Is High-alumina Cement a Satisfactory Structural Material?

Long-term behavior of high-alumina cement concrete is described with an emphasis on the loss of strength due to conversion. Failures in various countries, especially in England, are reviewed. The status of the cement in a number of countries is reported, and it is concluded that there are no grounds for including the cement in Canadian standards.The current discussion on the need for a standard for high-alumina cement concrete in Canada makes the subject of the structural behavior of this material topical. For this reason, experiences in other countries, and especially the recent problems in England, may be of interest.
