Concrete Mix. The following is a design guide for selecting proportions for initial concrete mix design for normal weight concrete. It contains a mix ratio is 1361 cement 3 sand and six aggregateM-15 M represents the mix while 15 Nmm2 is the concrete cubes characteristic compressive.
It contains a mix ratio is 1361 cement 3 sand and six aggregateM-15 M represents the mix while 15 Nmm2 is the concrete cubes characteristic compressive. M stands for mix. The concrete is placed on the surface to be covered and is compacted in place using large heavy rollers typically used in earthwork.
The cone is then lifted clear.
Accurate concrete mix design makes concrete construction economical. The concrete mix ratio refers to the proportion of the components in the concrete. Mixing ratios are based on what psi concrete you need. M15 concrete grade concrete gets categorized as an ordinary grade.
