Brick/mortar bond strength is needed to minimize moisture penetration and withstand tensile stresses due to laterally applied loads, movement or settlement of the masonry elements and temperature changes [1]. With mortar joints being typically 3/8” wide, and assuming standard size bricks, the mortar joint comprises approximately 16 percent of the area of the masonry surface. various mortar mixes of different grades such as M1 and M2 have different strengths, but it does not affect the strength of brickwork. Strength. The building code for weight-bearing brick walls calls for mortar to be no more than 3/8 inch thick.

Following factors affect the strength of cement mortar for the same ratio of cement and sand: The plasticity property of cement mortar mix also varies with the fineness of the sand for the same ratio of cement and sand. Mortar is the bonding material between bricks, concrete block, stone, and many other masonry materials.It is made from Portland cement, lime, sand, and water in varying ratios. Fill the horizontal segments first, before filling the verticals. Bonding of lime mortar with bricks is better. For example, Cement-sand ratio of 1:6 has mortar strength of 30 kg/cm2 and brickwork strength of 5.5 kg/cm2, while cement-lime and the sand-mix ratio of 1:1:6 has mortar strength of 30 kg/cm2 has higher brickwork strength of 7 kg/cm2.
