摘 要:将矿物掺合料分别掺入钢渣混凝土中,与普通混凝土抗压强度及抗侵蚀性能进行比较,从而得出一种适用于钢渣轨枕混凝土的配合比。结果表明,标准养护210d时,钢渣混凝土强度均超过普通混凝土;在180d硫酸盐和镁盐侵蚀下,普通混凝土与钢渣混凝土抗侵蚀系数均大于0.8,抗侵蚀性能良好。当粉煤灰、矿渣粉和钢渣粉三者复掺时,钢渣混凝土的后期抗压强度和抗侵蚀能力均表现最佳。
Abstract: The mineral admixtures are mixed into the steel slag concrete respectively, compared with the compressive strength and the corrosion resistance of the common concrete, a kind of mixture ratio suitable for the steel slag sleeper concrete is obtained. The results show that at the standard curing 210 days, steel slag concrete strength is better than ordinary concrete. Under 180 days sulfate and magnesium salt erosion condition, ordinary concrete and steel slag concrete corrosion resistance coefficients are both greater than 0.8, with good anti-erosion performance. When the fly ash, slag powder and steel slag powder are mixed together, the later compressive strength and corrosion resistance of steel slag concrete are the best.
