Construction method of filling reinforcing joint
The invention provides a construction method of filling a reinforcing joint, in particular a reinforcing joint filling construction method of filling cement mortar into a reinforcing joint. The cement mortar is obtained by adding water into reinforcing joint materials containing cement, expanding agent, micro powder ash, water reducing agent and fine aggregate, and stirring for more than two minutes by an artificial blender, a high speed mortar mixer or a forced mixer. The characteristics are that the expanding agent is a calcium aluminoferrite expanding agent; the micro powder ash is Silica micro powder with a silicon dioxide SiO2 percentage content greater than 95.2%, and a hydrogen ion concentration acidic region lower than pH 6.5; the water reducing agent is a polycarboxylate-type water reducing agent; the fine aggregate is a heavyweight aggregate with a largest grain size of 2mm, and a density greater than 3.og/cm3.
