Abstract:
There is a great demand in the world for low-cost and functional pipeline systems due to the renovation
requirements of pipes in use and the continuous development of new settlements. Previously used pipeline systems
made of steel reinforced concrete are economical and sufficiently resistant. However, due to the corrodibility of steel
reinforcement and to enable sufficient crack reduction, large wall thicknesses and thus heavy constructions are
required. Textile reinforced concrete (TRC) eliminates these disadvantages by enabling the production of light and
thin-walled structures.
The aim of this research is the development of a concept for the realization of smart pipes made of sensory TRC by
using the advantages of lightweight, thin-walled structures, focusing on the production process. Based on different
warp knitted textile variations with different coating concentrations, preliminary tests were carried out using the fourpoint bending test. As a result of the preliminary tests, the textile variation of counterlaid tricot with a maximum
coating concentration was selected as a suitable reinforcing material for the concept development. Concepts for the
production of smart TRC pipes are developed accordingly. As a result, a casting mold and process were created which
allowed a production with reduced diameter and depth of pores and concentric positioning of the reinforcement
structure.
