水工碾压混凝土渗透溶蚀特性研究

研究了在软水渗透的情况下，水工碾压混凝土的渗透溶蚀特性。首先通过对水泥净浆和水泥砂浆的渗透溶蚀试验，得出水泥基材料中渗透溶蚀的主要途径是硬化水泥浆体。其次通过对不同粉煤灰掺量、不同外加剂掺量的水工碾压混凝土的渗透溶蚀试验，得出影响混凝土渗透溶蚀性能的最重要因素是混凝土的渗透系数，并在此基础上探讨了渗透溶蚀的稳定性及耐久性。

Research on leakage dissolution of hydraulic roller compacted concrete (RCC)

The leakage dissolution performances of hydraulic RCC under the permeation of soft water was investigated. First, by the leakage dissolution experiments of hydrated cement paste and mortar, this research acquires the result that the main leakage dissolution part of cement-based materials is hydrated cement paste. Second, through the leakage dissolution experiments of hydraulic roller compacted concrete with different contents of fly ash or additive, it is concluded that the most important factor affecting the leakage dissolution performances of hydraulic RCC is its permeation coefficient. Furthermore, this paper discusses the stability and durability of leakage dissolution of hydraulic RCC.
