THE USE OF POLYMERS IN CONCRETE REPAIR

Although whenever practicable concrete repairs should be carried out with cementitious systems, there are cases where repair compositions containing polymers, either as admixtures or as high-strength binders, are more appropriate. The application of polymers in concrete repair principally refer to two main types of materials: (1) polymers used to modify cementitious systems, and (2) reactive thermosetting resins based on epoxy, polyester and acrylic systems. The use of these materials in various applications is described and also details are given of repair methods employed on concrete structures. (TRRL)
