| Abstract | This research aimed to investigate the effect of rice husk ash as a reinforcing material (Pozzolan) in the production of lightweight bricks with dimensions of width 20 cm, length 60 cm, and thickness 7.5 cm (lightweight brick size according to the standards of the Department of Industrial Promotion). Production of non-autoclaved system type 1 uses light materials in the production process include portland cement, fine sand, aluminum powder, lime, gypsum, and reinforcing materials (finely rice husk sintered at 600oC for replacing sand in the amount of 3 formulas, such as 5 wt%, 10 wt% and 15 wt%). The brick was cured with water for seven days. Testing properties of lightweight bricks include compressive strength, water absorption rate, and density. The data were analyzed using descriptive statistics such as mean and standard deviation. The results showed that all lightweight bricks had compressive strengths between 7.38 ? 0.42 to 12.68 ? 1.27 MPa. The means compressive strength of the sample with 10 wt% of rice husk ash (12.68?1.27 MPa) was approximately the same as the control unit (13.28 ? 0.42 MPa), water absorption rate 15.4 ? 1.48%, density 1.47 ? 0.01 kg/m3, and the production cost of materials is approximately 16.47 baht (137.2 baht/m2). Therefore, rice husk ash can be used as a raw material for producing lightweight bricks, and the bricks with a 10 wt% of rice husk ash can be used to produce bricks for masonry walls or indoor partitions that are not part that supports the weight of the building structure. |
