“…A building material with proper physical and mechanical characteristics as well as thermal properties in respect to radiation will contribute towards controlling heat transmission through it. Decreasing thermal conductivity of material is the dominant factor in reducing heat that could be transferred to or from the building [1]. The components of the building envelope, which include walls, windows, doors, roofs, etc., represent the most expensive conduit of heat gain of the building.…”

Abstract. The consumption of energy for cooling the indoor environment of buildings in Malaysia is high and mostly related to poor thermal performance of the building envelope. It is evident that reducing energy consumption of buildings has become vital, taking into considerations the limitation of conventional energy resources and the adverse effects associated with the use of such type of energy on the environment. Therefore, selecting the proper thermal properties of a building envelope play a major role in determining the energy consumption patterns and comfort conditions in enclosed spaces. The objective of this study is to investigate the potential application of rice husk (RH), corn cob (CC) and waste tea (WT) as an additive agent in a fired clay brick manufacturing to produce an improved thermal conductivity of final brick product. In the execution of this study, these agricultural wastes were mixed together with clay soil in different percentages, ranging from 0 %, 2.5 %, 5 %, 7.5 % and 10 % by weight. Physical and mechanical properties including soil physical properties, density, shrinkage, water absorption, compressive strength as well as thermal conductivity were measured, reported and discussed in accordance with BS 1377: Part 2: 1990, BS 3921: 1985, MS 76: 1972: Part 2 and ASTM C 518. The results show that RH at 7.5 % is the most effective combination to achieve low thermal conductivity of fired clay brick. This finding suggests that RH waste is a potentially good additive material to be used for thermal properties enhancement of the building envelope.

“…Similarly, to further enhance the effectiveness as a thermal barrier, these cavities can be filled with other materials that possess even better properties to achieve this objective. Studies on incorporating waste materials into bricks is not new as this can help to reduce the amount of waste materials disposal at the same time [4,5].…”

The main objective of this paper is to reduce the amount of external heat penetrating the building wall, hence reducing the cooling load requirements and eventually the electricity consumption. Expanded polystyrene and wood sawdust were chosen as filler material to reduce the thermal conductivity in perforated bricks because both are commonly found waste products with good potential due to their lightweight, low thermal conductivity and high specific heat. It was found that bricks with polystyrene recorded the lowest temperature change. Although sawdust has a much higher thermal conductivity, the temperature change is almost similar to that of polystyrene. This could be attributed by the higher density of wood, which means more mass are occupying the same volume of space. Hence, the paper found that thermal conductivity, specific heat capacity and density of the filler material can influence the effective thermal conductivity of the perforated brick.

Eco-brick is an important environment-friendly strategy to mitigate carbon dioxide emission in building construction. For energy and resource efficient of eco-brick manufacturing, natural fibre and biomass waste can be utilised as matrix. The present study aims to evaluate the properties of concrete eco-brick manufactured using kenaf fibre matrix. The brick was produced by mixing kenaf fibre (MR grade), Portland cement and sand. The physical and mechanical properties of the eco-brick were evaluated according to the ASTM C73 method. The water absorption values of the eco-brick were in the range of 9.0-12.5 %. Eco-brick produced from 0.5, 1.0, 1.5% and 2.0% kenaf fibre have flexure resistance to compression of 4693.9, 4335.6, 3879.3 and 3294.5 psi respectively. According to the ASTM C73 guidelines, the properties of eco-brick from mixture of 0.5-1.5% kenaf fibre produced in this study meet building material criteria for construction in moderate weather conditions.
