Abstract: Three of Light Foamed Concrete (LFC) have been obtain by using different formula of Cement:Aggregates. The brick was locate into a closed Perspex box and the net of 222Rn concentration level have been measured for 5 consecutive days. The results show the LFC 3 has produced the lowest of net 222Rn concentration level in air, followed by LFC 2 and LFC 1, respectively. The result also show the 222Rn concentration level have been influenced by the temperature and relative humidity in air.

Abstract: Malaysia is one of the main crude oil exporters among countries in Association of South East Asian Nations, ASEAN. Therefore, oil is widely used in many sectors, especially in transportation sectors, and it will produce a lot of oil-based waste that will harm environment. Activated carbon can help to treat this waste by using the permeable reactive barrier (PRB) concept. At the same time, Malaysia is also an agricultural based country which produces a massive amount of agricultural waste. In this study, sugarcane bagasse, corn cob and pineapple's core is chosen to produce activated carbon by using furnace heating processing and microwave processing.
