炉石活性粉混凝土静动态韧性及耐久性

Static-Dynamic Toughness and Durability of Reactive Powder Concrete Containing Blast Furnace Slag

本研究将活性粉混凝土中的硅灰利用水淬炉石粉取代,探讨不同炉石粉取代量添加钢纤维含量1%、2% 抗压强度变化,找出炉石取代后抗压强度可达到150MPa最佳配比,并控制流度值在200-250 m m 避免添加钢纤维有沉淀的现象发生.试验结果比较150MPa炉石活性粉混凝土的静动态韧性、及微观晶体结构的差异性.

In this study,the active powder concrete silica fume powder substituted with water quenching furnace,furnace explore different substituents powder added in an amount of steel fiber content of 1%,2% compressive strength,compressive strength looking baked stone,after replacing up to 150 MPa best ratio,and controls the flow value at 200-250 mm avoid adding steel fibers precipitation phenomenon. Test results compare 150 MPa furnace slag powder concrete activity of static and dynamic toughness and microstructure differences crystal structure.
