碳纳米纤维混凝土防腐性能试验与检测

Test and Detection of Anti-corrosion Performance of Carbon Nanofiber Concrete

基于复合改性方法,提出改性碳纳米纤维高耐久性混凝土,以解决污水环境中材料耐久性不足的问题。实验结果表明,纤维混凝土的耐腐蚀性能得到改善,试件的强度保持率提高了6%。无机铝盐改性混凝土的效果显著提高,剩余强度为44.68 MPa,提高40%,强度保持率为26%,因此无机铝盐的效果更好。

Based on the composite modification method,modified carbon nanofiber high-durability concrete is proposed to solve the problem of insufficient material durability in sewage environments.Experimental results show that the corrosion resistance of fiber concrete is improved,and the strength retention rate of the specimen is increased by 6%.The effect of inorganic aluminum salt modified concrete is significantly improved.The residual strength is 44.68 MPa,an increase of 40%,and the strength retention rate is 26%.Therefore,the effect of inorganic aluminum salt is better.
