Add 3 parts sand and 1 part masonry cement. Mortar mix ratio i.e. Proper proportioning of mortar ingredients helps in having the following advantages: Uniformity of strength Uniform workability Uniform color Uniformity of proportions and yields Mainly the proportioning of the cement and sand for mortar are conducted […] I hope now you understood how to calculate quantity of materials in brickwork. To achieve a flow of 100%, the water–cement ratio differs amongst mortars with different compositions. Depending on the manufacturer of the cement, it is recommended to have the cement mortar ratio for plastering by mixing required amount of sand, lime and other aggregates. 04.

The various mixes are quoted as volume ratios, however the individual components are normally sold by weight, so a little calculation work is required. We've assumed: There is a 10% allowance for wastage of both bricks/blocks and mortar included in this calculation. Mix mortar for laying flagstones, flooring, bricks and tiles. Water retentivity of cement–soil mortars is more than that of conventional cement–sand mortar. 1:5 ratio of mortar impart compressive strength of 5.0 N/mm2 after 28 days of cube testing. Specifications calling for such ratios of 1:2, 1:3 or 1:1 lime to sand are misleading lime:sand Both substances have different purposes, as the cement is activated with water and forms a connection with other elements to form a solid object , while the mortar is useful to keep bricks or stones together and cannot be alone like concrete.
