26、 (E) 4 1 Scope This European Standard describes the determination of the rate of cure of cold applied joint sealants indicated by the build-up of the tensile modulus during the cure. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and
27、are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13880-12, Hot applied joint sealants Part 12: Test method for the manufacture of concrete test blo
28、cks for bond testing (recipe methods) EN ISO 6927, Buildings and civil engineering works Sealants Vocabulary (ISO 6927) EN ISO 8340, Building construction Sealants Determination of tensile properties at maintained extension (ISO 8340) 3 Terms and definitions For the purposes of this document, the te
29、rms and definitions given in EN ISO 6927 apply. 4 Principle The rate of cure of a cold applied joint sealant is determined as the relation between the tensile modulus at any time during cure and after complete cure of the test specimen. 5 Apparatus and materials 5.1 Concrete supports in accordance w
30、ith EN 13880-12 for the preparation of the test specimens, of dimensions as shown in Figure 1. Two concrete supports shall be used for each test specimen. 5.2 Spacers, (Figure 1) of dimensions 12 mm 12 mm 12,5 mm (Figure 1) for the preparation of test specimens. Two spacers shall be used for each te
31、st specimen. 5.3 Anti-adherent substrate for the preparation of the test specimens, on which the sealant does not adhere. 5.4 Tensile test machine capable of extending the test specimens at a rate of (5,5 0,5) mm/min. 6 Preparation of test specimens 6.1 Assemble two concrete supports (5.1) and two s
32、pacers (see 5.2) in accordance with Figure 1 and set up on the anti-adherent substrate (5.3). For the test six specimens are needed. 6.2 Follow the instructions of the sealant manufacturer whether a primer is to be used. 6.3 Condition the concrete supports, the spacers and the sealant for 4 h at (23
33、 2) C. Fill the volume between the concrete supports and spacers with sealant. 6.4 For multi-component cold applied joint sealants, thoroughly mix appropriate quantities of base component with curing agent following the manufacturers instruction. One-component joint sealants can be applied directly
34、from the pack. BS EN 141871:2017EN 14187-1:2017 (E) 5 The following precautions shall be taken: avoid the formation of air bubbles by filling from the bottom; ensure that no sealant is running out at the bottom; trim the sealant surface so that it is flush with the faces of the support and spacers.

Three of the test specimens are
36、 kept at the temperature of (23 2) C and (50 5) % relative humidity, see Table 1.

37、 6 After any time when the rate of cure has to be determined and according during the process of cure remove the spacers of the test specimens and place them in the tensile test machine and extend them of 100 % of the original width at a rate of (5,5 0,5) mm/min. Record a force/strain diagram. In th
38、e same way the reference test specimens are tested after completing conditioning method A or B. When method B is used, the reference test specimens will be tested after conditioning for 24 h at (23 2) C and (50 5) % relative humidity. 8 Calculation and expression of results Calculate the rate of cur
39、e, expressed in percentage as relation of the tensile modulus at 100 % extension of the test specimens to the reference test specimens, using the following equation: 12= 100MMMwhere M is the rate of cure, expressed in percent (%); M1is the arithmetic mean of the tensile modulus (100 % extension) of
40、the test specimen tested at any time during cure, expressed in newtons per square millimetre (N/mm2); M2is the arithmetic mean of the tensile modulus (100 % extension) of the reference test specimen after complete cure, expressed in newtons per square millimetre (N/mm2). 9 Test report The test repor
41、t shall include the following information: a) reference to this European Standard; b) name and type of the cold applied joint sealant; c) batch of sealant from which the test specimens were produced; d) rate of cure of the cold applied joint sealant; e) any deviations from the specified test conditi
42、ons; f) date of test.
