Recycling of construction and demolition waste generated by building infrastructure for the production of glassy materials. The presence of silica SiO2 in main content is an indicator that the residue can improve the quality of the piece, mainly in the mechanical strength, since it is an oxide flux related to the verification of the material. Effect on aesthetic quality and physical properties.
This procedure was adopted in order to guarantee the same conditions established by the industrial process. Although the sector has a great environmental degrading potential due to mineral extraction by the high consumption of clay. Journal of Cleaner Production. Houston, we have a problem! The conformation was formulated using a laboratory press with a capacity of 15 tons. Click here to submit your manuscript The duly identified formulations were packed in hermetically sealed plastic containers for moisture homogenization for a period longer than 24 h.
Within this premise, the study aims to take advantage of a residue from the manufacture of ceramic coating. Utilizado geralmente para coletar amostras: 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. 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.
Ten samples were pressed for each formulation in a total of 60 samples at a pressure of 5 tons. Figure 3 Loss of ignition of the standard mass and formulations used in this research. Send the abnt nbr below via email or IM.
Such a productive increase demands a large amount of raw material which generates environmental problems related to the scarcity of natural resources. Mainly because it contains significant quantities of heavy metals lead and 1007 and considerable proportions of aluminum. Being a ratio of the initial measure to the final. According to Figure 3the loss of ignition of the standard mass and of the formulations was coherent, since they presented values between 5.
