For eg a concrete mix of proportions 124 means that cement fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement two parts of fine aggregate and four parts of coarse aggregate The proportions are either by volume or by mass The

The proportions of cement sand coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete So care should be taken while calculating the amount of Cement Sand and Aggregate required for 1 Cubic meter of Concrete Method1 DLBD method to determine material requirement for 1 Cum concrete The DLBD Dry Loose

What is Grade of Concrete Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control Grade of concrete is denoted by prefixing M to the desired strength in MPa For example for a grade of concrete with 20 MPa strength it will be denoted by M20 where M stands for Mix

We have considered an entrained air of 2 Thus the actual volume of concrete for 1 cubic meter of compacted concrete construction will be 1 002 098 m 3 Thus the quantity of cement required for 1 cubic meter of concrete 09801345 729 bags of cement The quantities of materials for 1 m3 of concrete production can be calculated as
