20.500.12556/DiRROS-16158 Impact of metakaolin on mechanical performance of flax textile-reinforced cement-based composites This 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. textile-reinforced concrete (TRC) flax textile natural fibres finite element metakaolin cement-based composites open access tekstilni beton lan končni elementi metakaolin cementni kompoziti odprti dostop true false true Elsevier Applied Science Angleški jezik Slovenski jezik © 2021 The Authors.
