Epoxy floor layers

Comparison of obtained curves indicates that in the case of the cement-polymer composite modified using of SBR there is only small increase of strength capacity and deformability after repair using of the epoxy and the polymer PT. This kind of repair restores strength ability of cracked concrete and also of the cracked repair thin layer made of cement-polymer composites but do not protects a concrete floor against over-ultimate deformations, overcoming the ultimate strain angle (y < 0.5 %) of concretes and cement-polymer composites (Fig. 14).

Another important application of reactive resins is the production of resin-bonded screeds that, by virtue of their high mechanical and chemical stability, are used, for example, for industrial floors. One particular problem is the bonding of old concrete to new concrete, where peeling occurs because of the shrinkage of the new concrete layer. By applying intermediate layers of a suitable epoxy resin mortar, it is possible to establish permanent bonds with strengths greater than that of the concrete.
