Mechanical performance of cement mortar composites reinforced with nano and micro-scale cellulose fibers
The combination of the reinforcements at different levels can lead to a synergetic effect on the mechanical properties. In this work, the preparation and characterization of new cement mortars reinforced with conventional pulps at the micro-scale level and nanofibrillated cellulose fibres at the nano-scale level has been carried out. The conventional pulps have been obtained by subjecting sisal fibres to a soft mechanical treatment and the nanofibrillated cellulose have been prepared by the application of a high intensity refining process. Based on the preliminary results of this paper, it can be concluded that to obtain cement mortar composites with high modulus and resistance and high toughness the combination of both, cellulose nanofibers and microfibers could be interesting.
