Quantity of materials required for 1 cubic metre of cement mortar | quantity of cement sand in mortar | quantity of cement and sand in different mix ratio 1:2, 1:3, 1:4, 1:5, 1:6 & 1:8.

Mixture of cement sand and water is known as cement mortar. For preparing mortar first a mixture of cement and sand is made roughly mixing them in dry condition with the help of shovels. Water is gradually added and mix with Shovels. Generally water is added to the mix is about 20% of dry volume.

Cement mortar is used for various purpose it is used to bind masonry units such as stone, bricks, cement blocks, to plaster slab and external and internal walls which make them impervious. It is used to give neat finishing to walls and concrete works, for pointing masonry joints, preparing building blocks, used as a filler material in ferro cement works, to fill joints and cracks in walls & used as a filler material in stone masonry.

There are various cement to sand ratio or mix proportion used to prepare cement mortar such as 1:2, 1:3, 1:4, 1:5, 1:6 & 1:8. When 1 part of cement is mixed with two part of sand then it is called 1:2 mix ratio, 1 part of cement is mixed with 3 part of sand then it is called 1:3 mix ratio, 1 part of cement is mixed with 4 part of sand then it is called 1:4 mix ratio, 1 part of cement is mixed with 5 part of sand then it is called 1:5 mix ratio, 1 part of cement is mixed with 6 part of sand then it is called 1:6 mix ratio and 1 part of cement is mixed with 8 part of sand then it is called 1:8 mix ratio.

Cement to sand proportion recommended for various work are following:- 1) to bind masonry units such as stone, bricks, cement blocks 1:6 to 1:8 mix ratio are best to use, 2) to plaster slab and external and internal walls 1:3 to 1:6 mix ratio are best to use which make them impervious, 3) mix ratio 1:4 is highly recommended for concrete and ceiling plastering, 4) mix ratio 1:3 is used for repairing purpose and 5) mix ratio 1:2 to 1:3 used for pointing.
