15、 standard, the terms defined in DIN EN 13318 apply, as well as the following. 3.1 hard aggregate a mixture of particularly hard natural stone or slag and/or metal particles, fused aluminium oxide and silicon carbide, mixed at the production plant along the lines of DIN EN 12620 4 Hard aggregate grou
16、ps Hard aggregate is classified into the following groups, based on the type of material contained therein: Group A (generally): Natural stone and/or dense slag, or mixtures thereof with Group M and/or KS aggregate Group M: Metal Group KS: Fused aluminium oxide and silicon carbide 5 Requirements 5.1
17、 General Hard aggregate shall not contain any substances which have an adverse effect on the setting, curing, surface quality and durability of the wearing screed. In addition, the information given in DIN V 20000-103 and Annex G of DIN EN 12620:2003-04 shall be taken into consideration. DIN 1100:20
18、04-05 5 5.2 Particle size distribution The particle size distribution of Group A and Group KS aggregate shall be specified by the manufacturer, maintained within the tolerances given in table 1, in deviation from DIN EN 12620. The particle size distribution of Group M aggregate shall also be specifi
19、ed by the manufacturer, maintained within the tolerances agreed upon. Table 1 Tolerances for hard aggregate particle size distribution Tolerance for percents passing, as a percentage by mass, for particle size groups Sieve size, in mm 0/5 0/4 0/2 5,6 (5) 5 4 10 5 2 10 10 5 1 5 5 5 0,25 3 3 3 0,125 3
20、 3 3 0,063 2 2 2 5.3 Bulk density The bulk density of hard aggregate shall be specified by the manufacturer and be within 10 %. 5.4 Abrasive wear When testing screed mortar prepared according to the manufacturers specifications, the values for the abrasive wear of hard aggregate shall not exceed tho
21、se specified in table 2. The manufacturers specifications shall include the cement-to-aggregate mix ratio, the water/cement ratio and the working consistency. Table 2 Abrasive wear Hard aggregate group Abrasion quantitya, in cm3/50 cm2A 5,0 M 3,0 KS 1,5 aMean result when testing as in subclause 6.4.
22、 5.5 Strength The manufacturer shall give the compressive and flexural strength values determined during initial type testing of the screed mortar used to determine abrasive wear (cf. subclause 5.4). DIN 1100:2004-05 6 5.6 Fire behaviour Only hard aggregate which meets the requirements for one of th
23、e classes specified in DIN EN 13501-1 may be used. Hard aggregate may be attributed to class A1 without testing as long as the percentage by mass or by volume (whichever is greater) of organic substances does not exceed 1 %. 6 Testing 6.1 General The properties of Group A and Group KS aggregate, and
24、 where expedient those of Group M aggregate, shall be tested as in DIN EN 12620. 6.2 Particle size distribution The particle size distribution of Group A and Group KS aggregate shall be determined as in DIN EN 933-1, while the determination of the particle size distribution of Group M aggregate shal
25、l be along the same lines. 6.3 Bulk density Bulk density shall be determined as in DIN EN 1097-3 and the results given in kg/dm3. Test containers having different capacities than those specified in the above-mentioned standard may be used if values obtained using such containers are available for co
26、mparison with results obtained using the standardized containers. 6.4 Abrasive wear Abrasive wear shall be tested on three plates or cubes having a test surface edge length of (71 1,5) mm and made from screed mortar prepared according to the manufacturers specifications. The test specimens are to be
27、 compacted on a vibrating table as in DIN EN 196-1, covered by a glass plate and then conditioned for two days in the mould at (20 1) C and a relative humidity of at least 95 %. Specimens shall then be demoulded and then conditioned at DIN 50014-20/65-2 standard atmosphere for 21 more days. Before t
28、esting, dry the specimens at (105 5) C until constant mass1)has been reached. Then, carry out testing as in DIN 52108 on the upper test surface. Include the specimen age at the time of testing in the results. The test surface is to be pre-ground for four test cycles (cf. DIN 52108). Normally, abrasi
29、ve wear is to be determined on the basis of loss in volume. Determining abrasive wear on the basis of loss in thickness is only useful if the density of the layer that is subject to wear cannot be established. 6.5 Strength Flexural and compressive strength shall be carried out on the screed mortar u
30、sed for testing abrasive wear (cf. subclause 5.4), using three test specimens 40 mm 40 mm 160 mm in size. Specimens shall be compacted on a vibrating table as in DIN EN 196-1 and conditioned as specified in subclause 6.4 of the present standard. Testing is to be carried out on specimens having an ag
31、e of 28 days. 1) Constant mass is deemed to have been reached when two subsequent weighings, 24 hours apart, produce results which differ by no more than 0,1 %. DIN 1100:2004-05 7 7 Inspection 7.1 General Whether or not the requirements specified in clause 5 have been met shall be established by mea
32、ns of factory production control and third-party inspection carried out in accordance with DIN 18200. 7.2 Factory production control Every ten production days, the manufacturer shall determine the particle size distribution as in subclause 6.2 and bulk density as in subclause 6.3, and record the res
33、ults. 7.3 Third-party inspection Third-party inspection shall be performed by a competent inspection body or test laboratory on the basis of an inspection contract.2)First, an initial inspection shall be performed before production of hard aggregate is assumed; this inspection shall involve testing
34、as in subclauses 6.2 to 6.5 and checking all characteristic values documented by the manufacturer as part of factory production control. Every two years, the results of factory production control shall be checked, and a routine inspection, comprising testing as specified in subclauses 6.2 to 6.5, sh
35、all be performed. The results of product testing shall comply with the requirements of this standard. In addition, the inspection body is to establish whether or not these results correspond to the results reported as part of factory production control. 8 Designation Hard aggregate shall be designat
36、ed by the letters representing the group to which it belongs (cf. clause 4), and the smallest (d) and largest (D) sieve sizes (cf. DIN EN 12620). EXAMPLE Designation of Group M hard aggregate (i.e. of metal) (M) with the smallest sieve size being 0 mm and the largest sieve size being 4 mm: Hard aggr
37、egate DIN 1100 M 0/4 9 Marking Hard aggregate which complies with this standard and which is subject to inspection in accordance with this standard shall be supplied in sacks of a defined gross nominal weight3)(e.g. 25 kg) marked with the designation as in clause 8, as well as any markings required
38、by DIN 18200. 2) Organizations which are deemed competent for inspecting aggregate include inspection bodies and test laboratories which have been recognized by the Lnder building inspectorate, and the Institut fr Baustoffprfung und Fubodenforschung (Institute for Testing Building Materials and for
39、Flooring Materials Research) in Troisdorf. A list of recognized inspection bodies and test laboratories is maintained by the Deutsches Institut fr Bautechnik (German Institute for Building Technology) and is published in its proceedings by Verlag Ernst & Sohn in Berlin. 3) Deviations of up to 2 % from the gross nominal weight are permitted.
