Abstrakty

PL

Zbadano przydatność fosfogipsu, odpadu z produkcji kwasu fosforowego (surowcem był apatyt z półwyspu Kola w Rosji). W tym celu fosfogips, po neutralizacji wapnem, z dodatkiem 5% gliny i 5% mielonego szkła, prażono w temperaturze 900°C. Ta metoda daje cement anhydrytowy o dobrych właściwościach, którego wytrzymałość po 28 dniach twardnienia wnosi 55 MPa, w przypadku próbek suchych.

EN

The possibility of phosphogypsum, byproduct from the production of phosphoric acid (raw material - apatite from Kola peninsula, Russia), application for anhydrite cement production. Phosphogypsum, neutralized with lime, with addition of 5% of clay and 5% of ground glass was burned at 900°C. This method was assuring the production of anhydrite cement of high quality with compressive strength of 55 MPa of dry samples.
