The British Standard Specification for Portland Cement Again Needs Revision. - Othe National Standar

The British Standard Specification for Portland cement was first issued in 1904 by
the Engineering Standards Committee (now the British Engineering Standards Association, incorporated in 1918), a body, as its name implies, entrusted with the framing of engineering standards of all kinds, and supported by all the chief Engineering Institutions of this country. This specification was drawn up by a representative committee, 25 in number, consisting of engineers, contractors and cement manufacturers, etc., under the chairmanship of the late Sir William Mathews, the well-known dock and harbour engineer.
