A practical method for production of foamed glass

Abstract EN

A two stage preparation method of foamed glass is described here aiming to achieve reproducibility and convenience.

Fritting of the solid components assembles the first stage ; where firing a mix of the frit, foaming agents and the liquid component gather the second stage.

Almost uniform cellular structure of the foamed glass is achieved at relatively low firing temperature of the mix (820°C for 10 min).

The cellular structure is enclosed with a shell of continuous surface.

Physical properties (density, porosity and water absorption) are measured for the product along with the mechanical properties that concerns production of building blocks, namely impact and compression strength.

The flexibility of the presented two stage preparation method simplifies future attempts to modify its properties to adapt particular applications.
