Abstract
Inventia se refera la procedeul de obtinere a unui agregat usor artificial cu greutate forte redusa 120-300 kg/m cub cu dimensiunea granulelor 3-40 mm necesar pentru obtinerea unor betoane de izolatie si betoane de izolatie si de rezistenta. Expandarea la temperatura 800-950 degree C a unui amstec gramulat în prealabil din perlit, deseu de perlit, perlite greu expandabile sau alte tufuri vulcanice macinate fin sub 100 niu m în amestec cu praf de carbune, o solutie alcalina, o solutie de azotat alcalin granulele fiind pudrate cu cenusa de termoventrala si uscate.
