Utilizing Aggregates Materials of Expanded Polystyrene, Gravel, and Wood Sawdust in the Development of Bricks

Abstract

This study aims to develop eco-bricks using expanded polystyrene, gravel, and wood sawdust. The modern brick industry has a problem finding materials to make bricks due to industrialization, economic development, and loss of natural resources such as clay, which is the primary material in making bricks. The researchers devised a solution to this problem by providing alternative bricks, eco-brick. Experimental and observation methods were used. The researchers first developed a theory regarding the bricks that were made. Second, the researchers observed the bricks while they were being tested. The third step in the research process is the data collection phase. Based on the result of the experiment, expanded polystyrene, wood sawdust, and gravel contribute generously to the production of bricks because of their properties. Expanded polystyrene is a suitable adhesive that will hold all the ingredients together, and it has low moisture absorption and tolerance to water to be absorbed. Wood sawdust is suitable for filling the Eco-Bricks and adds a texture to the expanded polystyrene when mixed. The gravel gives strength to the Eco-Bricks and makes it more durable. The experimental results have shown that bricks made from expanded polystyrene, wood sawdust, and gravel have less water absorption and good durability, making them suitable for use in construction. While it's cheaper than ordinary bricks, the durability and water absorption of the Eco-Bricks have surpassed it. Eco-Bricks have the potential to reduce the environmental impact of ordinary brick-making methods. The extraction and processing of raw materials such as clay and sand to make ordinary bricks can significantly impact the environment. By using expanded polystyrene, wood sawdust and gravel is a better alternative than using clay and sand for making brick. In the end, the development of bricks using these materials can also create new job opportunities and promote economic growth, particularly in areas where these materials are abundant.
