Effect of recycled geopolymer concrete aggregate on strength development and consistence of Portland cement concretes

摘要

1 Leaching of SO_4~(2-), Na~+ from Recycled Geopolymer Concrete Aggregate 2 Initial setting of cement paste affected by Recycled Aggregate leachate 3 Distinct action of Ca~(2+), K~+ and Na~+ ions 1 Strength development mechanism of concrete is affected by Recycled Geopolymer Concrete Aggregate incorporation 2 Strong correlation of source concretes' chemical composition to their effect on recycled aggregate concrete strength and consistence 3 Investigation of aggregate-matrix interaction required.
