| Abstract Scope |
The use of natural lignocellulosic fibers (NLF) favors a series of technological properties when used in cementitious composites. Brazil, due to its climatic and geographical characteristics, has an abundant variety of natural fibers that can be used for this purpose. The objective of this work was to evaluate the characteristics of different mortars in the hardened state reinforced with the addition of açaí fiber, subjected to different methodologies of surface treatment, such as immersion in a solution of sodium, potassium and calcium hydroxides at a concentration of 10% of hydroxide. in relation to the mass of water. Mortars with a dosage of 1:3 (cement: sand) were made to reinforce structures with additions of 0% (reference), 1.5%, 3.0% and 4.5% of the açaí fiber, in relation to the mass. of cement. The results were analyzed by statistical tests and demonstrated that the treatments with potassium hydroxide (KOH) showed the best results. |
