Plain brickwork is not capable of taking any tensile stress. By providing reinforcement of steel bars or flats or wire mesh the brickwork would be able to withstand some amount of tensile force. Such brickwork is known as reinforced brickwork. Good quality bricks of class designation 7.5 and above and cement mortar not leaner than 1:4 is used in such a construction. Reinforced brickwork can be used in the construction of retaining walls. In half brick masonry it is the general practice to provide at every third or fourth course, reinforcement consisting of two 6 or 8 mm dia bars or hoop iron of dimension 25 mm x 3 mm. Half the mortar for the joint is first laid, the reinforcement placed and the remaining mortar laid so that the steel is fully embedded in the mortar.
