Impact of metakaolin on mechanical performance of flax textile-reinforced cement-based compositesMajstorović, Filip (Avtor) Sebera, Václav (Avtor) Mrak, Maruša (Avtor) Dolenec, Sabina (Avtor) Wolf, Marco (Avtor) Marrot, Laetitia Sarah Jennifer (Avtor) textile-reinforced concrete (TRC)flax textilenatural fibresfinite elementmetakaolincement-based compositesopen accessThis study presents research on the effect of Portland cement (PC) replacement with metakaolin on the mechanical behavior of flax textile-reinforced cementitious matrices (TRCM). The composition of cementitious matrices and in-situ flax fibres was determined using X-ray diffraction and thermogravimetric analysis, while the reinforcement efficiency of the textile and mechanical behavior of TRCMs was investigated by three-point bending tests and finite element analysis. High amounts of PC replacement with metakaolin provided a calcium hydroxide-free environment, more suitable for the natural fibres, to avoid their degradation and embrittlement and, thus, significantly contribute to the ductility of the cement-based composite material.Elsevier Applied Science20222023-01-30 08:03:03Neznano16158UDK: 620.1/.2ISSN pri članku: 0958-9465DOI: 10.1016/j.cemconcomp.2021.104367COBISS_ID: 88927235sl© 2021 The Authors.
