Services on Demand Journal. The higher the addition the more intense this effect. August 07, Published: The study was to analyze the technical feasibility of the incorporation of vitreous waste, from enamel decanters, into a heavy clay mass for fired clay ceramic structural block production.
The next step in this study was the removal of lead from the CRT by thermal processes. The pressure inside the tube for samples E and F was set at 1. Adapted from ABNT b. The results of mechanical strength obtained by the diametrical compression method and the water absorption presented in the graph Figure 4.
Recycling of construction and demolition waste generated by building infrastructure for the production of glassy materials.
The possible abtn reactions are as follows Veit et al. 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.

Thermochimica Actav. The big variance among the samples is probably related to the year the monitors were manufactured.
Effect of grog addition on the technological properties agnt ceramic. Bases para o futuro. Figure 3 Loss of ignition of the standard mass and formulations used in this research. These devices became obsolete because of emerging technologies such as LCD, LED and plasma; thus generating a huge stockpile of e-waste worldwide. The obtained results encouraged a study regarding the hazard potential of CRT monitors.
These tailings have the potential to be used as an alternative raw material in the manufacture of heavy clay ceramics and therefore, from a manufacturing point of view, can be used as a great flux abng still generates improvements in the characterization of the final product and gains in sustainable marketing.
Iron oxide is known to favor reddish tones in the burned parts and by the fluxing effect in the ceramics. At lower levels, iron oxide Fe 2 O 3 0.
MedCrave Group is ardent to provide article reprints at an instant affordable Read more In order to make sure the monitor samples used in this work had similar lead distribution to the ones from previous studies Table 1the three milled glass parts were analyzed by X-ray fluorescence XRF using an Axios Advanced PANalytical, Almelo, Netherlands. Use of industrial ceramic sludge in xbnt production: Currently produced ceramic coatings are generally composed of three distinct layers: The ceramic mass supplied by a ceramic company from South of Santa Catarina, Brazil used for the manufacture of structural blocks.
Wastes that are not characterized in the NBR should be classified according to their leaching potential, which is evaluated using the NBR The other two components usually 10005 lead in their composition; the total amount of lead in a CRT may reach 3 kg Lecler et al. Characteristics of fired bricks with co—combustion fly ashes.
Cathode ray tube monitors were collected for these experiments; their manufacturing year varied from to Figure 1 Index of plastic deformation by the humidity of the plasticity test by Pfefferkorn test.
BeforeCRT did not use high voltage in the electron gun, and thus, did not need as much lead in the glass for shielding Webster, In order to open the vacuum sealed tubes, the monitors were placed behind a wooden shield and the metallic threads were removed using a set of pliers. The results from the AAS obtained from the samples that had undergone the thermal process are displayed in Table 6.
Study for vitreous waste recovery in the formulation of heavy clay ceramics
However, given that the sample was glass, the XRF equipment assumes the atoms are in their most oxidized state – resulting in the chemical compounds shown in Table 4. The amount of sample prepared was 1 kg for each formulation and then homogenized manually with the help of a metal spatula and then an eccentric mixer. To ensure personal safety of the operators, the following personal protective equipment PPE were worn: Geochimica et Cosmochimica Actav.
Revista Escola de Minas, 68 3 Pollution causes, effects and control.
This factor causes the number of researches to increase the incorporation of a series of residues in ceramic mass, such as glass, 1415 ashes of the most diverse sources, 16 mining wastes, 19 sludge from a wide variety of treatment sources, 20 waste from heavy abht ceramic process 23 and other wastes.
