Using the Kaolin With Coir, Rice Straw and Rice Hush in concrete Masonry Unit Wall for Increasing Effective Heat Protection
MetadataShow full item record
The objective of this research project is to develop an effectively applicable prevention of heat for concrete masonry unit wall. By using kaolin mixture coir, rice straw and husk as a major ingredient in concrete to replacing usual stone dust, the hollow non-load-bearing concrete masonry units obtained had the size of 70 X 190 X 390 mm. The test results showed that the reliably ideal ratio of these mixture materials had to be from the combination of kaolin, coir, rice straw and husk, by replacing them at 5%: 5%: 15% and 50/0. The block obtained also had other certain qualifications such as Weight at 6.08 kg., water absorption at 7.96%, and compressive strength at 65.4 ksc. Moreover, these combined materials harbored heat capacity less than the standard concrete masonry units with the weight not more than 29%.
