EFFECTS OF GROUND GRANULATED BLAST FURNACE SLAG AND HIGH-PURITY SILICA ON PROPERTIES OF AUTOCLAVED POLYMER-MODIFIED MORTARS

摘要

The effects of slag and silica contents andpolymer-binder ratio on the properties of autoclaved polymer-modified mortars using ground granulated blast furnace slag(slag) and high-purity silica (silica) are examined. As a result, inthe autoclaved polymer-modified mortars using slag and silica,EVA- and PAE-modified mortars appear to be degraded by thesaponification of EVA and PAE polymers, but SBR-modifiedmortars do not give such degradation with the use of slag andsilica. SBR-modified mortars using slag and silica provide highstrength, fair waterproofness, good chloride ion penetrationresistance and carbonation resistance.
