Resistência Mecânica De Tijolos Adobe Reforçados Com Resíduo De Casca De Ovo

Abstract

The civil construction sector directly impacts the development of a nation. On the other hand, it consumes a large amount of energy, natural resources and the sector with the highest waste disposal. The concern with the environmental impact caused by the development of this field has been the subject of several researches. Most of the studies converge on the recycling of waste generated and the reinsertion of these materials in the construction cycle. In this work we investigated the loss of moisture and the resistance to mechanical compression of adobes produced with recyclable mortar, crushed eggshell residues and hydrated with different dosages of vinasse and water. The materials were processed manually, pressed in a hydraulic press and cured for 7 and 14days. The study of the granulometry of the crushed raw material was carried out. During the curing process, moisture loss was studied. The specimens were tested by measures of resistance to mechanical compression. The results of moisture loss and mechanical tests showed, for one of theproposed features, values close to the standards required by the Brazilian Association of Technical Standards, indicating that these residues can be a promising alternative for the manufacture of bricks and contribute to reducing the impact environmental and water resource savings.
