Paper Title:
Investigation of Sulphate Attack on C-S-H Gel
  Abstract

C-S-H gel was prepared by extracting from the hardened cement paste, and was immersed in Na2SO4 solution and MgSO4 solution respectively. The microstructure of the C-S-H gel attacked by sulphate was observed by means of scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. It is found that C-S-H gel is attacked by both Na2SO4 and MgSO4, and gypsum forms whether in low or high concentration solution of Na2SO4 and MgSO4.
