Abstract

Effects of K2SO4 and Na2SO4 on C3S formation and its microstructure were investigated. C3S formation was not influenced by addition up to 6.0wt% of K2SO4 as SO3 base, however it was prevented by only 1.0wt% of Na2SO4 addition. C3S prevention by added Na2SO4 was the reason why C2S stabilized by Na+ and SO42- could not react to C3S. Added K2SO4 appeared as K2SO4, however added Na2SO4 appeared as the form of Na2xCa3-xAl2O6, (Na0.8Ca0.1)SO4 and Na2SO4 in interstitial phase.
