Textile Reinforced Concrete: Material, Modelling & Application Potential

Textile reinforced concrete (TRC) is a cementitious‐based material where reinforcement consists of high‐strength noncorrosive textile fabrics. Due to the use of a noncorrosive reinforcement, cover requirements can be limited to minimum static values and the amount of clinker in the cement can also be notably reduced. In addition, the simplicity to arrange the fabrics in complex formworks makes the material suited for thin shells or folded structures (typically with thicknesses ranging 10–20 mm). Due to the savings in material and to the lower amounts of clinker used for its production, TRC has a higher sustainable potential than conventional reinforced concrete, with a significantly lower CO2 footprint.

1:10:25 Questions | Patrick Valeri & Vladyslav Shekhovtsov
1:10:31 What is the durability of textile in your motor?
1:13:04 What about the role of basalt fiber in various forms as reinforcement material, especially BFRP bars?
1:13:56 What are the mains applications of the textile RC and in what cases?
1:15:20 For what type of structures we can use this reinforcement due to low fire resistance in comparison with ordinary steel?
1:16:13 What a tensile strength of textile was used in calculation of construction for ultimate limit state. Or maybe calculation used a non-linear calculation modeling?
1:17:25 What about the cost of the TRC versus the cost of the normal reinforced concrete or steel structure?
1:18:42 Do you have any suggestions on the pull-out test method of TRC, single-sided or double-sided?
1:19:43 where did you get the textile?
1:20:50 What kind of shear transfer mechanism that a TRC beam member has? Does it have any concrete contribution (compression zone + aggregate interlock) like normal RC beam or is it purely contributed from the tensile strength of the textile reinforcement that serves as stirrups?
1:22:37 Is the reinforcement from Solidian?
1:23:15 Is it possible to try this technology in prestressed concrete girder ?
1:24:03 Are there any limitations about the spacing of the textile? Also in relation to possible delamination problems?
1:25:51 Do you consider TRC as FRCM ?
1:27:00 Have you been performed any FE Analysis and validated those models with experimental values? Did you worked on Fracture Mechanics?
1:27:55 Is temperature play any role for textile reinforcement?
1:29:55 Have you tried this on a post-tensioned concrete i girder for a highway bridge?
1:30:22 Also, trying this on a prestressed concrete hollow circular pile?
1:31:18 Can the TRC used for strengthening of existing concrete elements?
1:33:35 In your analytical bond-lag model, how do you determine the cross-sectional area (or the diameter) of your sleeve and core? I mean, is there a physical thickness of each component or did you assume the thickness?
1:35:32 With respect to the safety concept of TRC structures, how did you assess the robustness of your structures? Do the members show any measurable deflection or cracking before failure that you could define as a monitoring criterion?
1:38:48 What does the crack reach before textile would broke?
1:40:44 What are your thoughts on integration of Textile reinforcement with non-load bearing 3D concrete printed facade/partition wall to improve flexural strength of the wall element? Do you think it will be beneficial from any perspective at all?
1:42:32 What about common work of reinforcement of your textile and concrete?
1:46:00 Do you think textile can be the primary reinforcement for a main structure?

A bridge between research and practice.

The fib, Fédération internationale du béton, is a not-for-profit association formed by 42 national member groups and approximately 1000 corporate and individual members. The fib’s mission is to develop at an international level the study of scientific and practical matters capable of advancing the technical, economic, aesthetic and environmental performance of concrete construction.

The knowledge developed and shared by the fib (fib Bulletins, fib events, fib workshops, fib courses, etc.) is entirely the result of the volunteer work provided by the fib members.

The fib was formed in 1998 by the merger of the Euro-International Committee for Concrete (the CEB) and the International Federation for Pre-stressing (the FIP). These predecessor organizations existed independently since 1953 and 1952, respectively.
