Elaboration and characterization of an insulation Material based waste glass

Abstract

he policy of energy conservation and constructionof acoustic comfort is the

basis of search for new compounds to improve the performance of materials currently

on the market.

It is within this context that our work to obtain abuilding material much lighter with

properties improved thermal and acoustic insulationfrom waste glass and calcium

carbonate as a foaming agent.

The manufacture of foam glass from waste glass recycling is a way that fits with the

objective of environmental protection and maximum recycling of household waste. The

energy savings achieved through the use of cullet result in a decrease in air pollution,

especially carbon dioxide (CO

2), and reduced the price of glass.

The results of the microstructure clearly demonstrate that the addition of CaCO3

increases the porosity of the foam glass which gives a low thermal conductivity and

increases its thermal insulation capacity (λ= 0.026 W/Nm

2

), which promotes its use in

the building industry.
