Study of Rn-222 emanation from fabricated composite brick based on treated sugar cane fibre


Mohamad Razapi, Nor Fatihah (2018) Study of Rn-222 emanation from fabricated composite brick based on treated sugar cane fibre. Final Year Project thesis, Universiti Malaysia Kelantan. (Submitted)


In this study, Radon Sentinel model 1030 was used to determine the level of Rn-222 concentration on three brick fabrications that contained different raw material ratios such as cement, sand, and stone. This study is aimed at fabricating fabricated brick based sugar cane using alkali treatment. In addition, this fabrication is also intended to assess the degree of mechanical strength of the composite brick. Each fabricated brick will be placed in a perspective box for a three-day period to measure the level of the brick radon using the Sentinel Radon model 1030. The Perspex boxes have been subjected to the degree of radon content in the box. Data was taken for three days every 30 minutes. The entire data taken amounted to 114 data for each fabricated composite brick. Additionally, each fabricated brick has different raw material content such as brick composite 1 having less sand, brick composite 2 has less rock and brick composite 3 having less cement content. The reduction is aimed at studying which raw material produces high levels of radon, whether sand, stone or cement. Before the raw material was included in the composite brick, this raw material was calculated for Rn-222 level for one day and obtained 48 data. Each raw material handling, it has been replaced with a 10g sugar cane content for each fabricated brick. Levels of radon concentrations are also influenced by several factors for example temperature, pressure, or humidity level of the area. Data for each composite brick were taken and based on that data, composite bricks 1 had high levels of radon concentrations compared to composite bricks 2 and composite bricks 3. Data for brick that did not have sugar cane fiber was also taken and readings of radon concentrations for the bricks were lower compared to the fabricated composite brick. This is because sugarcane fibers used in fabricated brick composites have a high carbon level and have good water absorption levels. This causes a humidity stage in high composite bricks and at the same time causing a radon concentration stage for composite brick fabrication is also high. The use of sugar cane fiber in composite brick fabrication can reduce the use of raw materials for brick making and thus reducing the cost of brick making.
