23、efined level of consistence as measured using the flow table prior to the assessment of those properties which ar e used to characterize it.Consistence is a measure of the fluidity and/or wetness of the fresh mortar and givesa measure of the deformability of the fresh mortar when subjectedto a certa
24、in type ofstress. The consistenc e however is not directly associated with the manner i n which the fresh mortar handles when used by a craftsman. Normally there will be a linear corre lation between flow value, measured in accordance withthis testmethod, and the plunger penetration value measured i
25、n accordance with EN1015-4, for the same type ofmortar with increasing water content, but the slope will differ with different types of mortars.1 Scope # The following referenced documents are indispensable for the application of this document. For datedreferences, only the edition cited applies. Fo

27、ry mortar.EN 1015-2, Methods of test for mortar for masonry Part 2: Sampling of mortars and preparation of test mortars.3 PrincipleThe flow value is measured by the mean diameterof atest sample of the fresh mortar which has been placed on adefined flow table disc by means of adefined mould, and give
28、n a number of vertical impacts byraising the flow table and allowing it to fall freely through a given height.4 Apparatus4.1 A flow table , as described in Annex A, consisting of the following main parts: stand; rigid table plate and disc; horizontal shaft and lifting cam; lifting spindle.4.2 A trun
29、cated conical mould, made of stainless steel or brass, 60 mm 0,5 mm in height and withinternal diameter of100 mm 0,5 mm at the bottom and70mm0,5 mm at the top. The inside surfaceand the edges of the mould are smooth. The planes containing the top and bottom edges are at right anglesto its axis. The
30、minimum thickness of the mould wall is 2,0 mm.4.3 A tamper, consisting of a rigid, non-absorptive rod of circular cross-section, approximately 40 mm in diameter andapproximately200 mm long. The tamping face is flat andat right anglesto the length of thetamper. The massof the tamper is 0,250kg0,015 k
31、g.4.4 Calipers, capable ofmeasuring diameters up to 300mm with an accuracy of1mm. 4.5 Trowel. 4.6 Palette knife . $This European Standard specifies a method for determining the consistence of freshly mixed mortars(inthe following briefly referred to as fresh mortars) including those containing miner
32、al binders and bothnormal weight and lightweight aggregates, which is by means of the flow value.#$# BSI 2007$EN 1015-3:199945 Sampling, preparation and storage of test samples The fresh mortar for this test shall have a minimum volume of 1,5l and shall be obtained by reductionofthe bulk test sample
33、 (see EN 1015-2) using a sample divid er or by quartering. Ready to use mortars (factory-made wetmortars whichare retarded), and pre-batched air-lime/sand wetmortars when not gauged with hydraulic binders, shall be tested w ithin their specified workable life.Mortars that are made from dry constitue
34、nts and water shall be mixed in accordance withEN 1015-2unless otherwise specified.The length of the mixing period shall be measured from the moment all the constituents are introducedinto the mixer.Before testing,the batch shall be gently stirred byhand using a trowel or palette knife in510seconds
35、tocounteract any false setting etc., but without any additional mixing of the batch.Any deviation from the mixing procedure shall be noted. Two test samples shall be test ed.6 Procedure Before each test, wipe the disc and the inner surface and edges of the mould ( 4.2) clean with a damp cloth and l
36、et it dry. If the table has not been used within the last24h, operate itfor ten revolutions before use.Place the mould centrally on the disc of the flow table ( 4.1) and introduce the mortar in two layers, each layer being compactedbyat least 10 short strokes of the tamper ( 4.3) toensure uniform fi
37、lling of the mould.During filling, hold the mould firmly on the disc, using one hand.Skimoff the excess mortar with a palette knife and wipe the free area of disc clean anddry,being especiallycareful to remove any water from around the bottom edge of the mould. After approx imately15s,slowlyraise th
38、e mould vertically andspread out the mortar on the disc by jolting the flow table 15 times at a constant frequency of approximately one per second.Measure the diameter of the mortar in twodirections at right angles to one another using calipers ( 4.4). State the results in mm to the nearest mm.7 Cal
39、culation and expression of results Calculate the mean value of the two measurements. This mean value is the flow value for the test sample.If the individual flow values from the two test samples deviatefrom their mean value byless than 10 %,use this mean value as the flow value of the mortar. If the
40、 two individual flow values deviate from theirmean value by more than10%, repeat the test using further mortar from the reduced bulk test sample (see Clause 5 ) andifthe results deviate from the mean value by less than 10 % use the mean value fromthe repeat test as the flow value of the mortar. If t
41、he results differ by more than 10 % consider the measurementsunsatisfactory and take fresh test samples from the bulk test sample or laboratory preparedmortar and repeat the test. $# BSI 2007EN 1015-3:199958 Test reportThe test report shall include the following information:a) the number, title and

The flow table shall be mounted withoutany other support directly on a horizontal, non-sprung and non-plastic, stable base. NOTE 1A concrete p
46、edestal with a mass of more than 25 kg is suitable.The horizontal shaft withthe mounted lifting cam when turned at a constant velocity sh all raise the lifting spindle and the flow table by 10 mm/s 0,2 mm/s. The lifting cam shall be an even steady rising spiral constructed such that it will resume p
