The CAA

The CAA is a trade association founded in 1963 and representing over 85% of UK admixture manufactures who are committed to offering the highest standards of product quality and support.

Admixtures are specially formulated products that are added in small amounts to concrete, mortar or grout during the mixing process in order to modify the concrete properties in the plastic and / or hardened state.

These varied and versatile products provide enhanced concrete quality, improved durability and deliver cost-benefits to both the producer and the user.

The durability, sustainability and environmental profile of concrete can all be enhanced by admixture use.

CAA reference cement complying with the requirements of EN 480 is available from the CAA. Contact the CAA secretary on info@admixtures.org.uk for details or see Admixture Information Sheet AIS 4 on the CAA publications page.

Several European Admixture standards will be revised in 2009. EN 934 parts 2 and 4 are already published, part 3 has passed final vote and EN 480 parts 10 and 13 revisions are also expected in 2009.
EFCA the European Admixture Federation is working on a test method that would allow Viscosity Modifying Admixtures for segregation resistance in SCC to be standardised within the EN 934 series. The draft document will be presented to CEN TC104/SC3 late in 2009
Demonstrating the sustainability of concrete is of prime importance to the concrete industry and the CAA has contributed to the ‘Concrete Industry Sustainable Performance Report 2009’ giving a sustainability profile for 2007 and available for free download from the CAA publications page. Further Sustainability information for concrete can be found on the UK Concrete Industry ‘Sustainability Web Site’ www.sustainableconcrete.org.uk.
An updated report will be available early in 2010 giving concrete industry 2008 profiles and this will be added to the CAA publications page when available.
Information on the ECO2 of concrete constituents and of concrete can be found in a series of sheets available from www.sustainableconcrete.org.uk. See download tables at: http://www.sustainableconcrete.org.uk/main.asp?page=210
The CAA has produced a number of Admixture Environmental Sheets (AES) including Environmental Product Declarations. In addition AES 13 gives a 2008 ‘Sustainability Profiles’ for the admixture industry and there is information on ‘Admixtures, EcoPoints and the Green Guide’ in AES 12. These are all available for free download from the CAA Publications Page.
CAA can provide speakers on admixture technology and other admixture related topics for training events and lectures. Some training information is also available on the websites of our members including: http://www.sika.co.uk
