The results of mechanical strength obtained by the diametrical compression method and the water absorption presented in the graph Figure 4. Nnr use of ceramic sludge and recycled glass to obtain engobes for manufacturing ceramic tiles.
It is possible to observe that in the linear retraction of drying the results decrease with the increase of the added waste. Neither you, nor the coeditors you shared it with will be able to recover it again. Delete comment or cancel. The results also indicate a reduction in loss of ignition as the residual content increases, since the residue presents a lower amount of organic matter 4.
Our aim is to study the technical feasibility nr dimension stone waste addition to bnr clayey mass used in roof tile production. After firing, the following characteristics were evaluated: Send this link to let others join your presentation: The graph nr Figure 2 shows the results of total linear thermal retraction drying and firing of the formulations and standard mass STD used in the study.
The structural or heavy clay ceramics industry is a basic activity making civil construction possible, from the simplest to the most sophisticated. Please log in to add your comment. Delete comment or cancel.

This abnt nbr needs to be solved by approaching academic research bbr the productive sector. The clay mass was obtained from the mixture of four clays that was collected after complete homogenization and removal after the rolling process. Chemical and mineralogical characterization tests of the raw materials carried out.
Ten samples were pressed for each formulation in a total of 60 samples at a pressure of 5 tons.
The waste it is 100007 ceramic sludge, rich in vitreous and fluxing materials that if deposited in inappropriate places cause contamination of the environment. Currently produced ceramic coatings are generally composed of three distinct layers: Journal of Cleaner Production. The conformation was formulated using a laboratory press with a capacity of 15 tons. Reset share links Resets both viewing and editing links coeditors shown below are not affected.

Natural clay substitution by calamine processing wastes to manufacture fired bricks. Copy code to clipboard. Through the work carried out, it can be said that the addition of the enamel waste to the clayey mass of heavy clay ceramics influences its properties.
Please log in to add your comment. Due to the results obtained during the leaching test, the residue is toxic because it contains barium and lead in concentrations. Therefore, innovative approaches to the production of heavy clay ceramics that are less dependent on virgin sources are highly encouraged from the perspective of protecting natural resources and sustainable development.

The mechanical strength had a significant increase compared to the standard mass, as the residue content was increased the water absorption decreased and the resistance increased. The higher the addition the more intense this effect. Mainly because it contains significant quantities of heavy metals lead and cadmium and considerable proportions of aluminum. Is very important in generating income in the Brazilian industrial sector. Atterberg limits on the raw materials are presented in Table 2.
