Lightweight concrete wallboards - unreinforced

BS EN 12696:2000 混凝土中钢的阴极保护

This European Standard specifies performance requirements for cathodic protection of steel in atmospherically exposed concrete, in both new and existing structures. It covers the atmospherically exposed parts of building and civil engineering structures, including normal reinforcement and prestressed reinforcement embedded in the concrete. It is applicable to uncoated steel reinforcement and to organic coated steel reinforcement. This European Standard does not apply to buried or submerged elements of the buildings or structures. NOTE: Annex A gives guidance on the principles of cathodic protection and its application to steel in concrete.

Cathodic protection of steel in concrete

ASTM C1452-00(2006) 增强的热压处理过的加气混凝土构件的标准规范

1.1 This specification covers load-bearing and nonload-bearing reinforced autoclaved aerated concrete (AAC) floor, roof, wall, and stair elements used as components for building construction. Autoclaved aerated concrete is a cementitous product based on calcium silicate hydrates in which low density is attained by the inclusion of an agent resulting in macroscopic voids and is subjected to high-pressure steam curing. Installed units covered by this specification shall be protected against direct exposure to moisture using a coating material accepted by the AAC manufacturer.1.2 The raw materials used in the production of autoclaved aerated concrete are portland cement, quartz sand, water, lime, gypsum or anhydrite, and an agent resulting in macroscopic voids. The quartz sand used as a raw material may be replaced by a siliceous fine aggregate other than sand and usually is ground to a fine powder before use. Fly ash may be used as a sand replacement. The batched raw materials are mixed together to form a slurry. The slurry is cast into steel molds. Due to the chemical reactions that take place within the slurry, the volume expands. After setting, and before hardening, the mass is machine cut with high accuracy into elements of various sizes. The elements then are steam-cured under pressure in autoclaves where the matrix is transformed into a solid calcium silicate hydrate.Note 1LOI up to 12 % may be acceptable for production of AAC provided supporting test data is presented by the manufacturer.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.

Lightweight aggregates for structural concrete

DIN EN 1740:1998 主要是纵向负载作用下(垂直构件)蒸气淬火气孔混凝土制或堆放空隙轻型混凝土制预制加强件支承性能测定

The document specifies a method of determining the mechanical performances of prefabricated components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure under longitudinal load which may be combined with transverse load. These performance include the deflection and maximum crack width in the sereviceability limit state, the loadbearing capacity (failure load) and the load-deflection diagramm, if required. The component is simly supported at its ends in vertical position and loaded until collapse by a vertical line load with required eccentricity with respect to the plane of component, in order to determine the deflection and cracking behaviour and the loadbearing capacity.#,,#

DIN EN 1742:1998 蒸气淬火气孔混凝土制或堆放空隙轻型混凝土制多层构件层间抗剪应力测定

The document specifies a method of determining the shear strength between the different layers of prefabricated multilayer components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure. The shear strength between different layers of a multilayer component is determined by applying a horizontal compression force acting in the longitudinal direction of the component at one end face on the bottom layer, while the component is resting in horizontal position on two roller supports near its ends and is supportet at the opposite end at the top layer against horizontal displacement and uplifting. The shear strength is calculated from the resulting shear force acting in the plane of the component at fracture by dividing it by the measured length and width of component.#,,#

DIN EN 1737:1998 蒸气淬火气孔混凝土或孔隙轻型混凝土预制件钢筋混凝土垫或加固篮焊接结点断裂剪切力测定

The document specifies a method of determining the shear strength of welded joints in reinforcements intended for use in prefabricated components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure. The shear strength of welded joints is determined on test specimens consisting of a longitudinal bar and a welded cross bar (transverse bar or diagonal bar) by applying a tensile force on the free end of the longitudinal bar while the welded cross bar is supportet by a device designed to minimize influence from bending and twisting forces. When joints with a diagonal bar are tested, the tensile force is applied to the free end of the diagonal bar. The tensile force is increased at uniform rate until failure of the weld, and the ultimate force is recorded.

DIN EN 1738:1998 蒸气淬火气孔混凝土制非承重加强部件钢应力测定

The document specifies a method of determining the steel stresses in longitudinal bars at midspan of unloaded reinforced components made of autoclaved aerated concrete. At midspan of an unloaded reinforced component the concrete cover, the corrosion protective coating and part of the sourrounding AAC are removed from at least three longitudinal bars, taking care to disturb the internal stresses as little as possible. Then strain gauges are glued to the surface of the bars. The steel stress is calculated from the difference of the strain gauge readings taken a) when the bar is under stress while still being embedded in the component and b) when the bar is free from external stresses after it has been separated from the component.

Autoclaved lightweight aerated concrete panels

DIN 4166:1997 加气混凝土厚板和平板

The documents contains the amendments to the december 1986 edition of DIN 4166 laid down in DIN 4166/A2(1994.02) e.g. consideration of additional dimensions for autoclaved aerated concrete slabs and panels, inclusion of further classes for dry density," new designation symbols for the slabs and panels due to changing the term ""Gasbeton"" to ""Porenbeton"""," the possibility of placing marking on a manufacturer's note included in the packaging. Clause ""Control"" has been revised and adopted to the guidelines of the new building regulations of the L刵der. The third party control given in the standard has been deleted because under public law only a declaration of conformity by the manufacturer is required as attestation of conformity for building products according to this standard.#",,#
