Abstract

Generally, bricks are used as building structural wall materials and dwelling. This study aims to find out the strength of the brick wall pairs when receiving a lumped load of the roof structure of a mixture commonly used by the community is 1 PC: 8 Sand and 1 PC : 10 Sand so as to avoid cracks in the wall due to the roof structure load. This test used  local bricks from Tumpang Malang with Model M-6B 230 mm x 110 mm x 55 mm. Another materials obtained from the building store in Malang City. The testing method used is SNI 03-4166-1996 robust test procedure for compressing red brick. The test method used is SNI 03-4166-1996 about the test procedure of compressive strength of red brick masonry wall. The dimensions of specimens is 75 x 64 cm as much as 3 samples of each thickness variation, where the thickness variation is 3 cm, 4 cm, and 5 cm so that the number of sample objects test all 18 specimens. Further test object tested press using UTM according SNI 03-4166-1996. The result showed that the average compressive strength of brick masonry wall was 1 PC : 8 Sand on variation of thickness of 3 cm, 4 cm, 5 cm, respectively by 8.26 kg/cm², 7.63 kg/cm², 7.4 kg/cm². The average compressive strength of brick masonry wall of 1 PC : 10 Sand on variation in thickness of 3 cm, 4 cm, 5 cm, respectively by 8.11 kg/cm², 6.91 kg/cm², 6.46 kg/cm².
