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.
Highlights
West Sumatera is located on the west coast of the island of Sumatera, which in recent years have often shaken by earthquakes with a high scale
Damage caused to the building is on the wall, made of clay brick
Clay bricks are used as a buffer to the existing load on it, such as the construction of houses and foundations
Summary
West Sumatera is located on the west coast of the island of Sumatera, which in recent years have often shaken by earthquakes with a high scale. If the strength of the clay brick used is not the same with SNI and other standards, it will be very dangerous for the safety of people living in the building [1]. This should be our common concern, how to create and process quality clay brick accordance with SNI. 2) The compaction pressure of a clay brick process. 3) Firing temperature of the fuel of rice husk is very low (600oC), should be 1000oC [1] To resolve this problem, further research is needed, so that the clay brick produced meets quality standards. This research is a continuation of our earlier research team, focused on reviewing the compaction pressure, which is a requirement to get the results of quality bricks
