| description | Many countries use crushed stone and crushed sand as the aggregate for concrete. However, a large amount of crushed stone powder is produced as by-products in the manufacturing process. Unless effective utilization of crushed stone powder is considered, it is not a sufficient measure in terms of sustainability. In this study, the properties of concrete using crushed stone powders with different specific surface areas are investigated. As the results, a strong correlation was found between the unit water content of concrete and the total surface area of the crushed stone powder contained in the concrete. Furthermore, it was concluded that the correlation between the strength index, the CO2 index, and the virgin resource index of concrete using crushed stone powder depends on the types of crushed stone powder and crushed sand. |
