Durability of sintered materials modified by alternative silicate filling agents

Abstract

The issues contained in the study are focused mainly on the durability of glassbased sintered materials for whose production alternative silicate filling agents were used. These sources are waste glass gravel from collected coloured container glass, disassembled TV screens and, last but not least, so-called secondary energy products, i.e. mainly fluid fly-ash and blast-furnace slag. It is generally known that currently fluid fly-ash is not being used as a secondary raw material much. The same applies to the above-mentioned raw glass. I focused mainly on the frost impact on the strength features of sintered materials using both crystalline and amorphous silicate filling agents. I drew up 19 formulas in total. Two sets of test samples consisting of five specimens were made for each formula. The abovementioned analyses of the samples were carried out and subsequently assessed. I found out that amorphous filling agents had a positive effect on the durability features of the produced materials, whereas secondary products had a negative effect. Therefore, crystalline substances do not seem to be suitable for production of glass-silicates considering their strength features in terms of durability which is stated in this study.
