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.
