If more than 6 litres of water is needed, the sand is unsuitable. Masonry blocks 390 x 190 x 190mm. The mortar ratio you speak of is determined by the strength of the brick that you are laying for example soft thermalite type blocks would require a very weak mix or a class A engineering brick would be 3:1 sand cement ratio When we say the cement-sand ratio is 1:4, we mean that the mortar contains one part of cement and four parts of sand. At all. Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer. Typical mix ratio for mortar (laying of blocks) is 1:6.
