Concrete Mix Ratios - Cement, Sand, Aggregate and Water
Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

How To Calculate Cement, Sand & Aggregates Quantity in
Aug 03, · Some of Mix is – 5.5. Where, M = Mix 20 = Characteristic Compressive strength. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY
Different concrete mix grades? - M10, M15, M20, M25
Oct 21, · In concrete mix grades “M” presents concrete mix design ratio and the number after “M” presents MPa or N/mm 2 compressive strength of concrete. For example M10, M15, M20, M25 concrete mix grades. There are different types of concrete mix grades in civil engineering according to their need and use.
