DEVELOPMENT OF CLC BLOCK WITH COCONUT COIR PITH MIXTURE FOR HEAT INSULATION IMPROVEMENT

Abstract

This research applied aerated concrete technology. It aims to create new products that are more insulating and add value to the waste material. In this research, aerated concrete and coconut coir pith were combined to meet the objective. Both materials have good heat insulation properties, especially coconut coir pith. Coconut Coir pith has a coefficient of thermal conductivity = 0.023 (W/m-K), so it is good insulation. When using coconut coir pith, it can reduce the amount of materials in the production of high-priced aerated concrete, such as cement and sand, and reduce the amount of heat that spreads into the building than conventional building materials. The test is used TIS 2601 - 2013 standard to control the production of cellular lightweight concrete system and to test the thermal conductivity (Thermal conductivity, K, ASTM C518). The result was that cellular lightweight concrete with coconut coir pith was effective in reducing heat effectively.
