| Abstract Scope |
The use of agro-industrial residues in the production of geopolymeric mortars has been a point of growing scientific interest both for gains in mechanical properties, but also for sustainability. In this context, natural fibers stand out, as they are biodegradable, have lower energy consumption, availability, low density and low cost when compared to synthetic fibers. The natural fiber from açaí is an example of agro-industrial waste generated in large quantities, and its disposal is a major environmental problem. Thus, the objective of this work was to produce a metakaolin geopolymeric mortar with the addition of açaí fibers at 1 and 2% in relation to the mass of the precursor, with fibers not treated and treated with 5 and 10% of NaOH. Then, the samples were investigated in the hardened state with resistance to flexion and compression tests and in the fresh state by the Vicat and dropping-ball tests. |
