CONCRETE MIX DESIGN AND QUANTITY CALCULATION
Concrete Mix design and Quantity Calculation Concrete is a composite mixture of Cement Sand & Aggregate. We use concrete in structure because of its load bearing ability. Here the term Concrete Mix design introduced. It is the process where we find the mixing ratio of concrete ingredient to achieve desire strength. Here strength is compressive in nature. As per IS-456:2000 different grade of concrete and desire compressive strength are mention bellow. SL NO GRADES OF CONCRETE RATIO OF CONCRETE (CEMENT : SAND :AGGREGATE) CHARACTERISTIC COMPRESSIVE STRENGTH OF 150MM CUBE AFTER 28DAYS OF CURING 1 M5 1:5:10 5 N/ mm2 2 M7.5 1:4:8 7.5 N/ mm2 3 M10 1:3:6 10 N/ mm2 4 M15 1:2:4 15 N/ mm2 5 M20 1:1.5:3 20 N/ mm2 6 M25 1:1:2 25 N/ mm2 7 M30 1:0.75:1.5 30 N/ mm2 8 M35 ...
