Answer (1 of 7): How much cement, sand and aggregate are required for 1m³ of M25 concrete M25 concrete ratio: M stand for mix and numerical figure 25 is compressive strength of concrete is 25N/mm² for curing time of 28 days and M25 concrete ratio is 1 : 1 : 2, mixture of cement, sand and aggreg...
Get PriceThus, the quantity of cement required for 1 cubic meter of concrete = / = bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = x 50 = kg. Weight of fine aggregate (sand) = x .
Get PriceSo you need to mix 14 bags of cement with 1 cubic yard (27 CF) of sand and 3/2 yard of gravel to produce 3000 psi concrete. Therefore a mix using 1 cubic yard of sand should require 14 bags of Portland cement and about 3/2 cubic yards ( CF) of gravel to produce 3,000 psi concrete. Primary Sidebar. Categories.
