There are various cement to sand ratios for each element of the building construction. It is generally as follows:-. 1) For masonry construction block/ brick work, ratio of cement to sand is = 1:3, 1:4, 1:5 and 1:6. 2) For …

1) cement consumption for plastering external brick wall :- For a Sample calculation, I will assume a 20mm thick plaster and a mix ratio of 1:4 for plastering of 1m2 brick wall. Step-1: we know given area of brick wall = 1m2. Step-2: Volume of internal wall plaster = Area X Thickness = 1 X 0.020 = 0.020 cu m.

The "classic" mix: 3 parts rendering sand and 1 part building sand with 1 part cement for the first coat (called a 4:1 scratch coat). The second coat (called a float) is usually 5 parts rendering sand to 1 part cement with plasticizer (this is a 5:1 float coat). In recent years, I've met tradespeople who are using a 6:1:1 mix:

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.
