摘要
采用加速模拟试验方法,研究了水工混凝土在一定流速软水作用下的表面接触溶蚀特性,并且利用试验数据,对水工混凝土的表面接触溶蚀耐久性进行了评价.溶蚀砂浆表面的微观测试和孔结构测试结果表明,随着表面接触溶蚀时间的延长,混凝土或砂浆中溶出的物质越来越多;掺入粉煤灰,水泥混凝土溶蚀量增大.
Using accelerated simulation test the characteristic of surface contact dissolution in hydraulic concrete under attack by flowing soft water in certain rate was studied. The resistance to dissolution was evaluated by use of experimental data. Combining microstructure and pore structure test of surface layer author thinks that ions of dissolution from surface of mortar or concrete become more and more as the time of contact dissolution increases and the amount of dissolution increases if fly ash is added in the concrete.
