CMA PUBLISHES LEAFLET ON PRESTRESSED SLABS FOR BUILDING RESERVOIRS:
Article Date: 31 October 2008
South Africa has entered a new era in building technology with the introduction of yet another application for prestressed hollow-core slabs, in this instance for the construction of reservoir walls and roofs.
To ensure that local engineers and specifiers have access to the new technology, the Concrete Manufacturers Association (CMA) has published a four-page leaflet on the subject.
The leaflet is based on SA’s first reservoir built using slab technology. Completed earlier this year, it is situated in Lindley, Free State. The document includes photographs and engineering drawings of the Lindley project and it describes the construction process and the materials used.
CMA director, John Cairns, says prestressed slab technology offers an advantage in quicker construction and solves the problem of skills shortages, especially in rural areas. The slabs used on the Lindley project were only partially hollow-core as the bottom 1.2m section of the 4.5m panels were cast in solid concrete to provide additional shear strength.
Copies of the leaflet are obtainable from the CMA. Contact Pam on 011 805-6742 or on main.cma@gmail.com . It can also be downloaded from the CMA website www.cma.org.za.
