Abstract: With the development of industry, human’s demand for steel is on the rise. The phenomenon brings large of quantity steel slag which takes up abundant land and causes a lot of environmental pollution problems whereupon it. To deal with this situation, there is a great need to make comprehensive use of steel slag to recycle the waste into the valuable resource.
Through the analysis of the rotating furnace slag of Shaanxi Longmen Iron & Steel (Group) Enterprise Co., Ltd, this paper selects five different contents of steel slag to replace the same volume fraction of sand for the preparation of the mortar. The properties of interest include consistency and density of fresh mortar, as well as the compressive strength, frost resistance and shrinkage resistance of hardened mortars. The microstructure of hardened mortar is also analyzed with a scanning electronic microscope in this paper. As a result of the experiment, it is demonstrated that the mortar’s microstructure characteristics conform with its macro property. With the application of the appropriate mixture proportioning of mortar as well as the utilization of the local steel slag, sand and cement of Shaanxi province, the steel slag mortar confected with two volumes of steel slag and three volumes of sand meets all requirements on the physical and mechanical property and durability.
