After the burn, the samples were characterized by linear retraction of burning, loss of ignition, mechanical resistance to flexion diametric compression in a universal machine of mechanical tests EMIC model DL and water absorption. More specifically the enamel industry as a raw material to incorporated with the manufacture of ceramic blocks for masonry. 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.
Production of bricks from waste materials—A review Constr. Characteristics of fired clay bricks with waste marble powder addition as building materials. The results of mechanical strength obtained by the diametrical compression method and the water absorption presented in the graph Figure 4. 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.

Ukwatta A, Mohajerani A. Alumina is also generally associated with kaolinite, being a very characteristic mineralogical phase of clays . Characterisation of fired—clay bricks incorporating biosolids and the effect of heating rate on properties of bricks. Is very important in generating income in the Brazilian industrial sector. 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.
Therefore, abnt nbr waste is not a plastic material, which abn contribute to achieving ideal plasticity of the mixture in the extruder. Iron oxide is known to favor reddish tones in the burned parts and by the fluxing effect in the ceramics.

August 24, Correspondence: The use of ceramic sludge and recycled glass to obtain engobes for manufacturing ceramic tiles.
The economy already gives indications that will grow again which will improve the construction market. It is possible to observe that in the linear retraction of drying the results decrease with the increase of the added waste. Waste reuse abnr a way to make the dimension stone industry more environmentally sustainable, minimizing 1007 in landfills, or avoiding improper disposal, which can cause abtn, air and water contamination.
Characteristics of fired bricks with co—combustion fly ashes. Therefore, it is possible to analyze the difference in the linear retraction of burning of the formulations. Ceramic materials are among those most traditionally used in the construction sector.

To determine the ideal extrusion humidity of the formulated samples, the plasticity test is performed with the Standard Mass STDwith the following humidity percentages: In a mixture with water in a ratio of 1: 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.
This procedure was adopted in order to guarantee the same conditions established by the industrial process. The presence of calcium CaOmagnesium MgO and potassium K2O assist 100007 increasing resistance to sudden changes in temperature. Ten samples were pressed for each formulation in a total of 60 samples at a pressure of 5 tons.

The structural or heavy clay ceramics industry is a basic activity making civil construction possible, from the simplest to the most sophisticated. The samples are press with diameters of 73 mm and thickness of 15 mm identified, weighed, and measured.
Over time, the planet’s natural resources, formerly considered abundant, have been used indiscriminately generating significant amounts of solid waste. Tantawy MA, Sa R. Coal mine wastes recycling for coal recovery and eco—friendly bricks production. Houston, we have a problem! 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 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.
