Abstract [en]

Conventional steel reinforced concrete is one of the most commonly used building materials,yet it has shortcomings in terms of weight, thick concrete covers, and durability namely corrosion of thereinforcement. Textile Reinforced Concrete (TRC), a combination of fine-grained concrete and noncorrosivefibre grids, has emerged as a promising alternative; corrosion is no longer an issue and muchthinner and light-weight elements can be designed. Although TRC has been expansively researched,unknowns pertaining to the long-term durability arise when attempting to implement such innovativebuilding materials. The aim of this article is to study the effect of accelerated aging on the tensile strengthof various textile fibre grids according to ISO 10406-1 [1]. Carbon, basalt and alkali-resistant (AR) glassfibre grids were immersed into high alkali environment and elevated temperature for 30 days. Directtensile tests were conducted before and after aging to observe the degree of stiffness and tensile strengthloss. After aging, the carbon fibre grids were marked by an increase in both tensile strength and stiffness,while AR-glass and basalt were degraded to the extent that tensile tests could not be conducted.Specimens were therefore exposed to alternative conditions to identify the governing degradation factor.
