隧道用高抗渗耐蚀混凝土的试验研究

Test Study on Highly Impermeable/Erosion-proof Concrete Used in Tunnel Construion

结合隧道工程实例 ,介绍环境水为软水水质条件下 ,对混凝土掺入适量粉煤灰和减水剂以提高混凝土的抗渗耐蚀性能进行了试验研究和机理分析 ,给出了双掺配合比的确定以及混凝土的制备与使用效果。

With a tunnel which projects constructed in soft water environment, test study on the improvement of impermeability and erosion resistance of concrete with appropriate proportion of coal dust and water-reducing admixture was carried out. The analysis of the mechanism, determination of proportion of the two admixtures, preparation of concrete mixture as well as the effect of the application of such concrete were presented.
