Paper Title:
Study on a New Adhesive of Concrete Cracks Repairing
  Abstract

A new class of structural glue called permeant adhesive is introduced for repairing concrete cracks. The viscosity and strength of the permeant adhesive are tested, respectively. Then the durability of concrete such as sulphate attack, freeze-thaw resistance and impermeability of the repaired concrete are discussed. It is shown that temperature and reactive diluent are important factors in viscosity of the permeant adhesive. Curing agent and reactive diluent are important factors in strength. Hereby, the optimum proportion is A: B=1:0.5, and the amount of reactive diluent is 10% to 15%. The strength of the repaired concrete which is immersed in sulphate increases 3% to 26.2%, while the freeze-thaw resistance and impermeability of the repaired concrete are better. The above provide the theoretic and experiment foundation for simpling the pressure grouting technique of the concrete repaired and the application on the permeant adhesive.
