摘要
对掺不同掺量碳纤维和硅灰的活性粉末混凝土的强度和温敏性进行检测,并分析其影响.结果表明:碳纤维能有效增加活性粉末混凝土的抗折强度和抗压强度;硅灰对其抗压强度有较好增强作用,对抗折强度增强效果不明显;碳纤维对其温敏性影响较小,而加入硅灰后其温敏性有较大增强。
The strength and temperature sensitivity of reactive powder concrete mixed with different amounts of carbon fiber and silica fume were tested and their effects were analyzed.The results show that carbon fiber can effectively increase the flexural strength and compressive strength of reactive powdered concrete.Silica fume has a better reinforcing effect on its compressive strength,and the effect of reinforcing the anti-folding strength is not obvious.The effect of carbon fiber on its temperature sensitivity is relatively small,and after adding silica fume,its temperature sensitivity has been greatly enhanced.
