地下结构混凝土渗透特性试验研究
Experimental research on concrete permeability of underground structure
摘要
Abstract
In accordance with bearing water pressure and cracking, using test system made up by self-made concrete sample mould, self-made controlled cracking device, self-made controlled water pressure device, and crack width measuring instrument, experiments for permeability of cracked concrete are carried out under the conditions of different water pressures, concentrations of chloride ion, crack widths and soaking times. The experiment results show that chloride ion content of concrete increases significantly with the increasing of water pressure when the other experimental conditions are same; and the migration laws are different; and crack width threshold which is independent of water pressure controls the migration of chloride ion. This method can provide a reference for similar study.关键词
