摘要
本文介绍了矿粉、粉煤灰在高标号混凝土中的试验和应用情况,并分析了这些胶结料对混凝土性能的影响,说明采用矿粉取代部分水泥,使混凝土拌合物性能进一步改善、保证中长期力学性能、提高抗渗性能。
This paper describes the test and application of mineral powder and fly ash in high-grade concrete,analyzes the impact of these cement material on the properties of concrete,and shows that using mineral powder to replace part of the cement can further improve the performance of concrete mixture and ensure the long-term mechanical properties and improve impermeability.
