矿用喷射混凝土碳化深度研究及改善分析

Study and Improvement Analysis of Carbonation Depth of Mine Shotcrete

在认知碳化规律的基础上,对矿用喷射混凝土进行了优化设计并进行实验,分析了主要环境因素对碳化深度的影响,利用实验数据拟合得到湿喷混凝土的碳化深度方程,最后设计了减水剂掺量实验寻求减小碳化深度的方法,结果表明减水剂使喷射混凝土的抗碳化能力有较明显提升。

On the basis of knowing the law of concrete carbonation, did the optimal design of wet-spraying concrete and the experiment,and analyze the meaning between many elements and carbonationdepth. The carbonation depth equation of wet-spraying, concrete was obtained by tilting the test data.Seek the way of reducing the carbonation depth by the way of dosage admixture experiments. Theresults show that water-reducing admixture lets the carbonation ability of wet-spraying concrete obviouslyimprove.
