STUDY OF THE IMPREGNATION OF CONCRETE WITH POLYMERIZATION RESINS. PART 1: DEVELOPMENT OF IMPREGNATION TECHNIQUES

ETUDE DE L'IMPREGNATION DU BETON PAR LES RESINES POLYMERISABLES - PREMIERE PARTIE: ELABORATION DES TECHNIQUES D'IMPREGNATION

The presence of voids in concrete causes a weakness in the material. A solution to this problem consists in introducing in the voids accessible a material with high tensile strength. The treatment is carried out by injecting in the capillaries, previously emptied of water and air, an organic resin in the form of a low-viscosity liquid. This resin initially takes the form of free molecules and is then called; monomer. Once a catalyzer has been added and various treatments (such as thermocatalysis or gamma-ray radiation) applied, the different molecules adhere to each other to form long chains. This phenomenon results in the hardening of the resin, which is then called: polymer. Concrete treated with the latter is called: impregnated concrete. The author discusses impregnation techniques, general characteristics of the different resins used, test methods, optimization of the different phases of total or partial impregnation, and the results obtained with different resins. /TRRL/
