Abstract

Graphical abstract: Highlights: Pipes using dry concrete FRCM are produced. Fabric reinforcement increase load bearing capacity of dry concrete pipes. Fabric reinforcement increase energy dissipation of mortar/concrete pipes. Proposed analytical method accurately (err < 16%) predicts cracking and maximum capacity. Abstract: Despite the well-known advantages of fabric-reinforced cementitious matrix (FRCM), few applications of this composite material have been proposed apart from structural strengthening. To exploit material corrosion resistance, seven FRCM pipes were produced with mortar and dry concrete matrixes. They were experimentally tested under diametral compression configuration, and their cracking load and load-bearing capacity were compared with both analytical and numerical simulations results, which indicated the better accuracy (between 10% and 16% of relative error) of the proposed analytical approach, proving the efficiency of the latter as a calculation tool for this innovative structural application of FRCM.
