THE STORY OF H.A.C.

This article gives a brief account of structures which have failed through the use of high alumina cement since the introduction of this material from France some 50 years ago. The French government, aware of certain dangers in using high alumina cement, imposed a number of restrictions on its use before the second world war. The German government, in 1962, banned its use in a variety of situations. Following the collapse of the roofs of two London schools in 1974, the British building research establishment began to investigate high alumina cement. Initial results have shown that the loss of strength of beams constructed with the material was due to conversion followed by sulphate attack - leading to disruption of the concrete. The full report is expected in February 1975. At the present time, the D.O.E. has initiatd an inspection of buildings using high alumina cement, and have issued recommendations as to its future use. /TRRL/
