Length change of C–S–H of variable composition immersed in aqueous solutions

The dimensional stability of calcum silicate hydrate phases (C–S–H), (with varying C/S ratios) in saturated-lime water, distilled water and a methylene 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 behaviour in all three solutions were minimal. It would appear that the C–S–H nanostructures …
