POLLUTION-FREE SILICATE BINDERS TO PRODUCE CONSTRUCTION MATERIALS

The processes of silicate binding material production with the use of mechanochemical methods have been developed. A silicate binding material is sodium liquid glass with a hardener – pollution-free mineral natural additives. Low-temperature non-autoclave methods of sodium liquid glass production with the use of a wide range of silicate-containing materials have been developed.

MECHANOCHEMICAL SYNTHESIS OF BINDING MATERIAL FROM SAND

ADVANTAGES:

• tearing strength of binder – 50 MPa
• crushing strength of products – more than 200 MPa
• water-insoluble after firing at 150 0C
• don’t swell up at heating

APPLICATION OF SILICATE BINDER FOR THE PRODUCTION OF CONSTRUCTION MATERIALS

Fire-resistant, pollution-free water-resistant wood particle board from sawdust, chip, bark, rice husk etc.

Advantages:

• changing of phenol-formaldehyde resin;
• usage of waste of wood-working industry and agriculture

Expanded clay from industrial and domestic waste

Advantages:

• changing from mineral wool to a cheaper and more durable material;
• usage of production waste

Decorative building plates (“artificial granite”) produced with the use of silicate binder

Advantages:

• increased hardness;
• great fire-resistance;
• absence of dangerous organic binders

Pilot tests have been carried out.
RF patents have been taken out.
