Introduction

The presented invention relates to a heat-insulating glass-ceramic non-pelletized material having macroporous structures, which is produced from bottom ash obtained from treatment plants of municipal solid waste. It is an ecological substance of homogeneous type, having reproducible properties in all points, that provides approximately twice the compressive strength relative to comparable solutions which are currently available on the market.

Technical features

The proposed invention relates to a heat-insulating glass-ceramic not-pelletized material having macroporous structures, which is produced from bottom ash obtained from treatment plants of municipal solid waste, that is appropriately mixed with soda-lime glass in addition to a binding agent, preferably kaolin. Such compounds are then placed in the melt mixture grinded in granular form and subsequently transferred into a mould having a predetermined shape. It is a homogeneous ecological substance that does not have the addition of foaming agents and offers about twice the mechanical compressive strength compared to the generally used solutions. In addition, the material has been found to be extremely safe in case of fire because it is totally fireproof, so it does not liquefy and does not generate toxic fumes and gases.

Possible Applications

  • Thermal insulation for civil and industrial buildings.

Advantages

  • The material is realized with recicled glass and non-hazardous special waste;
  • Thermal insulation;
  • Waterproof;
  • Fireproff;
  • It does not generate toxic fumes and gasses.
