摘要

With the objective of obtaining lime-pozzolana cements from the recycling of civil construction waste, four samples consisting of ceramic residue (bricks and tiles), artificial pozzolana and two samples of hydrated lime were studied. All samples were characterized by chemical analysis, thermal differential analysis, X-ray diffraction, specific area and activity pozzolanic. The waste samples and ceramic residues were ground in a ball mill for 90 min and that of artificial pozzolana in a disk mill. The alternative mortars were prepared using as aglomerate lime pozzolanic cement in proportion of 30-70, 40-60 and 50-50% of lime and pozzolana, respectively. The specimens were cured for periods of 7, 28 and 60 days and submitted to the RCS trials. The results obtained show that the recycling of civil construction waste is a promising technique which may generate low cost elements, destined for civil works and its use implies in the preservation of the environment and in the improvement of the quality of life of the population in general.
