THE CRAZING OF CONCRETE MADE WITH WHITE CEMENT

Tests have been made over a six-year period on more than ninety columns made from white cement concrete. The results support the hypothesis that concrete always crazes, but that often this crazing cannot be detected by the unaided eye. A number of factors were considered, including the use of various surface treatments, but few were found to have any significant long-term effect on the incidence of crazing. The most important parameter dictating the degree of crazing is the type of form face, dense smooth surfaces leading to much more visible crazing than more open-textured, permeable formwork. The use of mixes with high cement contents also increases the severity of this aesthetic defect. /Author/TRRL/
