Abstract
<jats:p>Glass-ceramics composites were produced based on fly-ash obtained from coal power stations, metallurgical slag from ferronickel industry and waste glass from TV monitors, windows and flasks. Using 50% waste flask glass in combination with fly ash and 20% waste glass from TV screens in combination with slag, E-modulus and bending strength values of the designed systems are increased (system based on fly ash: E-modulus from 6 to 29 GPa, and bending strength from 9 to 75 MPa). The polyurethane foam was used as a pore creator which gave the material porosity of 70(5% (fly ash-glass composite) and a porosity of 65( 5% (slag-glass composite). E-modulus values ...
