Paper Title:
Effect of Mixed Material on Sulphoaluminate Cement Sulfate Attack Resistance
  Abstract

In order to enhance the ability of sulfate resistance of the coastal engineering, the effects of hydroxyapatite, shell and calcium carbonate on the mechanical performance and sulfate attack resistance were studied. The composition and structure of hardened cement paste were analyzed by means of X-ray diffraction and scanning electron microscopy. The experimental results showed that with the increase of mixed material contents, the compressive strength decreased, while the content of hydroxyapatite was 5%, the strength reached highest. The ability of sulfate resistance was improved as appropriate amounts of hydroxyapatite, shell and calcium carbonate were added into the cement. When the content of hydroxyapatite was 5%, the corrosion resistance coefficient was1.24, reaching the best resistance to sulfate attack.
