Commonly, reinforced concrete, timber and steel are used as a frame structure acting as a structural member for load transmittal to the foundation and bricks are used in construction industries only as infill. Bricks can also be used as an external and internal load bearing walls, however the use of bricks as a load bearing structural element is relatively few in Malaysia. With the use of this structural masonry method of construction, faster and cheaper construction can be achieved. The savings in terms of using formwork and reinforcing steel can be made and the rate of construction can be reduced since frames are less or not required at all and the waiting time for the structural concrete to cure can be eliminated. The effects of using different type of material for brick making in construction environment are suggested to study. In the preliminary studies on identifying the suitability of locally produced bricks as load bearing walls, Kartini & Siti Hawa (2001) found that a unit of calcium silicate bricks and sand cement bricks gave a compressive strength of 10.30 N/mm' and 8.59 N/mra' respectively. So by acting axial load are applied on top of the brick walls built with mortar, in order to determine the structure behavior of the wall as load bearing wall and this is carried out by erecting two units of calcium silicate brick walls and two units of sand cement brick walls of size 1000mm x 1000mm. the thickness of the wall is Vi brick. However, the study concluded that calcium silicate brick wall showed better performance, with maximum lateral displacement of 4.85 mm, vertical deflection of 14.41mm and ultimate load of 803.45 kN.
