Abstract
Housing price in Malaysia is unaffordable for most middle to lower income citizens. This is due to, Malaysia has been using massive amount of conventional construction materials such as concrete, fired earth bricks and cement-based bricks, which are expensive and hazardous to the environment. The Interlocking Compressed Earth Brick (ICEB) has been proved to have numerous advantages over the conventional method, including the ability to reduce overall building construction costs. The ICEB is the mixture of soil, sand, water and stabilizer such as cement. Agricultural by-products such as Eco-Processed Pozzolan (EPP) can be used to partially replace cement percentages in ICEB. However, the optimum design and the effect of EPP on ICEB’s strength and durability are unknown. Therefore, this study was conducted to establish the optimum mix design of ICEB units using 10%, 20%, 30%, 40% and 50% EPP as partial cement replacement based on compressive strength. In addition, determination of water absorption, porosity, crystallographic as well as the morphology of ICEB units has been carried out to study the effect of EPP towards the durability properties of the ICEB units in terms of water absorption and porosity. Based on the laboratory test results, 20% of EPP as partial cement replacement with 16% water absorption and 31% porosity is chosen as an optimal replacement level because it uses high amount of EPP in design mixture without affecting the compressive strength and durability of the ICEB. Therefore, EPP may be recommended as an admixture in the construction of green buildings and structures in the future.
