| Abstract Scope |
The açaizeiro is a palm tree found on a large scale in the northern region of Brazil, one of the main non-timber forest products with great economic potential. However, residues, which represent about 85% of the total fruit, cause a serious environmental problem, since about 365 tons of açaí seeds are discarded daily, with no provision for reuse. This research studies the feasibility of adding these residues to the coating mortars through the partial replacement of sand, in 10% of the mass. Six compositions were used, one being a reference (trace 1:3) and the others with the presence of the residue. The mortars were subjected to several tests in the plastic and hardened state. It is concluded that the addition of the seed in all compositions generates a reduction in mechanical strength, on the other hand improves several properties in the fresh state, which is positive for the proposed application |
