BINARY SILICATE GLASSES IN THE STUDY OF ALKALI-AGGREGATE REACTION

BINARY GLASSES OF THE OXIDES OF SODIUM, POTASSIUM, LITHIUM AND LEAD WITH SILICA WERE TESTED AS REACTIVE AGGREGATES WITH HIGH- AND LOW-ALKALI CEMENTS AND WITH HIGH-ALUMINA CEMENT AND PRESSURE-CALCINED GYPSUM PLASTER. IT WAS FOUND THAT THE SODIUM- AND POTASSIUM-SILICATE GLASSES ACTED AS REACTIVE AGGREGATES, WHILE THE LITHIUM- AND LEAD-SILICATE GLASSES DID NOT. THE EXPANSIVE REACTION OF THE SODIUM-SILICATE GLASS COULD BE INHIBITED BY SUBSTITUTING POZZOLAN (FINELY GROUND OPAL) FOR RELATIVELY LARGE PORTIONS OF THE CEMENT. /AUTHOR/
