PORTELLA, K. F.; JOUKOSKI, A.; FRANCK, R. and DERKSEN, R.. Secondary recycling of electrical insulator porcelain waste in Portland concrete structures: determination of the performance under accelerated aging. Cerâmica [online]. 2006, vol.52, n.323, pp.155-167. ISSN 1678-4553. http://dx.doi.org/10.1590/S0366-69132006000300008.
The use of rubbish and other kinds of domestic and industrial wastes on civil construction has been a common practice in many developed countries, due either to the increase in the amount of waste and the resultant reduction of appropriate places to its final disposal, as well as to the severity and steadiness of environmental inspection organizations. In order to provide beforehand manners to solve or reduce these problems, study of recycling and co-disposal of waste from porcelain electrical insulators in concrete was proposed. Besides the occurrence of expansive reactions, which may be harmful to the stability of important structures, the overall results were encouraging. Some contaminants found in the three phases of porcelain contributed to the happening of alkali-aggregate reaction, which can easily inhibited by the using of special cements, such as a sulfur-resistant one.
