Abstract Scope |
The natural fiber from açaí (Euterpe oleracea Mart.) is an example of agroindustrial waste generated in large quantities in Brazil. The objective of this work is to evaluate the technological characteristics of mortars in their fresh state, reinforced with the addition of natural açaí fiber, submitted to a type of surface treatment, such as immersion in NaOH, KOH and Ca(OH)2 in the concentration of 10%. The mixtures have a ratio of 1:3 (cement: sand) with additions of 0 (reference), 2.5%, 5.0% and 10% of the açaí fiber, in relation to the cement mass. Tests were carried out to determine the consistency index, mass density in the fresh state, incorporated air content, water retention. The results showed that the 4.5% mixture treated with KOH was the one that showed the best results due to its lower density and one of the highest water retentions. |
