Tijolos de adobe de solo-cimento com adição de resíduo de recapagem de pneus

Abstract

The civil construction waste is responsible for a large part of the damage to the environment, and is not, in most cases, disposed of properly or not having its potential for reuse. In order to minimize damages, means may be employed to reduce or reuse waste generated. In this context, the use of stabilized adobe with cement for civil construction is a practice that generates smaller impacts, presenting the possibility of its reuse several times, since it can be moistened and remolded, does not have to go through the burning process, is economically feasible , uses a much lower amount of cement than conventional construction processes, and uses the soil as a raw material, which is a renewable and abundant material. Tires are another type of waste, which is not necessarily the result of civil construction, but also causes a lot of damage to the environment and, most of the time, also does not have a correct disposal. Thus, this work proposed to add tire rubber in a soil-cement matrix, to make adobe bricks and analyze their physical properties and feasibility for application. For this, tests of resistance, durability, retraction and absorption were made. The blocks made with this type of addition did not show significant improvements in compressive strength and water absorption, but presented lower retraction and greater durability than the blocks of adobe without the addition of rubber fibers.
