CMA PUBLISHES EIGHTH EDITION OF MASONRY MANUAL:
Article Date: 10 January 2008
 The Concrete Manufacturers Association (CMA) has published the eighth edition of its Concrete Masonry Manual, first published in 1987.
The manual incorporates SANS 2001-CMI Masonry Walling, one of the new series of standards that have replaced the former SABS 1 200 series. The new standards, as well as the new manual, will be used by designers, specifiers and other professionals in the construction industry.
Proposed changes to masonry standards in the application of the National Building Regulations, Part K Walls of SANS 10400, which are yet to be published, are also incorporated in the manual. Draft copies of the proposed changes to Part K are available from the SABS at half the normal price.
Comprising seven chapters and running to 109 pages, the manual refers to SANS and British standards on material specification.
Chapter 1 deals with the properties of concrete masonry units and subsequent chapters cover :
• Performance criteria for walling
• Modular coordination and design
• Building regulations
• Specification and construction details
• Schedule of site checks
• Quantities.
The manual is edited by civil engineer and former CMA director, John Lane, who is also the author of the Holcim Cement book on the manufacture of concrete masonry units. He is also joint author, with Fred Crofts, of a 300 page structural concrete masonry design guide.
