炭黑替代碳纤维对混凝土电、热及力学性能的影响

摘要

The effects of carbon fiber content on the electrical and mechanical properties of concrete were studied and the effects of car-bon black instead of 10%,20%,30%,40% and 50% carbon fibers on the electrical thermal,and mechanical properties of concrete were al-so investigated.The optimal replacement rate is 30% viewing the electrical properties,electro-thermal properties and mechanical properties of the concrete.At the same time,the effect of different input voltages and curing time on concrete resistivity were tested.%研究了碳纤维的掺量对混凝土电性能及力学性能的影响,并探讨了用10%、20%、30%、40%、50%炭黑替代碳纤维对混凝土电、热及力学性能的影响,从混凝土的导电性能、力学性能及电热性能来看最优替代率为30%.同时测试了不同输入电压、龄期对混凝土电阻率的影响.
