Tentative Specification for High Alumina Cements

Foreword.-The Committee desire to state that in preparing this Tentative Specification they have given consideration to very many points which for various reasons are not embodied therein. In particular, the inclusion of manufacturing by sintering and the addition of gypsum during grinding were matters which were very carefully reviewed. There was, however, no evidence before the Committee that it was the practice of any manufacturers in this Country at the present time to produce high alumina cement by sintering, or to add gypsum during grinding, and it was considered undesirable to legislate for material not in accordance with present day manufacturing practice.
