摘　　要：研究了矿粉掺量对混凝土力学性能、耐久性等相关性能的影响。试验结果表明,在相同水灰比条件下,掺入矿粉后混凝土7d及28d力学性能有所降低;抗渗性能得到了改善,但随着矿粉掺量的增加而有所降低;混凝土塑性收缩增大;抗氯离子渗透性能增强。The influences of dosages of slag powder on the mechanical property and durability of concrete are investigated.The experimental results show that with the same water-cement ratio,after adding slag powder,the 7 days and 28 days mechanical properties of concrete are certainly decreased,the impermeability of concrete is improved,however,the impermeability is a bit decreased according to the dosage of slag powder increasing,the plastic shrinkage of concrete is greater and the performance of chloride ions penetration resistance is better.
