Clay bricks with shred geogrids

Abstract

This session presents a survey and the performance of the role of shred geogrids in mud brick's compressive strength and a comparison of it with the normal mud bricks. Mud brick consists of clay, water and different materials. Its massive use may become an important evaluation due to its low cost and higher compressive strength compared to the concrete blocks. Many experiments conducted on earth blocks without any addition material, report about its low compressive strength. Thus, many testing on the strength of the mud brick, with different additional materials were done. These different additions may be shred tires, which consist in narrow strips of rubber. Another material is the shred geogrids, which consists in polyester strips grid. The paper articulates the change of compressive strength of mud bricks with these different additional materials. This is evident in the compressive test days 3,7,14 and 21 where the results show that due to different bricks with normal mud bricks and shred geogrids with sizes of 10cm×10cm×10cm, have 20% moisture content. The tires are one of the materials that cause environmental pollution and it is used less after consumption in the automotive industry, thus we used a cheap material for surveying the strength in mud brick. As well the geogrids are used in soil stabilization, where they have additional pieces in construction, so we used them in mud bricks. The results show that performances of mud bricks with shred geogrids were better than normal mud bricks.
