Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is the revision of JG 3063-1999 "industrial ash concrete hollow wall slats," compared with the main technical changes JG 3063 as follows.

--- Added terms, technical indicators, test methods and other content;

--- Increase the "solid slats" and "partition wall, wall panels," the content;

--- Added "softening coefficient", "heat transfer coefficient", "freeze-thaw," "anti-infiltration", "node connection capacity"

--- Modify the scope of products including light concrete slab;

--- Modify the scope of the application of lightweight concrete slab;

--- Modify the physical and mechanical properties of "area density", "sound insulation sound insulation weight", "bending damage load" index;

--- Modify the "moisture content", "hanging force", "fire resistance limit", "compressive strength", "drying shrinkage value" indicator;

--- Modify the product factory inspection of the provisions of the project;

--- Removed the specification size "100mm thick plate", an increase of "120mm, 150mm, 180mm thick plate";

--- Remove the size deviation in the "tongue, and groove, tenon" control indicators, an increase of "wall thickness" control indicators.

1 Scope

This standard specifies the terms of concrete lightweight slat products, classification and marking, general requirements,, test methods, inspection rules, standard Log, transport and storage.

This standard applies to precast concrete lightweight slats, including industrial ash concrete slats, natural light aggregate concrete slats, artificial light set Concrete slab.

Concrete lightweight slats for non-load-bearing partition wall for general civil and industrial buildings can be used for non-load-bearing outer wall of low-rise buildings.
