CEN/TC 104

Concrete and related products

CEN/TC 104 deals with the standardisation of provisions for concrete and related products, in particular with respect to properties and requirements for: - fresh and hardened concrete; - production and delivery of fresh concrete; - constituent materials of concrete, e.g. mixing water, additions and admixtures; - sheaths for prestressing tendons; grout for prestressing tendons; - fibres for use in concrete; - execution of concrete structures; - production and execution of sprayed concrete; - products for the protection and repair of concrete structures. Additionally relevant test methods and provisions for the assessment of conformity for the products and procedures mentioned above are standardized. Not covered by the scope of TC 104 are: - the constituent materials; aggregate (see CEN/TC 154), Pigments (see CEN/TC 298) and Cement (see CEN/TC 51); - the design of concrete structures and components (see CEN/TC 250/SC 2); - precast concrete products (see CEN/TC 229); - prefabricated autoclave aerated and no-fines light weight concrete components (see CEN/TC 177).

P member

CEN/TC 229

Precast concrete products

Standardization of precast concrete products (plain, prestressed, or reinforced or composite steel/concrete) covering terminology, performance criteria, preferred shapes and dimensions, tolerances, relevant physical properties special test methods, special features due to transport, erection and connections, not duplicating the work of other TCs, referring however, to concrete material properties covered by TC 104, properties for reinforcing steel covered by ECISS/TC 19, all general design and structural aspects covered by the Eurocodes, particularly Eurocode 2, and excluding products covered by other technical committees (including TC 125, 128, 164, 165, 177, 178...)

P member

ISO/TC 71

Concrete, reinforced concrete and pre-stressed concrete

Standardization of the technology of concrete, of the design and construction of concrete, reinforced concrete and pre-stressed concrete structures, so as to ensure progressive development both in quality and in price reduction; and of definitions and terms, as well as testing procedures, to facilitate international exchange of research work.
