Abstract

This research aims to produce scrap page kaolin of brick construction. The kaolin clay ratio of 100: 0, 80:20, 60:40, 50:50, 40:60, 20:80 and 0: 100 by volume, Add mixed with rice husk and rice 15 percent by weight, A total of seven ratios. According to standard tests or TIS. 77-2545 ordinary story brick building. The moisture content and water absorption is increasing. While density Thermal conductivity resistance, flexural and compressive strength tends to decrease. The best ratio of 80:20 by volume, with compressive strength 43.16 kg / cm 2 and 24.93 percent water absorption. Criteria standard of TIS. 77-2545 requiring compressive strength not less than 35 kg / cm2, and water absorption must not be higher than 25 percent. Can be used in the manufacture of brick construction, including building decorative wall can be developed into products. Because skin color and beautiful
