how to calculate mortar for block work

To go further, let us assume that we have 150 m2 of wall, and we want to estimate the quantity of cement and sand needed to lay the blocks. For horizontal, I have no problem since there 10 blocks per square metre. The typical arrangement of blocks in a one square metre wall is shown below; Therefore, we can estimate the volume of mortar required to build one square metre (1 m2) of wall as follows; Vertical mortar = 8 x (0.025 x 0.225 x 0.275) = 0.0123 m3Horizontal mortar = 10 x (0.0637 x 0.025) = 0.0159 m3Total = 0.0282 m3. Block required. That’s my view, I want you to shed more light on this. A wall measuring 10 feet by 10 feet has an area of 100 square feet, for example. Thus, the total dry mortar required for 1 cum brick masonry is.30cum. Good job Brother. When the mortar per m² is established, multiply that by the total area of the works. Considering voids in sands, we assume that materials consists of 60% voids. Therefore, we can estimate the volume of mortar required to build one square metre (1 m 2) of wall as follows;. Multiply the length of the wall by the height of the wall to obtain the surface area. Here is how you can calculate the amount of block needed the old fashioned way using a pencil and paper: How to calculate concrete blocks needed: 3 Bags Mortar per 100 Block (35 Block … Cement mortar is used in various proportions, i.e. If there is a need for an additional coat don’t do that at one go.
