Abstract

The paper presents the results of tests of natural and accelerated weathering for chosen polymer and cement-polymer materials used in repair and surface protection of reinforced concrete structures. The tests comprised: a) crack resistance of protective coatings, b) estimation of quality of compatibility of grouting materials with the concrete, c) tensile strength, tensile strain, Young’s tensile modulus of elasticity of coating and grouting materials and their adhesion in tension to the concrete. On the basis of the tests carried out, functional relations have been observed between weathering of materials in natural conditions and weathering in accelerated conditions. Experimental relationships were fixed enabling the forecast of durability of materials included in the tests, and also for other similar materials to those tested, for repair and protection of concrete in regard to binder type. The usability of grouting and coating materials was determined by defining to what extent and for how long it might be acceptable to allow the worsening of material properties used in repair and for the protection of concrete against corrosion.
