AbstractThe dimensional stability of C-S-H (with varying C/S ratios) in saturated-lime water, distilled water and a methylene (MB) solution was investigated in this study. Two distinct regions of C/S ratio exhibited maxima in length change versus C/S ratio curves generated from results in all three test solutions. Differences in behavior in all three solutions were minimal. It would appear that the C-S-H nanostructures that quickly form in MB solution are comparatively stable in aqueous media. Possible mechanisms for the length change behavior are discussed.
