ABSTRACT
The CEN Committee has completed a European pre-Standard for Masonry cement specification, ENV 4131 [2], and a full European Standard for test methods, EN 413-2 [3]. The British Standard for Masonry cement, BS 5224 [4], is being revised to take account of these developments. Table 1 compares the properties of the old BS 5224 with that of class MC 12.5 cement in the ENV which is that closest to the traditional UK Masonry cement.
