ABSTRACT = {The use of natural lignocellulosic fibers (NLFs) as a reinforcement mechanism for cementitious composites, such
as mortar, has been investigated in the last decades. However, their application has often been restricted to technological evaluation research. A NLF with great potential the curaua, which after treatment with NaOH solution,
proved to be technologically feasible for mortars reinforcement based on cement and lime. The objective of this
research was the comparative evaluation between a traditional mortar, based on cement and lime, with
1:1:6:0.8 ratio of cement: lime: sand: water, and a modified mortar with addition of 2 wt.% treated curaua fiber
in cement mass by evaluating environmental and durability aspects. After a curing time for 28 days, environmental assessments were carried out and durability methodologies were evaluated. The tests performed were: (i) attack
by chlorides and sulfate, (ii) the wetting and drying cycles, and (iii) slake durability test. The results showed that
the mortar with the addition of curaua fiber presented a similar behavior to the reference mixture, both in terms
of environmental and durability aspects. This modified mortar is able to be used in internal and external environments, the latter with some conditions. Besides, it also contributes to the promotion of sustainable use of curaua fiber.},
