摘要

For new construction materials the development of testing methods, which allow a rating of, their durability on base of accelerated ageing investigations, is an important aim. The investigation of the durability behaviour of composite materials is to a high degree combined with the investigation of the bond behaviour between the glass roving and the concrete. The bond behaviour of textile reinforced concrete is influenced by the alkalinity of the pore water, which generally leads to decreasing tensile strength values of the glass roving. Furthermore hydration products can lead to a mechanical damage of the glass rovings. Hydra-tion products grow into the glass roving and reduce the elasticity of the roving. The following report presents a combined testing method, which allows to investigate the changes of bond and strength characteristics of the system roving/concrete caused by climatic stress. It is necessary to distinguish between a variation of the tensile strength of rovings in the concrete and a variation of the bond between the two materials. The presented experimental results show the interaction of both parameters.
