Effect of grog addition on the technological properties of ceramic. Such a tool considers industrial wastes as by-products or alternative materials that can feed another industry.
Again, these results are related to the considerable content of fluxes in the waste. The presence of Fe 2 Abbnt 3 is associated to steel grit; and CaO, which can act as fluxing 19associated to abnt nbrboth used in the mud. Figure 1 Index of plastic deformation by the humidity of the plasticity test by Pfefferkorn test. The graph of Figure 2 shows the results of total linear thermal retraction drying and firing of the formulations and standard mass STD used in the study.
More presentations by Renato Verardino Untitled Prezi. The analyzed waste is considered as class I—Dangerous due to the presence of toxic elements in the leachate above the Brazilian waste classification standard.
Mainly because it contains significant quantities of heavy metals lead and cadmium and considerable proportions of ant. Over time, the planet’s natural resources, formerly considered abundant, have been used indiscriminately generating significant amounts of solid waste. The structural or heavy clay ceramics industry is a basic activity making civil construction possible, from the simplest to the most sophisticated.

This work also contributes to the reduction of the environmental impact and favors the sustainable development of the heavy clay ceramics contributing to the improvement of the quality of the pieces.
Materials and methods The ceramic residue used in this work provided by a Brazilian company from Santa Catarina state from the process of washing and residues of enamels. The clay mass was obtained from the mixture of four clays that was collected after complete homogenization and removal after the rolling process.
