These
22、normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated

EN 1504-1, Products and systems for the protection and repair of concrete structures Definitions, requirements, quality control and evaluation of conformity Part 1: Definitions. prEN 12189, Products and systems for the protection
24、 and repair of concrete structures Test methods Determination of open time. 3 Test methods This standard describes a method for the determination of the suitability of structural bonding agents applied using a spreader to a vertical or horizontal surface, referred to as the sag flow test. This stand
25、ard also describes a method for the determination of the suitability of injectable structural bonding agents for application between two surfaces, referred to as the squeezability test. 4 Equipment 4.1 Sag flow test 4.1.1 Sag flow board, in steel as depicted in Figure 1. 4.1.2 Temperature-controlled
26、 conditioning cabinet, adjustable to within 1 8C. 4.1.3 Thermometer measuring in degrees Celsius with 0,1 8C divisions. 4.1.4 Straightedge. 4.1.5 Timer. 4.1.6 Mould release agent. 4.2 Squeezability test 4.2.1 Wax papers, at least 400 mm square. 4.2.2 Flat steel plate, 6 mm thick and at least 400 mm
27、square. 4.2.3 Means of applying load of 150 N. 4.2.4 Timer. 4.2.5 Rule, graduated in mm. 5 Test procedure 5.1 Sag flow test 5.1.1 Conditioning Condition the resin and hardener components of the bonding agent and the sag flow board for at least 4 h at the test temperature of (212) 8C or an alternativ
28、e test temperature as required. 5.1.2 Procedure Clean the surface of the sag flow board. Mix the components of the sample in accordance with the manufacturers instructions. With the sag flow board in the horizontal position, spread the sample into each of the required channels, beginning with the sh
29、allowest channel. Round the material slightly above the top of the guides for each channel. With a straightedge, strike off the excess flush with the top surface of the guides for each channel, and flush with the lower end of the guides (see Figure 2). After all the required channels have been fille
30、d, allow the sag board to remain in a horizontal position for a further 30 s. Then, place the board gently into the vertical position, so that the board rests on the edge marked bottom (see Figure 1). Start the timer. The board shall remain in position throughout the test. All the required channels
31、should be filled within 10 min after the end of mixing. If the open time of the mixture, as measured by prEN 12189 is less than 15 min, the material should be tested in channels one at a time. At the end of the test (30 min unless otherwise reported), measure in millimetres the distance from the low
32、er end of the guides to the point of maximum flow for each thickness of interest. If the adhesive reaches the base of the sag flow board, the report should state that the sag was greater than 50 mm. 5.2 Squeezability test 5.2.1 Conditioning Condition the resin and hardener components of the bonding
33、agent as well as the plates for at least 4 h at the test temperature of (212) 8C or an alternative temperature as required. 5.2.2 Procedure Mix the components of the sample in accordance with the manufacturers instructions. 10 min after the completion of mixing, pour 300 cm3of bonding agent onto a s
34、heet of wax paper, placed on a hard level surface. The area occupied by the bonding agent should be as small as possible. Place a second piece of wax paper over the poured out bonding agent. A flat plate is placed on top of this second wax paper and a load of 150 N is applied centrally and verticall
35、y. The flat plate should be maintained parallel with the level surface. Maintain this load for 3 min, then remove the load and steel plate and measure the squeezed out diameter of the bonding agent. If the material squeezes out beyond the test area, the quantity of material should be reduced as appr
36、opriate.
