In today’s world, the issue of how to repair damaged concrete is becoming more and more important in order to extend the service life of concrete structures. Chemical and physical attacks are very common and often occur together with poor quality concrete that inevitably cause major damage.
A special system for concrete repair has been studied many years ago and it has been used in a real construction site for the reparation of the concrete. This system is based on regular concrete repair structural mortars (thixotropic or fluid) shrinkage-compensated that are sprayed on the vertical surface or, when possible, pumped directly into the formwork. These mortars are normally used to replace the concrete cover and/or to reinforce the section of the concrete structures. In this system the mortars are protected by using a polymer-modified cementitious elastic mortar in order to improve durability and service life of concrete structures.
Polymer-modified cementitious elastic membrane plays a very important role and for this reason it is tested against the main important dangerous substances. This paper shows the main properties of this protective membrane and reports a case history of its efficiency for the reparation of an important bridge.
