Abstract
The basic mechanical properties of steel slag concrete with waste thermal steel slag instead of the coarse and fine aggregates in concrete are studied and compared with the mechanical properties of ordinary concrete. The test results show that the addition of steel slag as coarse aggregate will enhance the compressive strength and flexural strength of concrete, and it will improve with the increase in the steel slag content. When steel slag is used as fine aggregate, the compressive strength of the steel slag concrete subjected to first increases and then decreases with increase in the steel slag sand content. To obtain better performance for the steel slag concrete, the suggested optimum content of steel slag sand as fine aggregate is 50%. Within. The addition of steel slag as fine aggregate can improve the flexural strength of concrete, and the flexural strength increases with the increase of the addition of steel slag sand. The steel slag concrete with the highest strength can be obtained when 100% of steel slag replaces the concrete aggregate, and the steel slag has good basic mechanical properties for the application of road engineering.
