Agro-Industrial Aerated Concrete: Insulation for Thermal Reduction in Building Eeydzah Aminudin, Mohd Fadhil Md. Din, Mohd Warid Hussin, Yo Ichikawa, Nobuya Hiroshiba, and Rahmah Zalani Abstract---This paper presents a comparative study aiming in investigate the heat impact for different percentages of Palm Oil Fuel Ash(POFA) for agro-industrial aerated concrete based on their thermal behaviors.In aerated concrete production , aluminum powder is used to create pores which lead to thermal insulation property. Besides that, the bottom ash has being used as sand replacement and performance of POFA replacing binder content at percentages of 0, 10, 20 and 30 by weight has being identify. In order to investigate the thermal performance on the building material, surface temperature sensors, data logging systems together with Infrared thermometric were used respectively. Thermal images will simply rectify the behavior of outdoor surface temperature by having the “heat impact”. The results indicate that 30 per cent of POFA aerated concrete has the better improvement in thermal conductivity and had the capability to absorb and released the heat in shorter time. The study proved that the higher the time lagged hence lower the thermal insulation properties. Keywords--Agro-industrial aerated concrete; Building materials; Thermal images; Heat impact; Time lagged I. INTRODUCTION Tropical countries normally have an ambient of hot and humid at all season. The drastic change from ambient temperature within this 3 years time gave a huge impact in our society. Back in 2012, [1] has discovered the maximum ambient temperature to be 37.2 ˚C. Now the ambient temperature recorded as 41˚C. The vibrant change in construction contributes to the additional caused of global issues. Moreover, single skin wall normally used in construction are chosen in the design as it is cheap but thermally, the building will eventually feel hot. Due to this problem, people tend to use up the air-conditioning.

Thermal Insulation is one of key factor for assessing the material composition of building envelops. This is because the behavior of materials will determine the properties which are important for urban thermal balance. Besides that the long term benefit of insulation is that it may reduce the cost of cooling as well as reducing the pollution of the environment [2]. Heat from solar radiation will be absorbed and the infrared will radiate and dissipate part of the accumulated heat through convective, conduction and radiation. Some of heat will reradiate back to the atmosphere causing the increasing of ambient temperature. Thus, technical characteristics of materials used need to comply with determination degree of energy consumption and comfort conditions of individual buildings as well as of open spaces [3]. Aerated concrete known as lightweight concrete that has been used in current construction materials. Such invention, lots of other extensive research progress aiming in improving the thermal, hygric and other structure properties. Majority, researched innovation conducted in Table 1 proved that either the replacement of cement or fine aggregate proven that the it might lower the density as well as thermal conductivity hence create a better insulation. As been cited by [4] the reduction of density of mortar means probably due to high air content. This has been agreed in Fu and Chung, 1997 cited [2] study showed that low thermal conductivity is related to high air void. However, study showed by [5],proved that the thermal conductivity differ, depends upon the pore structure of the lightweight aggregates, density of concrete and the cement paste matrix. Thus, the pore structure is one of the main factors affecting thermal conductivity. Still the limitation study shows that this non load bearing structures rarely proves the percentage of wastage improve this behavior of thermal including the value of thermal conductivity and the improvement in heat flux. Hence for this segment the researcher would like to discuss the behavior of adding and combining the wastes from Agricultural and Industry can improve the behavior of thermal conductivity, as improving the thermal comfort. Develop an efficient building materials is important as to minimize the consumption of electricity [9].
