This Part of this European Standard describes a method of test for determining the thermal compatibility of surface protection systems when applied to a standard concrete, by thermal cycling between 60 C and -15 C, including immersion in water b
20、ut without immersion in de-icing salt solution. It is one of a series of inter-related parts dealing with the thermal compatibility of repair products and systems.

25、hird in a series of five parts to assess the thermal compatibility of repair products and systems, comprising grouts, mortars and concretes and surface protection systems, used for the repair and protection of concrete structures. The method specified in this Part measures the effect of thermal cycl
26、ing, including wetting and drying but without de-icing salt immersion, upon surface protection and injection systems used as part of a repair product or system. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

31、nitions given in EN 1504-1 apply. 4 Principle The surface protection system is applied to a reference concrete test specimen prepared according to EN 1766. After curing of the surface protection system, the test specimen is subjected to freeze-thaw cycling with water immersion between (60 2) C and (
32、-15 2) C, but excluding immersion in saturated de-icing salt solution. Following the temperature cycling, visible defects are recorded and the adhesion of the surface protection system to the concrete substrate is determined by pull-off test (according to EN 1542). Thermal cycling is carried out eit
33、her continuously in a programmable climatic chamber or manually using a cooler, a water bath and an oven. 5 Apparatus 5.1Laboratory, maintained at the standard laboratory climate of (21 2) C and (60 10) % RH (see annex A). 5.2Mixer, for mixing the constituents of the mortar. Unless stated otherwise
34、by the manufacturer, use a forced action pan mixer. 5.3Concrete test specimens, of dimensions of 300 mm x 300 mm x 100 mm to EN 1766 and type as specified in prEN 1504-2. 5.4Core drilling machine with a diamond tool, internal diameter 50 mm as specified in EN 1542.

This equip
36、ment is used as the reference method. 5.7Programmable climatic cabinet, comprising an enclosed, insulated cabinet with heating, cooling and flooding equipment capable of maintaining temperatures of between (60 2) C and (-15 2) C. Adequate air and water motion for a homogenous temperature distributio
37、n in the cabinet shall be ensured. Inside shall be a temperature sensor to measure and record the temperature near the samples. The programmable climatic cabinet shall have a controller for the heating, cooling, flooding and emptying cycles. 5.8 Thermosetting resin for sealing the sides of the concr
38、ete test specimens to prevent penetration of water into the concrete. 6 Preparation of test specimens Three concrete test specimens (see 5.3) are required for each test, with one serving as a reference specimen. Prior to application of the surface protection system, all materials shall be stored in
39、the standard laboratory climate (see 5.1) for at least 24 h. The surface protection system shall be applied to the concrete test specimens in accordance with manufacturers instructions at the standard laboratory climate (see 5.1) or such alternative environments as may be specified for the intended
40、use. After application of the surface protection system, the samples shall be cured in accordance with the requirements of annex A. Before starting the test, all surfaces of the specimens except the 300 mm x 300 mm test face shall be coated with thermosetting resin (see 5.8) to prevent penetration o
41、f liquid into the side and rear of the concrete test specimen during the test, allowing full cure of the resin in accordance with the requirements for PC given in annex A. 7 Procedure After completing the preparation, thermal cycling shall then be carried out by one of the following methods : a) man
42、ual cycling using the cooler, water bath and oven (see 5.6), which is the reference method ; b) in a programmable climatic cabinet (see 5.7). Two of the prepared concrete test specimens are used for the thermal cycling, with the third specimen kept in the standard laboratory climate (see 5.1) for th
43、e duration of the test as a control. 7.1 Thermal cycling - reference method Thermal cycling takes place by manual transfer of the test specimens between the climatic cabinets (see 5.6). In each of the climatic cabinets the slabs are positioned upright, with a distance of at least 100 mm between the
44、slabs and of at least 50 mm from the slabs to the walls. The test specimens shall be subjected to the following test cycle, with one cycle lasting for 24 h : ? 2 h water storage at (21 2) C ; ? 4 h storage in air at (-15 2) C ; ? 2 h water storage at (21 2) C ; ? 16 h storage in air at (60 2) C. Dur
45、ing an interruption of the cycle storage, such as weekends, the test specimens shall be stored in the standard laboratory climate (see 4.1).

46、sitions of the test specimens in the storage tanks should be changed on a rotation basis, to compensate for any slight differences in temperature that might occur. The complete 24 h cycle shall be repeated for the number of cycles specified in prEN 1504-2. 7.2 Thermal cycling - Programmable climatic
47、 cabinet Automation of the reference procedure (see 7.1) can be achieved by use of a programmable climatic cabinet (see 5.7), following the temperature profile shown in Figure 1. The coated concrete test specimens are positioned upright, with a distance of a least 100 mm maintained between the slabs
48、 and of at least 50 mm from the slabs to the cabinet walls. One cycle lasts for 24 h and comprises the following stages : ? 2 h water storage at (21 2) C (including final emptying within a maximum of 15 min) ; ? 3 h cooling with air at (-15 2) C (the maximum permissible deviation from the linear tem
49、perature curve between 21 C and -15 C shall be 3 C) ; ? 4 h storage at (-15 2) C ; ? 15 min heating with water at (21 2) C (flooding within a maximum of 15 min) ; ? 1 h 15 min water storage at (21 2) C (including final emptying within a maximum of 15 min) ; ? 1 h 30 min heating with air at (60 2) C (permissible deviation from linear temperature curve between 21 C and 60 C shall be 3 C) ; ? 10 h air storage at (60 2) C ; ? 15
