EN 1739:2007 (E) 3 Foreword This document (EN 1739:2007) has been prepared by Technical Committee CEN/TC 177 “Prefabricated reinforced components of autoclaved aerated concrete or light-weight aggregate concrete with open structure”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2007, and conflicting national standards shall be withdrawn at the latest by October 2007. This document supersedes EN 1739:1998. In order to meet the performance requirements as laid down in the product standards for prefabricated reinforced components of autoclaved aerated concrete and of lightweight aggregate concrete with open structure, a number of standardized test methods are necessary. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 1739:2007 (E) 4 1 Scope This European Standard specifies methods of determining the shear strength for in-plane forces of joints between prefabricated components made of autoclaved aerated concrete (AAC) according to prEN 12602 or lightweight aggregate concrete with open structure (LAC) according to EN 1520. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 678, Determination of the dry density of autoclaved aerated concrete EN 679, Determination of the compressive strength of autoclaved aerated concrete EN 992, Determination of the dry density of lightweight aggregate concrete with open structure EN 1353, Determination of moisture content of autoclaved aerated concrete EN 1354, Determination of compressive strength of lightweight aggregate concrete with open structure 3 Principle The shear strength for in-plane forces of longitudinal joints between two adjacent prefabricated AAC- or LAC-components or sections thereof is determined by applying an in-plane shear force parallel with to the joint. The load is increased continuously or in steps until failure of the joint. The load-displacement diagram and the failure load are determined. The shear strength is determined from the failure load. 4 Apparatus a) saw for cutting components and test specimens; b) compression testing machine or a hydraulic jack, capable of applying a compressive load without shock continuously or in steps. The precision of the compression testing machine or of the hydraulic jack and of the load indication shall be such that the failure load can be determined to an accuracy of ± 3 %. The measuring range shall be such that the failure load is higher than one-tenth of the range used; c) callipers and/or rule, capable of measuring the dimensions of the test specimens and the joints to an accuracy of 1 mm; d) loading frame and/or devices (e.g. steel plates, flat steel bars, steel rollers, soft fibre board) according to Figures 1, 2, 3 or 4 (or Figures 5 or 6, for alternative tests) for transmitting the load and support reactions to the test specimen; e) dial gauge or a displacement transducer with a reading accuracy of 0,01 mm for measuring the relative displacement between the loaded and the supported part of the test specimen.
EN 1739:2007 (E) 5 5 Test specimens 5.1 Sample The sample for the preparation of the test specimens shall be taken in such a manner that it is representative of the product to be investigated. In the case of AAC, the direction of rise of the mass during manufacture shall be marked on the components. 5.2 Shape and size of test specimens The test specimen consists of two connected parts of prefabricated reinforced components with the actual thickness t of the component and a length of l = 150 mm. The width of one part is w1 = 100 mm and the width of the other part is w2 = 200 mm, the total width of the specimen is then w = 300 mm plus the thickness of the joint, see Figures 1 and 2. If the joint system is mechanical, e.g. nails and plates or similar or toothed joints, the dimensions may be increased, to ensure space for the tooth or mechanical connections, as long as the ratio between the width and the length is 1 (e.g. w = l = 600 mm), see Figures 3 and 4. 5.3 Number of test specimens A test set shall consist of at least three test specimens. 5.4 Preparation of test specimens AAC shall be allowed to cool for at least 2 d after autoclaving before assembling of the two parts. LAC test specimens shall be at least 21 d old before assembling the two parts and at least 28 d at testing. Before jointing, length, thickness and width of the parts to be connected shall be measured. The shape and dimensions of the longitudinal faces adjacent to the joint (e.g. tongue and groove) shall also be determined. For a mechanical jointing system dimensions and material properties of all parts shall be indicated. If the parts to be connected are frozen or cold, they shall be stored with sufficient space between each other at room temperature for at least 2 d before jointing. In the case of a grouted joint the test specimens shall be assembled as shown in Figures 1 or 2. If the joint system is mechanical, e.g. nails and plates or similar, the two parts shall be joined together dry, without grouting (see Figures 3 or 4). There shall be at least two mechanical fixings or grouted dowels along such a joint. Defined tolerances
