Typically, most of renders are made of Portland cement, sand, water, lime and some approved admixture ingredients, commonly used, suitable, best and standard mix for cement render is 1 parts cement to 1 parts hydrated lime to 6 parts sand by volume, which is represented as 1:1:6 (1 cement: 1 lime: 6 sand), for this mix any general purpose cement can be used and sand should be fine and clean of impurities, coarser sand is usually used for base layer and finer sand for the top layer. Subscribe our Youtube Channel What is the best mix for cement render ![]() ![]() Typically, most of renders are made of Portland cement, sand, water, lime and some approved admixture ingredients, standard mix for lime render is 1 parts cement to 1 parts hydrated lime to 6 parts sand by volume, which is represented as 1:1:6 (1 cement: 1 lime: 6 sand), for this mix any general purpose cement can be used and sand should be fine and clean of impurities, coarser sand is usually used for base layer and finer sand for the top layer. It is the most commonly used, best, satisfactory and standard mortar mixture.įor most of work like brickwork, block work and rendering is 1 parts Portland cement to 1 parts hydrated lime to 6 parts sand by volume, which is represented as 1:1:6 (1 cement: 1 lime: 6 sand), for improving plasticity, flexibility and workability of lime cement mortar, a suitable mix like 1 parts Portland cement, 2 parts lime and 9 parts sand as 1:2:9 also can be used. This proportion of Portland cement sand and lime based on volume used for rendering of external and internal walls. Portland cement sand and lime mix ratio is 6:1:1 indicates 1 part of cement mixed with 6 parts of sand and 1 part of lime. Portland cement sand and lime mix ratio for rendering Portland cement plaster is a plaster mix in which portland cement or combinations of portland and masonry cements or portland cement and lime are the principle. Typically, mix ratios of 3:1:12 and 2:1:9 are used for foundations and retaining walls, 1:1:6 used for block work rendering, and brick work, and 1:2:9 used for non load bearing structure. The typical Portland cement sand and lime mix ratio are 1:1:6 (1 cement:1 lime:6 sand), 3:1:12 (3 cement:1 lime:12 sand), 2:1:9 (2 cement:1 lime:9 sand), and 1:2:9 (1 cement:2 lime:9 sand). Mix ratio for M type mortar is 3 parts cement to 1 parts lime to 12 parts sand which is represented as 3:1:12 (3 cement: 1 lime: 12 sand). Standards for Plaster and Stucco Containing Portland Cement. This type of mortar has compressive strength of 2500 psi or 17 Mpa. Type – M mortar:- this type of mortar used for heavier load bearing structure below the ground application, generally it is used for foundation and retaining wall. Mix ratio for S type mortar is 2 parts cement to 1 parts lime to 9 parts sand which is represented as 2:1:9 (2 cement: 1 lime: 9 sand). This type of mortar has compressive strength of 1800 psi or 12.4 Mpa. Type – S mortar:- this type of mortar used for load bearing structure below the ground application, generally it is used for base for foundation and retaining wall.
