Verificação da viabilidade técnica da utilização de revestimento monocapa em edificações de blocos cerâmicos de alvenaria estrutural

Abstract

In the past few years, with the increasing number of civil constructions in Brazil, technological advances related to mortar coating increased in large expression. These coatings have been used in a large scale by companies of civil construction in order to minimize costs and thus increase the productivity and therefore reduce the waste of material. However, it becomes relevant the evaluation of the technical performance of this mortar called industrialized. Therefore, in this paper it is presented an evaluation of incorporated air content, traction in flexion, compression and adhesion in both types of mortars, considering the industrialized one (monolayer) and a conventional one (cement, lime and sand), in ceramic substrate of structural masonry. The main conclusions of this research were: the non-use of the roughcast layer on substrates generated a reduction of the adherence resistance to the traction and it was noted that the systems of mortared coatings obtained unsatisfactory performance when exposed to certain tests.
