abstract = {Babassu carbohydrate fibers (BCF) are abundant and renewable materials
that are currently underutilized. The present work evaluates the use of alkaline-
treated BCF (TF − 0.6, 1.0, 1.4% w/w) as additive to cementitious mortars.
Mass consistency, specific mass, water absorption, void ratio, and porosity, as
well as compressive and indirect tension fracture strengths, were evaluated
and compared to control mortars (without fiber addition). The results confirmed
that the treated BCF can be an effective alternative as a potential
reinforcement in cementitious composites. Furthermore, they are prepared
by an alkaline treatment that is easy to operate, cost-effective, and efficient.
The addition of BCF to the cement matrix decreased the water absorption
capacity and void ratio, whereas increased compressive and tensile strength
compared to mortars prepared in the absence of BCF. In particular, the
addition of 1.0% of TF increased the compressive strength by up to 77%.
Good interfacial adhesion of the alkaline-treated BCF with the rest of mortar
components resulted in an increase in the values of mechanical properties.
The studied fibers are potential materials for new sustainable mortars with
improved properties.},
