Incorporação de Resíduo de Cinza da Queima de Madeira na Produção de Tijolos Cerâmicos Ornamentais

The increasing production of waste in the most diverse industries has generated studies
with the purpose of destiny them correctly. In this destination, the residue can be
incorporated in the production cycle of the same industry where it was generated or in
other types. In addition to the "reject" type to be incorporated, different concentrations
are studied, aiming at maximum incorporation without affecting specific properties. The
construction industry, because of its versatility, provides the possibility of insertion of the
most diverse types of materials in its production, standing out as an area of many
opportunities for recycling. This work studied two of these possibilities: the use of
recycled aggregates in the production of concrete and the incorporation of gray residue
from the burning of the wood of the ceramic industry in the production of ornamental
bricks. In both situations, it is concluded that it is possible to substitute the natural material
for recycling, provided that the concentrations previously studied are respected, in order
to guarantee quality in the final product.
