This study is a preliminary test for children's game wall, in which recycled scrap iron containers and other scrap iron, crushed, paint, and other procedures are mixed with cement concrete to replace the aggregate. This follows the curing of cement-based iron sand concrete magnetic adsorption properties. Because, compressive strength is important for concrete, this study determines the compressive strength of concrete that contains iron sand, which can be adsorbed by magnets, by using recycled scrap iron containers and other scrap iron. The test variables include 7-day, 14-day, and 28-day compressive strength. The water to cement (W/C) ratio is 0.5, and the iron sand replacement rates run from 0% to 60%. The result shows that when 10% of iron sand is used as a substitute to find aggregates, it has the highest compressive strength and has magnetic adsorption. |
