Abstract

The investigation of brick compressive strength has been done for 60 samples. Tests was carried out by the experimental method using a compressive strength testing machine (Compression Machine). The highest compressive strength for pressed brick from Tenayanraya was 0.86×107 N/m2 that fulfills grade 50 and the highest compressive strength brick for conventional brick is 1.128×10 7 N/m2 fulfill grade 100. The bricks that made in Rumbai has the highest compressive strength, that is 1.484×107 N/m2 which fulfill grade 100. The compressive strength of the conventional brick was 1.592×107 N/m2 which fulfill grade 150. Based on the results of testing, the entire samples produced from Tenayanraya and Rumbai agrees the Indonesian National Standard (SNI) SK-SNI-S-04-1989-F. The difference in compressive strength is not too large for Tenayanraya difference is 0.268×107 N/m2 and for Rumbai difference is 0.108×10 7 N/m2. The difference in brick compressive strength attributed to the differences in the processing of raw clay (clay) and the difference in location of the position of bricks during the combustion process
