Prfung von Festbeton Teil 2: Herstellung und Lagerung von Probekrpern fr Festigkeitsprfungen

European Standard EN 12390-2 : 2000 has the status of a DIN Standard.

A comma is used as the decimal marker.

National forewordThis standard has been prepared by CEN/TC 104 Concrete (performance, production, placing and compli-ance criteria) (Secretariat: Germany), SC 1 Concrete (performance, production, placing and compliancecriteria).The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Buildingand Civil Engineering Standards Committee), Technical Committee 07.05.00 Prfverfahren fr Beton.It should be noted that the conditions of curing the concrete specimens customary in Germany differ fromthose specified in subclause 5.5.3 (see National Annex).

National Annex NA (informative)Curing of concrete specimens when testing compressive strength and modulus ofelasticityNA.1 GeneralThis national annex describes the conditions customary in Germany for the curing of concrete specimensintended to be used for compression tests and when testing the modulus of elasticity.It is essential that the test parameters given in subclause NA.2 are adhered to, use of the parameters givenin footnotes 1) and 2) being recommended.

NA.2 Curing conditionsAfter preparation, the specimens shall be conditioned in moulds in a closed room at a draught-free location,protected from loss of moisture (e.g. by covering with polyethylene sheeting), for (24 t 2) hours at atemperature of 15 C to 22 C 1). During hardening, the environment shall be vibration-free.After (24 t 2) hours, the specimens shall be demoulded, placed on gratings and cured for six days in waterat a temperature of (20 t 2) C or, alternatively, in a cabinet at a temperature of (20 t 2) C and a relativehumidity exceeding 95 %.Seven days after preparation, the specimens shall be removed from the water cabinet, placed on gratingsand stored in a closed room at a draught-free location at a temperature of 15 C to 22 C 2).

1) A temperature of (20 t 2) C is recommended.2) A temperature of (20 t 2) C at a relative humidity of (65 t 5) % is recommended.
