“…This has been confirmed by many investigators, who found no evidence of fiber cross section reduction after ageing tests (Bentur, 1985;Cohen & Constantiner, 1985;Diamond, 1985;Jaras & Litherland, 1975). In 2001 Purnell offered a new approach claiming that the main cause of GRC weakening with time is the growth of flaws on the fiber surface.…”

Abstract. Glass fiber reinforced concrete (GRC) is used for 40 years to create world's most stunning and complex architectural elements due to its high mechanical properties, particularly flexural strength. Yet it is very important to note that any type of glass fibers in the concrete matrix are undergoing complex ageing processes, resulting to significant decrease of initial mechanical characteristics of this composite material under natural weathering conditions. Aspects of GRC durability are mainly dependent from the properties of fibers and interaction between them and concrete matrix. In this article, long term strength retention of this composite material is discussed, existing experimental data of weathering tests presented, and main corrosion mechanisms explained. Lack of knowledge about freeze-thaw resistance of glass fiber reinforced concrete is addressed. Finally, latest attempts of GRC durability improvement are reviewed, such as adding micro fillers, polymers to the concrete matrix and enhancing surface of fibers in Nano scale.

“…The development of the portlandite crystals in FSH samples can be explained by the presence of water in the pores of the samples. The water permits the Ca ++ ions diffusion towards the matrix and then the growth of the portlandite the solution in the paste is always saturated with Ca ++ ions and the voids are simply the free place for crystallization not only of portlandite but also of ettringite [28][29][30]. Portlandite peaks are weaker in the samples containing silica fume.…”

“…Especially, the research in Germany, Greece, Denmark, and France focusses on strengthening of RC structures. Strengthening for bending (Schladitz et al [28] and Weiland et al [29]) and shear (Brückner et al [30], Schladitz et al [31], Triantafillou and Papanicolaou [10], and Si Larbi et al [32]), confinement of columns (Bournas et al [33], Triantafillou et al [11], Ombres [34], and Ortlepp et al [35]), and enhancement of durability (Butler et al [36] and Michler [37]) are examples of the possible realizations of TRC strengthening. Retrofitting and strengthening of earthquake-damaged or rather vulnerable structures are other worthwhile applications.…”

“…However, these results can rarely be used for predicting the development length of textile mesh. Butler et al [36] performed experimental investigations on important mechanisms influencing the durability of the fibre-matrix bond in TRC using double-sided pullout test on slender notched specimens reinforced with a few multifilament AR glass yarns.…”

Natural resources can be conserved if we carefully maintain the building stock and indeed extend the useful economic life of buildings. One way to achieve this is to enhance load-bearing structures by repair, restoration, or strengthening. Such upgrading often involves applying a strengthening to existing concrete elements. Over the past decade, textile-reinforced concrete (TRC), encompassing a combination of fine-grained concrete and noncorrosive multiaxial textile fabrics, has emerged as a promising novel alternative for strengthening of conventional steel-reinforced concrete (RC) structures, offering enhanced load-bearing capacity with minimal weight and stiffness change. Although TRC has been extensively researched during the last two decades, the formalization of experimental methods and design standards is still in progress. Attempts to design for good load transfer are often hindered by lack of knowledge regarding bond behaviour. For instance, there are neither standard recommendations nor proofs regarding the required development length of textile fibres in TRC for practical applications up to now. e aim of this work was to provide a test specification, which gives a direct result for the development length (required for the anchorage of a reinforcement, also referred to as "anchorage length") of textile reinforcements in fine-grained concrete-quickly and easily. e aim of this paper was to present the test specification developed in a way that it is useful for the future work of other researchers as well as for construction engineers. Some selected experimental investigations with different textile reinforcements and different bonding properties were performed with the aim of showing the applicability of the proposed adaptive test specification. e results of these tests indicated that conventional AR glass and carbon fabrics without coating required large anchoring lengths. e tests further showed that an additional application of different kinds of coating to textile fabrics greatly increased the reinforcement's resistance to pullout. is is of special interest for carbon fibres, which have a substantially higher strength than AR glass fibres and different bond behaviour; that is, carbon fibres have, by nature, larger development lengths.
