摘   要：在水胶比相同的条件下，制备了纯水泥混凝土、分别掺加30%和40%钢铁渣粉A（矿渣∶钢渣=7∶3）的混凝土、分别掺加30%和40%钢铁渣粉B（矿渣∶钢渣=6∶4）的混凝土，并经蒸汽养护后，测定了不同蒸养混凝土的抗压强度、抗氯离子渗透性、抗碳化性和抗硫酸盐侵蚀性。结果表明，掺加钢铁渣粉能提高混凝土后期的抗压强度；掺加钢铁渣粉A的混凝土的抗压强度高于掺加钢铁渣粉B的混凝土的抗压强度；掺加钢铁渣粉能提高混凝土28d的抗氯离子渗透性，其中掺加40%钢铁渣粉A能明显提高混凝土90d的抗氯离子渗透性；掺加钢铁渣粉对混凝土的抗碳化性能影响很小；掺加钢铁渣粉能明显提高混凝土的抗硫酸盐侵蚀性。

Abstract: The pure cement concrete is prepared by 30% and 40% ground iron and steel slag A (GGBS: steel slag ratio is 7:3), and concretes with 30% and 40% ground iron and steel slag B (GGBS∶steel slag ratio is 6∶4) under the same water-to-binder ratio, the compressive strength, resistance to chloride ion penetration, anti-carbonation and anti-sulfate attack properties of steam-cured concretes were determined. The results show that, adding ground iron and steel slag can improve the late-age compressive strength of concrete, the compressive strength of concrete with ground iron and steel slag A is higher than that of the concrete with ground iron and steel slag B. The resistance to chloride ion penetration of concrete is improved by adding ground iron and steel slag at the age of 28 days. The resistance to chloride ion penetration of concrete is improved by adding 40% ground iron and steel slag A at the age of 90 days. The addition of ground iron and steel slag has little effects on the anti-carbonation properties of concretes, which can improve the anti-sulfate attack property of concrete with ground iron and steel slag.
