Incorporação de resíduo de caulim em argamassa de alvenaria.

Abstract

In virtue the great amount of residues generated by the industries of kaolin improvement, governing and enviromentalists alert the population for the impact caused by these residues. For this reason, this work thesis will be dealing with it the incorporation of these residues in mortar traces for use in the civil construction, aiming to minimize the ambient impact, as also to produce mortar for the use in masony. In order to achieve the objectives of this thesis physical and mineralogy characterization was carried out, such as: grain sized distribution of sands, unitary specific mass, chemical analysis and diffraction X-rays. For the technological tests mixes for mortar of nesting and covering had been studied, with incorporation of 5%, 10%, 15% and 20% of kaolin residue, in substitution to the part of the whitewash sand also, mixes for mortar of nesting and covering with whitewash and sand and whitewash and kaolin residue. The results obtained showed that the mixes incorporated with up to 15% of kaolin residue were in agreement with specification (Brazilian specifications) ABNT, and allowed to be concluded that mixes it is feasible to use of the kaolin residue for the use in the civil construction with mortar of nesting and covering.
