Con formato: Inglés (americano). Research regarding the use of alternative materials as a substitute to ordinary households, mainly in concrete and mortar, is recent and recurring practice in recent decades in Brazil. The ceramic waste because of their similarities, physics and chemistry, with ordinary aggregates coupled with control of particle size are suitable for use in concrete. It is estimated that the annual Brazilian passive electrical porcelain insulators is 25,000 tons, which are often discarded degrading the environment. The method of use of this and subsequent grinding replacing porcelain aggregates, fine and coarse in concrete were investigated by replacing the combined content of 25 %, 50 %, 75 % and 100 of both clusters. The results of mechanical tests combined with microscopic analysis of ITZ folder by Scanning Electron Microscopy (SEM) was shown to be possible to use this to replace the common ceramic aggregates giving the concrete when they used higher resistance and consequent mechanical durability, contributing, even in small ways to decrease the extraction of aggregates common in nature and being a possible and viable option for ceramic industries producing electrical porcelain insulators.

Keywords : porcelain insulator; concrete; alternative materials; porcelain aggregates.
