为提高钢渣的利用率,利用钢渣与矿渣作掺合料、钢渣作骨料制备成钢渣砂替代碎石,制备钢渣高强混凝土。通过正交试验研究了水灰比、砂率、钢渣砂掺量、掺合料掺量4种因素对钢渣混凝土工作性能、强度的影响,得出了钢渣混凝土最适宜配合比。采用电通量法研究了最适宜配比钢渣混凝土的氯离子渗透性,其较基准混凝土要好。通过SEM照片对最适宜配合比钢渣混凝土3、28 d的微观结构进行了分析,水化产物较基准混凝土密实。钢渣、矿渣等应用到混凝土中不仅具有环保节能的效果,还能改善混凝土的性能,具有良好的经济和社会效益。

In order to improve the utilization of steel slag,steel slag and slag as admixture,and as aggregate, a kind of steel slag sand substitute is prepared for gravel for steel slag high-strength concrete.In orthogonal ex-periments,the factors affecting strength and working performance of concrete including water cement ratio, sand-ratio,the dosage of steel slag sand,the dosage of admixture are studied.So suitable proportion of steel slag concrete is given.Through the use of electric flux,chloride ion permeability of the steel slag concrete with proper proportion is analyzed and proved to be better than that of base concrete.From SEM photos,the micro-structure of steel slag concrete at 3 days and 28 days are analyzed,and the extent of compactness is proved to be superior to base concrete.The application of steel slag and slag to the concrete can not only protect environ-ment and save energy,but also improve the comcrete performance,with good economic and social benefits.
