PRODUCTION OF POROUS GLASS-CRYSTALLINE MATERIALS BASED ON GLASS CULLET AND CONVERTER SLAG

The study conducted the research aimed to obtaining a porous glass-crystalline materials based on glass cullet and converter slag, which was used as gas-forming additive. In this work, chemical phase compositions of studied slag were analyzed, differential thermal analysis its sample carried out. Converter added composition masses in an amount 2.5 30 wt%, rest cullet. Вurning samples out temperature range 850-925 ° C. For under study, using sand volumetric meter, volume determined swelling coefficient calculated, compressive strength determined, type structure, depends average diameter prevailing pores, analyzed. dependence investigated burdening burning has been established. To obtain with 2.16-2.67 uniform fine-porous structure (predominant pore size less than 0.5 mm), it is optimal introduce into 10-15 recommended their 850-900 Analysis obtained indicates presence wollastonite main crystalline phase, which, due acicular crystals, reinforcing effect contributes increase characteristics. developed can be insulation aggregates lightweight concrete.
