This European Standard shall be

15、 given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by December 2002. It has been prepared by sub-committee 8 “Products and systems for the protecti

16、on and repair of concrete structures“ the secretariat of which is held by AFNOR. This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It describes a test method for determining the workability of thixotropic repair mortars.

17、 It is one of inter-related parts dealing with the workability of repair grouts, mortars and concretes.

25、 the purposes of this European Standard, the following terms and definitions contained in EN 1504-1 and prEN 1504-3 1apply. 4 Principle The workability of the thixotropic mortar is measured by the spread of a defined test sample when placed on a flow table, with the spread being achieved by a set nu

26、mber of jolts, whereby the platen of the table is raised slightly and then dropped back to the resting position. The method is based on EN 1015-3. NOTE Trowel-grade repair products are normally mortars, applied by hand to horizontal, vertical or overhead surfaces using appropriate compaction and lev

27、elling tools. 5 Equipment 5.1 Mortar mixer, in accordance with EN 196-1, or concrete mixer, (forced action pan mixer). 5.2 Tamper consisting of a round, non-absorptive rod, (40 1) mm in diameter and with a length of (200 10) mm. The tamping face shall be a flat, square end. The mass of the tamper sh

28、all be (0,250 0,015) kg. 5.3 Flow table and truncated conical mould as described in annex A of EN 1015-3:1998 and shown in Figure 1. 5.4 Calipers capable of measuring diameters up to 300 mm with an accuracy of 1 mm.1Under preparation.EN 13395-1:2002 (E) 5 5.5 Standard laboratory climate of (21 2) C

29、and (60 10) % RH. 5.6 A stop watch or stop cock accurate to 1 s. 6 Preparation and storage of test samples All materials shall be conditioned in the standard laboratory climate (5.5) for a period of not less than 24-h prior to mixing. Unless otherwise instructed by the manufacturer, use the followin

30、g mixing technique for preparing the specimens. For PCC and CC mortars, use the mortar mixer (5.1) set to a low speed, pouring the gauging liquid to the bowl and adding the dry ingredients, mixing for a total period of two minutes after addition of all ingredients. Where manufacturers instructions p

31、reclude use of part bags of material, a concrete mixer (5.1) or other method recommended by the manufacturer shall be used. NOTE It has been found that certain types of repair mortar can foam excessively under the action of the mortar mixer specified in EN 196-1. An alternative is to use a concrete

32、mixer (5.1). The air content, strength and density of the HC and PCC mixes should normally be determined to characterise the mortar under test. 7 Procedure The flow value shall be determined in the standard laboratory climate. The sample shall be tested after (10 5) min, (30 5) min or at other perio

33、ds agreed with the manufacturer. Prior to testing, the mortar shall be remixed for a period of (20 2) s. Two samples shall be tested at each time interval. NOTE In addition, the flow value for the mortar can be determined at other temperatures for special applications. Before the start of each test,

34、 the platen of the flow table and the inner surface and edges of the conical mould shall be wiped clean with a damp cloth. If the table has not been used within the last 24 h, operate for ten revolutions of the shaft to check for function. To measure the flow value, the conical mould shall be placed

35、 centrally on the platen of the flow table and the mortar introduced in two layers, each being compacted by short strokes of the tamper to ensure uniform filling of the mould is achieved. During filling, the conical mould shall be held firmly down on the platen to prevent loss of material from under

36、 the mould. Skim off the excess mortar and wipe clean the free area of the platen, being especially careful to remove any water from around the bottom edge of the conical mould. After 30 s, slowly raise the mould vertically and, by turning the shaft, jolt the platen 15 times at a frequency, as near

37、as possible, to one of one drop per second. 8 Expression of results The diameter of the mortar on the platen, which will have spread as a result of the energy from the drop action, shall be measured in two directions at right angles to one another using the calipers. Record the result to the nearest

38、 1 mm and calculate the mean value of the two tests at each time interval. The flow value is equivalent to the mean result. If the two values for a batch of mortar differ by more than 10 % from their mean Flow Value, two additional samples shall be taken and tested.EN 13395-1:2002 (E) 6 9 Test repor
