14、EN 14117:2004) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. It has been drafted by Sub-Committee 8 “Products and systems for the protection and repair of concrete structures“ (Secretariat AFNOR). This European Standard

15、shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by March 2005. According to the CEN/CENELEC Internal Regulations, the national standards or

EN 14117:2004 (E) 4 1 Scope This document describes a test method for determining the time of efflux of cementitious injection products, based on the measurement of the time taken for a standard volume of the product to flow through a standar

18、dised cone (Marsh cone). This time of efflux is a measure of the viscosity of cementitious injection products. 2 Normative references The following referenced documents are indispensable for the application of this document.

21、llowing apply. 3.1 efflux time time taken by 1000 ml of cementitious injection product to flow through the flow cone 4 Test principle The test measures the time for a specified volume of fluid cementitious injection product to flow through a flow cone. 5 Apparatus 5.1 Flow cone (Marsh cone) made of

22、non corroding material, provided with a semicircular shaped sieve, with dimensions as shown in Figure 1. The discharge tube may be detachable, with a diameter of (4,8 0,1) mm, and a length of (51,0 0,5) mm. It is bolted or screwed to the lower part of the cone, in such a way that no discontinuity oc

23、curs between the cone and the discharge tube. The sieve shall have a mesh size of 2 mm. 5.2 Ring stand, or other device, capable of supporting the flow cone in a vertical, steady position, (150 10) mm above the upper face of the receiving container. 5.3 Receiving container, which allows the measurem

24、ent of a volume of injection product of (1 000 10) ml. 5.4 Level, to assure verticality of the flow cone. EN 14117:2004 (E) 5 5.5 Pouring container, which allows the measurement of a volume of injection product of (1 500 15) ml. 5.6 Stop watch, with an accuracy of 1 s. 5.7 Thermometer, with an accur

25、acy of 0,5 C. 5.8 Mixer, for cementitious injection product. 6 Sampling and preparation The temperature of the dry materials and mixing water shall be such that the temperature of the injection product at the start of mixing is (21 2) C. The injection product shall be mixed in accordance with the ma

26、nufacturer instructions. The time t 0is the time at the end of mixing. If it is required to test the mixture after a longer holding period, continue the mixing of the remaining portion at slow speed for the specified time, taking care to minimize evaporation. 7 Procedure The test shall be carried ou

27、t at a temperature of (21 2) C and a relative humidity of (60 10) %. The flow cone shall be firmly mounted in such a manner that it does not vibrate. The top shall be levelled to ensure verticality. The receiving container shall be levelled. Fill the flow cone with water and, 1 min before introducin

28、g the injection product, drain the water from the cone. Close the outlet of the discharge tube with a stopper. Introduce (1 500 15) ml of injection product into the cone through the sieve. Start the stop watch and simultaneously open the outlet. Stop the watch when (1 000 10) ml of the injection pro

29、duct has flowed through the cone. The measurements shall be repeated three times using a fresh mix each time. Before each measurement, the flow cone and receiving container shall be absolutely clean and free from injection product. If the efflux time has to be determined at time t 0 , the time inter

30、val between “t 0 “ and the beginning of the measurement shall not exceed 1 min. 8 Expression of results The results are expressed as the efflux time in s. 9 Test report The test report shall contain the following information: a) reference to this document; b) name and address of the test laboratory;
