Background to Concrete Manufacturers Association (CMA) (content)
The CMA was established in 1972.
It comprises the national co-ordinating body of manufacturers of precast concrete masonry, concrete block paving, concrete roof tiles, concrete retaining blocks, precast floor slabs and concrete pipes and culverts.
Producers and suppliers of materials and equipment used by its members support the CMA.
It is responsible for representing the concrete masonry, paving, roof tile, retaining block, floor slab and pipe industries in all matters relating to the manufacture and use of its members's products.
Aims & Objectives
The Associations main aim is to promote the increased and most effective use of segmental block paving, concrete roof tiles, concrete retaining blocks, floor slabs, concrete masonry and concrete pipes by architects, engineers, specifiers, contractors and end users in a professional manner for the benefit of all.
The correct use of the products from a design and application point of view is critical to the performance, and the Association has produced manuals and brochures to help achieve this.
To further achieve this aim the CMA offers:
- An advisory service
- Technical lectures and symposia
- Education and training courses
- Research feedback
The CMA is concerned with quality. Producer members must comply with one of the following:
