Resumo: | This dissertation presents a hybrid ceramic block the use of which reside in the
buildings executed with walls. Initially, we conducted a survey on the requirements
and / or norms prevailing in Brazil about structural ceramic blocks, making use of the
experiences in other countries. This work seeks new materials and / or products in
order to maintain or increase the compressive strength of the ceramic blocks, without
neglecting the other properties. Then was collected materials (clay and crushed
powder) and an approach on the characterization, through fluorescence, Mineralogy,
vitrification curve and characterization of these materials used in the manufacture of
the blocks by Ray Diffraction "X" and SEM. Subsequently it was made, numbered
and measured dimensions of about 150 bodies of the test piece (hybrid ceramic
blocks in small sizes) with varying percentages of 0%, 5%, 10% and 15% substitution
of crushed clay powder. After sintering of the bodies of the test piece at temperatures
of 900oC, 1000oC 1100oC and with a heating rate of 5oC/minuto and level of 1 hour,
the samples were submitted to the tests (compressive strength and water absorption)
and calculated their retractions, which were subsequently carried out the analysis of
the results according to the criteria and parameters required by Brazilian legislation
and standards in force |
