Silica is found in several mineralogical phases, clayey and non-clayey, especially quartz its purest natural form and kaolinite Al 2 Si 2 O 5 OH 4. Figure 1 Index of plastic deformation by the humidity of the plasticity test by Pfefferkorn test. The Royal Society of Chemistry, 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.

Iron oxide is known to favor reddish tones in the burned parts and by the fluxing effect in the ceramics. Within this premise, the study aims to take advantage of a residue from the manufacture of ceramic coating. Where it was possible to decrease the water absorption and increase the mechanical strength.
Sample F displayed the best results as it was able to reduce the lead in the glass to a minimum in comparison to the other 5 samples. The higher the addition the more intense this effect. Effect on aesthetic quality and physical properties. 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.
Reducing the amount of pores favoring the reduction of water absorption and the increases of the mechanical resistance.
Bases para o futuro. Use of industrial ceramic sludge in brick production: How to cite this article. 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 that still generates improvements in the characterization of the final product and gains in sustainable marketing.
Effect of grog addition on the technological properties of ceramic.
Revista Escola de Minas, 68 3 The results expressed in Figure 1 indicate that samples containing approximately 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.
Samples A, B, D and F were put into the furnace with carbon graphite The duly identified formulations were packed in hermetically sealed plastic containers for moisture homogenization for a period longer than 24 h. Changing its characteristics in the finished product. With this waste it can possible of introducing faster firing cycles.
The NBR displays a list of known hazardous materials and their characteristics and can be related to the Code of Federal Regulations title 40, subtitle of the United States 40 C.

The civil construction sector, particularly in the manufacture of inputs, is constantly increasing with great potential impact. Such a productive increase demands a large amount of raw material which generates environmental problems related to the scarcity of natural resources.
The pressure inside the tube for samples E and F was set at 1. The monitors were manually dismantled using tools such as pliers, screwdriver, electric saw, saw, hammer, vise.
It is possible to observe that in the linear retraction of drying the results decrease abnr the increase of the added waste.
Ceramic materials are among those most traditionally used in the construction sector. According to Figure 3the loss of ignition of the standard mass and of the 10005 was coherent, since they presented values between 5.
A capacidade que este mineral apresenta para adsorver metais pesados tem despertado interesse de alguns autores. It is clear that recycling waste of CRT is important not only for mitigating environmental issues, but also for maximizing the value of the waste Zhang et al.
Cathode ray tube monitors were collected for these experiments; their manufacturing year varied from to The next step was intended to evaluate whether the lead removal had been able to convert the CRT from a hazardous waste to a non-hazardous waste according to the Brazilian regulation. This study ranks waste of CRT monitors according to Brazilian NBR ABNT, a norm and performs different detoxification methods to evaluate their efficiency in downgrading a hazardous waste to a non-hazardous waste.
Coal mine wastes recycling for coal recovery and eco—friendly bricks production. Is very important in generating income in the Brazilian industrial sector. Table 2 shows the chemical composition of the raw materials obtained by X-ray fluorescence spectrometry FRXwhere it is possible to verify the predominance of silica SiO 2 and alumina Al 2 O 3 in all samples. Thermochimica Actav. Geological assessment and utilization with drinking water treatment sludge in brick manufacture.
The mechanical strength 1005 a significant increase compared to the standard mass, as the residue content was increased the water absorption decreased and the resistance increased.
