Resumen
During its operations, the oil industry generates a lot of waste, including gravel from
drilling. Control of environmental impacts caused by this waste represents a major
challenge. Such impacts can be minimized when it is given an appropriate
management by being properly treated and properly disposed or recycled. The
properties of these materials can be greatly influenced when a waste is added to its
composition. This work aims to study the incorporation of gravel waste oil-well drilling
in the standard body for production of red ceramic from a ceramic industry in São
Gonçalo do Amarante / RN. The success of the incorporation can minimize costs in
the production of ceramic pieces and reduce the environmental impacts caused by
waste. The raw materials used were collected, characterized, and formulated with the
percentages of 0%, 20% and 40% by weight of substitution of residue were
synthesized at temperatures of 900, 1.010 and 1.120 °C using 30 minute firing
intervals, 1 hour and 30min and 2 hours and 30 minutes, based on a factorial design
2³. Samples were then subjected to the tests of Water Absorption, Linear Retraction
Firing, Flexural Rupture Strength, Apparent Porosity and Apparent Specific mass and
Scanning Electron Microscopy (SEM) of break section. The results showed that the
use of the residue for the manufacture of the ceramic products is possible (tiles,
bricks and massive hollow bricks) replacing the clay to 40%, meeting the
requirements of the standard and the literature for the technological properties of the
final product.
