Abstract:The effects of slag content and polymer-binder ratio on the properties of autoclaved and combined wet/dry-cured polymer-modified mortars using ground granulated blast-furnace slag (slag) and polymer dispersions such as a styrene-butadiene rubber (SBR) latex, and poly (ethylene-vinyl acetate) (EVA) and polyacrylic ester (PAE) emulsions are examined. As a result, the strength of the autoclaved polymer-modified mortars reaches a maximum at a slag content of 30% except for the autoclaved EVA- and PAE-modified mortars, and tends to increase or decrease with increasing polymer-binder ratio. The strength of the combined wet/dry-cured polymer-modified mortars reaches a maximum at a slag content of 40%, and is inclined to increase with increasing polymer-binder ratio. Irrespective of the curing conditions, their water absorption and chloride ion penetration depth tend to decrease with increasing slag content and polymer-binder ratio except for the autoclaved PAE-modified mortars. Their carbonation depth increases or decreases with increasing polymer-binder ratio.
