18、006 (E) 4 1 Scope This European Standard specifies a method for carrying out a sustained tensile load test on a reinforcing steel bar (rebar) anchored in a concrete block. The test is performed to determine the tensile creep under standard conditions, or under maximum service temperature conditions
19、recommended by the manufacturer. The test applies to products based on synthetic resins or hybrid synthetic resin/hydraulic cements. It does not include those products intended to be used as grout around tendons used for the prestressing of concrete. 2 Normative references The following referenced d

22、e displacement of the rebar relative to the concrete test piece over different periods of time. The test is performed using blocks of concrete type C(0,40) in accordance with EN 1766. The test is carried out at standard laboratory temperature of (21 2) C or such other temperature as specified by the
23、 manufacturer. 4 Apparatus The following apparatus is required. 4.1 One mixer for concrete. 4.2 One mixer for the product to be tested. 4.3 Moulds for the preparation of concrete blocks of minimum dimensions 400 mm x 400 mm x 250 mm. 4.4 One concrete vibrator, 25 mm diameter 4.5 One rotary percussiv
