Four different types of cellulose fiber materials were used: cellulose UFC100, cellulose B400, nanofibrillated cellulose, and Lyocell fiber. For all investigated composites the total amount of admixed cellulose was between 1 and 2 wt%, the amount of admixed sodium alginate was 0.5 wt%. We determined the morphology of the composites and observed that the particle and fiber dimensions of the admixed cellulose affect the mode of gypsum–gypsum interlocking and the total porosity of the composites. This in turn had a substantial influence on the mechanical properties of the final composite materials. The addition of sodium alginate resulted in an increase of ultimate strain values. Composites with Lyocell fiber, a synthetic fiber, also had a high Young’s modulus. eng Characterization and mechanical properties investigation of the cellulose/gypsum composite journal article URL https://docta.ucm.es/bitstreams/52a7a438-68f1-404b-89b3-e47a7709252b/download File MD5 f3c70625c27edff1f4ed2c4e339685e0 1911873 application/pdf Characterization and mechanical.pdf
