This code was formulated by China Northeast Architecture Design and Research Institute Co.,Ltd.and Guangsha Construction Group Co.,Ltd.as well as the organizations concerned according to the requirements of Document JIANBIAO ［2006］ NO.77 issued by the former Ministry of Construction (MOC)-Notice on Printing the Development and Revision Plan(the First Lot)of National Engineering Construction Standards and Codes in2006.

During the process of formulating this code,the code drafting group carried out a large number of investigations on the current state of wall materials used in the engineering in China and necessary experimental verifications with regard to certain subjects and conducted extensive researches and discussions with the wall material manufacturer,engineering design,construction,supervision and quality control organizations as well as the relevant management departments,based on which,it provided the new practices and achievements of the wall material innovation and building application in recent years;through full consideration of the development and application state of wall materials in China carried out the technology integration with view to meeting the requirements of wall material quality and building engineering application,discussed,modified and supplemented the code repeatedly by extensively asking for opinions and suggestions from the organizations and experts concerned,and finalized this code finally upon review.

This code mainly covers:general provisions,terms and symbols,wall materials,architectural design and architectural energy saving design,structure design,crack control for wall and construction requirements,construction,acceptance,wall maintenance and test.

Provisions printed in bold type in this code are compulsory and must be enforced strictly.

The Ministry of Housing and Urban-Rural Development is in charge of the administration of this code and the explanation of the compulsory provisions;China Northeast Architecture Design and Research Institute Co.,Ltd.is responsible for the explanation of specific contents.During the process of implementing this code,all relevant organizations are kindly requested to put forward and send the opinions and suggestions,on the basis of combining the practical engineering application of wall materials and carefully summarizing the experience,to the Administrative Group of China Northeast Architecture Design and Research Institute Co.,Ltd.for reference to later revise theUniform Technical Code for Wall Materials Used in Buildings(Address:No.65,Guangrong Street,Heping District,110003,Shenyang City,China;Email:gaoly@masonry.cn).

List of Quoted Standards

3.1.4 The non-autoclaved silicate brick(block)and non-autoclaved aerated concrete product shallnot be adopted for the wall.

3.1.5 The moisture absorption&efflorescence test, warping deformation test and water resistancetest shall be carried out for the magnesium oxycholride wall product.When their test indexes meet the service requirements, same group of product shall be applied in the engineering.

3.4.1 Freeze-thaw test shall be carried out for the mortar when the wall is designed to resist damageof frost thawing.The freeze-thaw cycles shall be the same as that of the wall masonry unit..

4.1.8 The vegetable fiber wall materials containing asbestos fiber and those without corrosion-resistant and mothproof treatment shall not be adopted.

5.4.2 The wind-resistant design shall be carried out for the sandwich insulation composite wall.

5.4.3 The connection design shall be carried out to resit wind for the external wallboard.The plateand the major structure shall be connected flexibly.

5.5.2 The design safety grade of the load-bearing capacity of the connector between the externalwallboard and the major structure shall be increased by one grade.

6.1.9 When the non-thin plaster is selected for finish coat of outer-insulation the composite wall,the construction measures against self-weight deformationshall be taken.

6.1.10 Crack control measures shall be taken for the connecting parts between the inner-insulationcomposite wall and the beam/column.
