Optimization of compaction pressure on brick

Abstract

Bricks are one of the building materials that serves as a wall or anchoring the load. Therefore, it must be made according to the standards. In our previous observations, many found bricks were traditionally not quality, because the process of making bricks that are not right. Bricks are a class of ceramic materials that must be hard and should not be crushed when immersed in water. The method in this study focuses on optimizing compaction pressures, with printed pressures that are varied in MPa units. The results obtained as follows, in terms of mechanical properties of Compressive Strength increases with the addition of compaction pressure, an increase of 36% (brick becomes strong). In terms of physical properties of Density increased (porosity becomes smaller). For Suction rate down, this shows less water absorption. The results obtained in accordance with national and international quality standards.
