“…After hardening of the concrete, the stay-in-place formwork gets an additional structural function and acts as a (partial) tensile reinforcement of the final concrete structure. The structural capacity of stay-in-place formwork in textile reinforced concrete (TRC) was already demonstrated for beam elements in Brameshuber et al (2004), Papantoniou and Papanicolaou (2008), Papanicolaou and Papantoniou (2010) and at our university for the used composite GFTR-IPC in Verbruggen et al (2013) and De Sutter et al (2014). Both materials show similar results as stay-in-place formwork because the material properties are also very similar.…”

This article presents the structural evaluation of textile reinforced cement composite elements as formwork and reinforcement for concrete shells. Different shell geometries of 10 m span and a height between 2.5 and 5 m are examined. On one hand, the minimum thickness of the composite element functioning as formwork for these shells is determined when supported with a different number of supports and for different concrete sections. On the other hand, the minimum thickness of the composite functioning as reinforcement is calculated to withstand the occurring maximum bending moment. For shells with a 10 to 15 mm concrete section, a minimum composite formwork of 5-6 mm is needed to carry the load of the cast concrete, while the minimum composite reinforcement needed to withstand the maximum occurring bending moment equals 2-3 mm. Conclusively, this preliminary numerical study demonstrates the structural potential of textile reinforced cement composite stay-in-place formwork for concrete shells and indicates the dominance of the casting stage over the final stage. More specifically, local buckling of the formwork is the determining factor and should drive future work towards this issue.

“…In the case of strengthening of RC structures using TRC significant improvement in ultimate load capacity of existing structures can be achieved, while its application is simple and can be applied in any complex shape [21][22][23]. The addition of short fibers in the matrix of TRC is also studied by several researchers and found that the hybridization of short polymeric fibers with textile have positive effects on various properties of TRC-e.g., increase in ultimate tensile strength of TRC, reducing the crack width in TRC, etc.…”

Textile reinforced mortar or concrete, a thin cementitious composite reinforced by non-corrosive polymer textile fabric, was developed and has been researched for its role on repair and strengthening of reinforced concrete (RC) structures. Due to embedment of polymeric textile fabric inside the cementitious matrix, many researchers argued the superiority of this technology than the externally bonded fiber reinforced polymer (FRP) sheet in RC in terms of prevention of debonding of FRP and durability in fire. However, due to use of cement rich matrix the existing development of textile reinforced concrete (TRC) need to be more environmental friendly by replacing cement based binder with geopolymeric binder. This paper presents a first study on the flexural behavior of alkali resistant glass fiber textile reinforced geopolymer (TRG). In this study, two types of geopolymer binder is considered. One is fly ash based heat cured geopolymer and the other is fly ash/slag blended ambient air cured geopolymer binder. Both geopolymer types are considered in the TRG and the results are benchmarked with the current cement based TRC. The effect of short polyvinyl alcohol (PVA) fiber as hybrid reinforced with alkali-resistant (AR) glass fiber textile on the flexural behavior of above TRC and TRGs is also studied. Results show deflection hardening behavior of both TRGs with higher flexural strength in heat cured TRG and higher deflection capacity at peak load in ambient air cured TRG. The increase in PVA fiber volume fraction from 1% to 1.5% did not show any improvement in flexural strength of both TRGs although TRC showed good improvement. In the case of deflection at peak load, an opposite phenomenon is observed where the deflection at peak load in both TRGs is increased due to increase in PVA fiber volume fractions.

“…In the past studies, the development of stay-in-place formwork using TRC has been conducted around horizontal members such as slabs and beams [4,5,6,7]. Recently, experimental works on the performance of TRC stay-in-place formwork applied for a vertical member such as columns [8,9] and an asymmetric shell structure [10] have also been performed. Existing studies have demonstrated that the structural performance of a column using TRC is superior to that of a conventional RC column through the experimental test of specimens.…”

Recent earthquakes at Pohang in Korea have caused significant damages to existing reinforced concrete (RC) structures. Particularly, piloti columns of RC structures suffered considerable damages. The objective of this research is to review the feasibility of an innovative stay-in-place formwork method using the Textile Reinforced Concrete (TRC) for RC columns in order to improve seismic performance and reliability. The scope of the study includes 1) a development of a concept for TRC stay-in-place form for RC columns, and 2) designing and manufacturing of TRC form modules. It is expected that structural damage of the property, human injuries or loss of life caused by future earthquakes can be reduced by improving the seismic performance using TRC sitein-place participating form, which can also save the social cost for the recovery from the disaster.
