of fine aggregate in mix = 1 – 0.558 = 0.442

Hence,Volume of coarse aggregate per unit volume of total Volume of concrete = 0.62 x 90% = 0.558 (Note 2: For pumpable concrete or congested reinforcement in structure the coarse aggregate proportion may be reduced up to 10%) If the coarse aggregate is not of an angular shape, the volume of coarse aggregate is required to be increased suitably, based on experience-based.)

If the water-cement ratio is more than 0.5, the volume of coarse aggregate is to be reduced to increase the fine aggregate content. The volume of coarse aggregate is required to be increased to reduce the fine aggregate content in the mix. (Note 1: For every ☐.05 increase or decrease change in w/c, the coarse aggregate proportion is to be changed by 0.01. Table for Correction in Estimation of Coarse Aggregate Proportion

The volume of coarse aggregate per unit volume of Concrete = 0.62.

Maximum cement content for mix = 450 kg/m 3.

Hence cement content adopted = 383.2 kg/m 3.

In this example for mild exposure and for reinforced concrete, the minimum cement content is 300 kg/m3 which is less than 383.2 kg/m 3.

This value is required to be checked for durability requirements from IS: 456 – 2000.

Maximum water-cement ratio taken for Mild exposure condition = 0.55Īssume the water-cement ratio as 0.50 for the experiment base S = Standard Deviation (N/mm 2) = 4 (Refer: IS 10262- 2009 table -1) Step-2 Determining Water-Cement ratio Himsworth constant for 5% risk factor is 1.65 & standard deviation is taken from IS: 456 2000 for M – 25 Grade of concrete is 4.0. The following steps are to be followed for concrete mix design calculation, Step-1 Determining the Target Strength of Concrete

(e) Fine aggregates are confirmed to Zone II of IS – 383 (d) Aggregates are assumed to be having surface dry conditions. 10×10 Room Construction Cost Excel Sheet.Construction Material Testing Menu Toggle.30×40 House Plans | 1200 sq ft House Plan.20*50 House Plan | 1000 sq ft House Plan.
