Page 3 EN 1015-10:1999 1 Scope This European Standard specifies a method for determining the dry bulk density of hardened mortars. It is applicable to lig
20、htweight and general purpose and thin layer mortars using specimens of regular shape. 2 Normative references Part 1: Rendering and plastering mortar with inorganic binding agents. Part 2: Masonry mortar. EN 1015-2, Methods of test for mortar for masonry Part 2: Bulk sampling of mortars and preparati
21、on of test mortars. EN 1015-3, Methods of test for mortar for masonry Part 3: Determination of consistence of fresh mortar (by flow table). EN 1015-11, Methods of test for mortar for masonry Part 11: Determination of flexural and compressive strength of hardened mortar. 3 Principle The dry bulk dens
22、ity of a given specimen of hardened mortar is determined as the quotient of its mass in oven dried condition, and the volume which it 4 Symbols m s,dry is the oven dry mass of specimen of hardened mortar, in kilograms (kg); V s is the volume of specimen of hardened mortar, in cubic metres (m 3 ). 5
23、Apparatus 5.1 A weighing instrument, accurate to 0,1 % of the total mass of the specimen. 5.2 A ventilated oven, capable of maintaining a temperature of 708C 58Co r6 08 C 58 C. 5.3 Moulds, as described in EN 1015-11. 6 Sampling, preparation and storage of test samples The fresh mortar for this test
24、shall have a volume of not less than 50 times the maximum aggregate particle size, and in no case less than 50 ml or 1,5 times the quantity needed to perform the test, whichever is the greater. It shall be obtained either by reduction of the bulk test sample (see EN 1015-2) using a sample divider or
25、 by quartering or by preparation from dry constituents and water in the laboratory. The flow value of the mortar in the bulk test sample shall be determined in accordance with EN 1015-3 and reported. Laboratory mixed samples shall, before testing, be brought to a defined flow value as specified in E
26、N 1015-2. Ready to use mortars (factory-made wet mortars which are retarded), and pre-batched air-lime/sand wet mortars when not gauged with hydraulic binders, shall be tested within their specified workable life. The length of mixing period shall be measured from the moment all constituents are int
27、roduced into the mixer. Before testing, the batch shall be gently stirred by hand using a trowel or palette knife in 5 s to 10 s to counteract any false setting etc., but without any additional mixing of the batch. Any deviation from the mixing procedure shall be noted. A test sample shall comprise

30、EN 1015-2). 7 Procedure Dry the specimen in the oven at a temperature of until the constant mass is reached. For samples with organic constituents, e.g. expanded polystyrene aggregate, use a drying temperature of 608C 58C. The specimen is considered to have reached constant mass if two consecutive w
31、eighings 2 h apart during the drying, do not differ by more than 0,2 % of the mass of the dry specimen. Record the mass of the specimen, m s,dry in kg to the nearest 0,1 %. 8 Calculation and expression of results Calculate the dry bulk density of each mortar specimen as the ratio of the recorded mas
