Hi All,
Recently i come across that there are some measurments for the Roof slab strength like M15, M20 and M25. For these measurements, M15, M20 and M25 what is the Mix ratios of Cement, Sand and Crusher Stones (which can be used for construction).
Please help me to get this information and i really appreciate for the help.
Regards,S Ravuri.
Dear Ravuri
These are grade of cement concrete as M 15, M20, M25. M15 denotes that the ratio of cement concrete is 1:2:4 means 1 part of cement, 2 parts of course sand and 4 parts of bazri ( stone ballast 12mm to 20 mm)
M20 denotes that the ratio of cement concrete is 1:1.5:3 means 1 part of cement, 1.5 parts of course sand and 3 parts of bazri ( stone ballast 12mm to 20 mm)
M25 denotes that the ratio of cement concrete is 1:1:2 means 1 part of cement, 1 parts of course sand and 2 parts of bazri ( stone ballast 12mm to 20 mm)
