Bambrick

Abstract

Abstract— This study aims to evaluate the effectiveness of Bambrick, a concrete and bamboo mixed brick, as an alternative building material compared to conventional brick. The three main objectives of this study 
are to examine the temperature differences within the structure, assess the rate of water absorption, and evaluate the sound insulation capability of Bambrick in comparison with ordinary brick.For the first objective, brick samples were exposed to direct sunlight for one hour at an ambient temperature of approximately ±33°C. The outer and inner surface temperatures were measured using an infrared thermometer to determine the temperature difference (ΔT). For the second objective, brick samples were produced using a mixture of cement, sand, water, and bamboo fiber with bamboo content variations of 0%, 5%, 10%, 15%, and 20%, and then cured for 14 days. Water absorption tests were conducted using the 
immersion method for 24 hours and 3 days, followed by dry and wet weight measurements to calculate the percentage of water absorption. For the third objective, the sound insulation test was carried out using a brick test box placed 50 cm from the sound source, and the difference in sound level was measured using a Mini Sound Level Meter. The findings show that Bambrick recorded lower internal temperatures compared to ordinary brick, indicating better thermal insulation capability. In addition, bricks without bamboo content showed a higher water absorption rate compared to Bambrick, indicating improved moisture resistance when bamboo fiber was incorporated. In terms of acoustics, Bambrick was found to be 
effective in reducing sound transmission compared to conventional brick. In conclusion, Bambrick has high potential as a more efficient building material in terms of thermal insulation, water resistance, and sound insulation, making it a better alternative to ordinary brick
