Abstract: Steel reinforced concrete is the most popular material for modern building solutions. One of its well-known issues is the high susceptibility of steel to corrosion. In recent times, research has focused on the replacement of steel rebars in reinforced concrete. The use of textiles has gained a strong interest in this context. These textiles can be impregnated into mortars or concrete and are not sensitive to corrosion. However, for practical applications, an analysis of their durability performance and long term behavior is necessary.In this paper textile reinforced cementitious composites (TRCs) with a low fiber volume fraction are studied. To study their long term behavior, the specimens were aged by performing heat- rain and freeze thaw cycles, according to EN 12467. After ageing, the structural performance of the aged specimens was compared to reference specimens by means of a uniaxial tensile test. To compare the structural behavior quantitively, a focus was placed on the mechanical properties which have the largest influence on the design requirements, namely the first cracking strength, the ultimate strength, and the stiffness in the linear and final stage of the stress-strain curve. A substantial decrease of up to 80% was experienced by all properties due to the environmental loading conditions.
