Abstract  

Waste compromises environmental preservation as well human health in many countries. Recycling is an alternative that sometimes represents the only economical activity for a significant population in the big cities. Almost 3% of waste materials in Brazil are vitreous. Ceramic production adding waste glass is possible with advantages of costs reduction associated to decrease on firing temperatures and to the raw material itself. At present paper up to 80 mass% of waste glass was added to clay. The sintering temperature decreased linearly and the shrinkage increased with glass content, an effect more pronounced for high glass amount.

Abstract  

The problems of determination of zinc in clay, ceramics and soils via 65Zn using INAA are discussed. The applicability of different approaches for solving the influence of 46Sc and 152Eu by gamma-spectrometry on the line of 65Zn at 1115.5 keV are experimentally evaluated. The application of the correction program ANGES for the calculation of the net peak area is demonstrated. All discussed approaches are checked by analyses of 10 SRM"s: Ohio Red Clay, Lefkandi brick, IAEA-SRM-Soil-1, IAEA-SRM-Soil-5, IAEA-SRM-Soil-7, IAEA-SRM-SL-3, GBW-08303, GBW-07406, NIST-SRM-2709 and BCR-SRM-520.
