    M40 grade stands for it’s a mix of concrete with a characteristic compressive strength of 40 N/mm2. The mix design procedure for M40 grade concrete as per ACI Method is discussed. Contents:M40 Grade Concrete Mix Design Procedure1. Required Data2. Mean Design Strength3. Water-Cement Ratio4. Water Content and Air Content5. Cement Content6. Coarse Aggregate

  • Mix design M25 Grade designed as per IS 10262:2009 & IS

    From Table 3 of (IS 10262:2009) Volume of coarse aggregate corresponding to 20 mm size aggregate and fine aggregate (Zone II) for water-cement ratio of 0.50 =0.62 . In the present case water-cement ratio is 0.44. Therefore, volume of coarse aggregate is required to be increased to decrease the fine aggregate content.
