Formation of 3CaO.CaCl2.12H2O, which is a very unstable complex salt, in deteriorated concrete attacked by calcium chloride has been regarded as a main cause for the deterioration of cement concrete. In this study, a slurry from Ca(OH)2-CaCl2-H2O system was examined under different conditions. X-ray diffraction (XRD) analysis indicates that 3CaO.CaCl2.12H2O cannot be detected in the original slurry, but is detected after acetone washing of the slurry. 3CaO.CaCl2 12H2O disappears when the acetone-washed sample is air-dried at 20°C and 20% relative humidity. Thus, cautions should be taken during the preparation of samples during the examination of calcium chloride attacked concrete.
