| Abstract Scope |
The açaí tree is a palm tree found on a large scale in the northern region of Brazil, one of the main non-timber forest products and with great economic potential in Brazilian soils and other countries, such as Colombia and Peru. However, the wastes, which represent around 85% of the total fruit, cause a serious environmental problem, since around 365 tons of açaí seeds are discarded daily, with no reuse forecast. This research studies the feasibility of adding these wastes to mortars through the partial replacement of natural sand, at 10% in mass. Compositions with natural seeds, treated with NaOH and treated with KOH were used. After 28 days, the mortars were submitted to compressive strength, density and water absorption tests. It is concluded that the addition of the waste in all compositions generates a reduction in compressive strength, and its usefulness is limited to small repairs and fillings. |
