Thermal Conductivity of Concrete Blocks Inserted Natural-Rubber Sheet Mixed with Banana Stalk

Abstract

The purpose of this research was to apply the thermal insulation properties of natural rubber sheet mixed with banana stalk. The study was set up into two steps. The first step was to study the thermal conductivity of natural rubber sheet mixed with banana stalk ranging of 0, 2, 4, 6, 8 and 10 phr. The second step was to study the thermal conductivity of concrete blocks inserted with the natural rubber sheet mixed banana stalk. It was found that the coefficient of thermal conductivity of natural rubber sheet mixed with banana stalk having the thickness of 1 and 3 mm wrer 0.0031 and 0.0120 W/ m-K, respectively. The coefficient of thermal conductivity of the concrete blocks inserted with natural rubber sheet mixed with banana stalk were 0.0023 and 0.0070 W/ m-K, respectively.
