The use of steel slag as aggregate in concrete is one environmentally friendly method to reduce the detrimental consequences of the depletion of natural mineral resources. The behavior of steel slag sand concrete (SSC) under compression is examined in this paper. A set of cube tests under compression are reported, with the results evaluated. The experiments used SSCs integrated with steel slag at volume substitutions of 0, 10, 20, 30, and 40% for fine aggregate. The findings indicate that concrete's compressive strengths can be raised by including steel slag as fine aggregate. The strength of compression of SSC first rises as the amount of steel slag increases when loading is applied. Compressive strength falls once the ideal percentage of steel slag is added. Water permeability, acid attack, and rapid chloride penetration test are conducted for the durability test. The addition of steel slag to concrete increases the material's ductility, durability, and resistance to cracking. To achieve enhanced performance for SSC under compression, 20% of steel slag should be used as fine aggregate.
