Why to use block jointing adhesive instead of mortar?

Traditional mortar made up of cement, sand and water has much higher strength and low flexibility. Hence, when AAC blocks expand at higher temperatures, traditional mortar, due to it's stiffness will not allow the blocks to expand. This will generate high internal stresses in blocks and will develop cracks. These cracks may further result to weakening of plaster, dampness in wall and other health hazards. Hence, self curing block jointing adhesive containing cement, fine sand, polymers and water must be used to joint AAC blocks. Highly flexible adhesive will ensure that enough room is provided to blocks for thermal expansion.
