(Dry mix method) We will calculate quantities of materials for 1 m3 of concrete (By volume). Let us assume the mix proportion is 1 : 2: 4 (Cement : Sand : Stone = a:b:c) Volume of wet concrete = 1 m3. Volume of dry concrete = 1 × 1.54 = 1.54 m3.

WebJul 28, 2024 · The difference in mean compressive strength 28 days = (35.00-34.82) = 0.18 N/mm 2 (99.49%). It may be concluded that in the concrete mix design calculation the mean compressive strength after 7 and 28 days of curing is found out to be 23.70 N/mm 2 and 34.82 N/mm 2 respectively, which is less than the required strength of M35.
