    Abstract

    A constant increase in population growth rate has resulted in rapid urbanization, more development indicating more waste. The rising number of waste tyres disposal is a serious issue as the recycling of the waste tyres is extremely low, let alone reusing it for a beneficial purpose. Besides that, rising demand from the government of Malaysia to improve the wall partition aestheticism while replacing the conventional masonry walls to reduce the total deadweight of a building. This study is conducted to investigate the suitability of a lightweight experimentally, cost-effective and simple rubberized lightweight foamed concrete (RLFC) sandwich wall panel under load-bearing, load-deflection and flame-exposure test. Calcium silicate board is chosen to act as the outer skin, while rubberized lightweight foamed concrete is chosen to act as the inner core of the sandwich wall panel. Several mix trials were conducted, and a final composition of 0.55-P-80 was chosen. Calcium silicate boards are equipped mainly to resist harsh environmental conditions and extreme heat, while RFLC is responsible for holding structural load. Many researchers concluded that RFLC is sufficient to act as a non-load-bearing wall panel as it has sufficient load-bearing strength while having a low thermal conductivity that can improve the energy efficiency of buildings. For load-deflection and load-bearing tests, the test specimen suffered a crushing behaviour when subjected to an ultimate load of 1500 kN and 16.4 kN respectively. Only one main crack was observed for the flame exposure test when the test specimen was subjected to continuous flame exposure up to 60 minutes. The highest temperature recorded at the backside of the test specimen was 104 °C, which satisfies the ISO 834-1 requirement, which stated that the temperature recorded at the backside of the test specimen should not be more than 180 °C. The present study showed that calcium silicate board has high fireproof effectiveness while RFLC is suitable for the inner core of the sandwich wall panel.
