INFLUENCES OF DOSAGE OF ADJUSTING MATERIALS ON RECONSTRUCTED STEEL SLAG

摘要：

In this contribution, the influences of the additives of calcic, silicic and aluminiummaterials on the reconstructed steel slag were investigated by the orthogonal experiment. Inthe experimental program, the optimum dosage of additives was determined. The compositionof mineral phase was analyzed by XRD and the appearance of minerals was observed bySEM. The results show that the optimum dosages of additives are, the calcic material is8.85％, the silicic material is 2.48％ and the aluminium material is 2.79％. Because morecementitious minerals the reconstructed steel slag has better cementitious property. When thecementitious minerals react with water, more hydration products would be produced, theharden paste would become denser, and the strength of harden paste would be higher thansteel slag.
