混杂纤维混凝土高温抗压强度试验研究OA
Experimental Study on High Temperature Compressive Strength of Hybrid Fiber Concrete
文中以聚丙烯纤维和钢纤维为掺入对象,研究了不同种类纤维与纤维体积率掺入对不同基体强度混凝土高温抗压性能产生的影响,结果显示,200℃高温处理时混杂纤维混凝土抗压强度有所降低,400℃时抗压强度回升且高于常温,进一步提高温度后抗压强度快速降低;采用C60混凝土掺入0.1%聚丙烯纤维和1.0%钢纤维制备的混凝土试件,具有良好的高温后抗压强度.
Taking polypropylene fiber and steel fiber as the additive objects,the effects of different types of fiber and fiber volume ratio on the high temperature compressive properties of concrete with different matrix strength were studied.The results show that:The compressive strength of hybrid fiber concrete decreases at 200℃,rises at 400℃and is higher than normal temperature,and decreases rapidly when the temperature is further increased.The hybrid c…查看全部>>
