Introduction

Aspects of prEN 197-1 are reviewed from the perspective of a concrete producer. In many cases the specifier is better advised to specify direct requirements from the concrete instead of specifying the cement type and class. There is no need to specify cement strength sub-class and the need to specify the cement strength class is mainly in prescribed mixes. Whilst there is a case for specifying the permitted cement types, concrete producers would prefer to have a list linked to mix limitations and exposure class in an informative annex to the European concrete standard.
