Ten samples were pressed for each formulation in a total of 60 samples at a pressure of 5 tons. Adapted from ABNT b.
Polluting potential of Samarco Mineração S.A. solid waste: a Germano dam case study
At lower levels, iron oxide Fe 2 O 3 0. Chemical pollution of aquatic environment by priority pollutants and its control. Geological assessment and utilization with drinking water treatment sludge in brick manufacture. The higher the addition the more intense this effect. 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.

Figure 4 Water absorption versus mechanical resistance to diametric compression of the formulations carried out in the research.
Lead is also toxic for other animal 10050 and plants Menad, This dam is located in the county of Mariana and it is mainly used to retain the waste resulting from the iron ore treatment at the Germano Plant.
How to cite this article. The next step was intended to evaluate whether the lead removal had been able to convert 100055 CRT from a hazardous waste to a non-hazardous waste according to the Brazilian regulation.
The ideal moisture for making these specimens is determined by the Pfefferkorn plasticity assay.
A tube furnace structure was assembled to control the process Fig. The ceramic residue used in this work provided by a Brazilian company from Abt Catarina state from the process of washing and residues of enamels. Study for vitreous waste recovery in the formulation of heavy clay ceramics.
Characterisation of fired—clay bricks incorporating biosolids and the effect of heating rate on properties of bricks. Wastes that are not characterized in the NBR should be classified according to their leaching potential, which is evaluated using the NBR Edmond, OK Tel: The monitors were manually dismantled using tools such as pliers, screwdriver, electric saw, saw, hammer, vise. The monitors were weighed and their parts were separated and sorted into four categories: 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.
Due to the results obtained during the leaching test, the residue is toxic because it contains barium and lead in concentrations. The civil construction sector, particularly in the manufacture of inputs, is constantly increasing with great potential impact.
Cathode ray tube monitors were collected for these experiments; their manufacturing year varied from to The procedures presented the NBR simulate the leaching that may occur to a non-sheltered waste; a flowchart of the norm is presented in Fig. No part of this content may be reproduced or transmitted in any form or by any means as per the standard guidelines of fair use.
The use of ceramic sludge and recycled glass to obtain engobes for manufacturing ceramic tiles. The presence of calcium CaOmagnesium MgO and potassium K2O assist with increasing resistance to sudden changes in temperature.
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 abbt of view, can be used as a great flux that still generates improvements in the characterization of the final product and gains in sustainable marketing. After the burn, the samples were characterized by linear bant of burning, loss abnnt ignition, mechanical resistance to flexion diametric compression in a universal machine of mechanical tests EMIC model DL and water absorption.
A history of global metal pollution. Natural clay substitution by calamine processing wastes to manufacture fired bricks. Environmental profile of ceramic tiles and their potential for improvement. The other two components usually contain lead in their composition; the total amount of lead in a CRT may reach 3 kg Lecler et al. It can be observed that the waste presents significant levels of alkaline earth metals, mainly calcium oxide this also contributes to assist the sintering of the ceramic mass in certain temperatures.
Services on Demand Journal. Lead Removal and Evaluation The results 1000 the AAS obtained from the samples that had undergone the thermal process are displayed in Table 6. Despite having proper landfills for the disposal abtn CRT monitors, most of them end up in improper landfills or in no landfill at all Oliveira, BeforeCRT did not use high voltage in the electron gun, and thus, did not need as much lead in the glass for shielding Webster,
