Development of Sustainable High-Strength Bricks Using Rice Husk Ash and Coconut Fiber Reinforcement for Affordable Housing Applications
Description
This study will employ an experimental research design to develop and evaluate sustainable high- strength bricks made from rice husk ash and coconut fiber reinforcement. The experimental approach is appropriate because it allows the researcher to systematically manipulate the proportions of rice husk ash and coconut fiber and determine their effects on the physical and mechanical properties of the bricks. Different treatment groups with varying material compositions will be prepared, manufactured, and subjected to standardized laboratory tests, including compressive strength, water absorption, density, and durability assessments. The results will be compared with those of conventional bricks to identify the optimal mixture that provides the best balance of strength, sustainability, and affordability for housing applications. This design enables the establishment of cause-and-effect relationships between the independent variables (rice husk ash and coconut fiber content) and the dependent variables (brick performance characteristics)..

Steps to reproduce
The data collection process will begin with the acquisition of the necessary raw materials, including rice husks, coconut fibers, Portland cement, fine sand, and water from reliable sources. The rice husks will undergo controlled burning to produce rice husk ash (RHA), which will then be cooled, sieved, and processed to achieve a fine and uniform particle size suitable for brick production. Meanwhile, the coconut fibers will be cleaned to remove impurities, cut into appropriate lengths, and treated as necessary to improve their bonding characteristics within the brick matrix. After the preparation of all materials, the designated proportions of rice husk ash, coconut fiber, cement, sand, and water will be mixed thoroughly to ensure homogeneity. The resulting mixtures will then be molded into standard brick specimens according to the treatment groups established in the study. The molded bricks will be cured under controlled conditions for twenty-eight (28) days to allow proper hydration and strength development. Following the curing period, the brick samples will be subjected to laboratory testing, including compressive strength, water absorption, density, and durability assessments, using standardized testing procedures. The data generated from these tests will be systematically recorded, organized, and prepared for statistical analysis to determine the effectiveness of rice husk ash and coconut fiber as sustainable materials for high-strength brick production.
