Cylinder Moulds

Test procedures require that specimens are cast in a number of standard sizes convenient for compressive and flexural strength determination. The engineering tolerances specified for moulds are very stringent and the internal finish of the surface must be of a high order to comply with the recommendations laid down in many international standards. Moulds must not deform during manufacture of concrete specimens if the specimen dimensions are to be maintained.

• ASTM C39, C192
• AASHTO T23, T126
