Aproveitamento de Caco para a produção de material vítreo

Abstract

Glass is one of the most used materials by Man, in many areas, such as civil construction, packaging sector, electronics industry, etc. Although its widest application, generates a lot of solid waste, bringing serious consequences to the environment. The versatility of the use of glass is mainly due to its chemical, thermal, transparency, among other characteristics. However, the glass's high strength makes it non-biodegradable, accumulated over many years in the environment. Glass is a 100% material recyclable, minimizing the use of raw material and avoiding its disposal when environment. The present work consisted in the production of ceramic frits from vitreous waste, namely, brown glass bottles, glass bottles green and construction glass. Attack evaluation tests were also carried out. chemical to the produced frits, having been noticed greater resistance in acidic solutions (HCL) and lower in basic solutions (NaOH). In addition to the chemical attack, it was also determined the density of both the glass shards and the frits ceramics produced, with no significant change, but a increasing tendency of the density of ceramic frits in relation to glass shards.
