Quality Control of Envelope Insulation Building under Construction Yun Xue1 , GuoMing Dong2,HuiXia Wen3 The school of architecture & civil engineering, Inner Mongolia University of science and technology, Baotou, Inner Mongolia, 014010, China 1xueyun062_cn@163.com, 2dongguoming0107@163.com Keywords: Building energy efficiency; Construction project; Material performance; Construction technology; Quality control Abstract.
The construction of envelope insulation building is an important part of building energy-saving engineering.
So, in order to ensure the quality of building energy-saving construction, before constructing, the construction unit should specially prepare technical scheme for building engineering construction, with agreement of special supervision engineers.
To building energy-saving projects and its quality, carefully prepared construction technical scheme of building energy engineering is very important, as well as the strict enforcement of norms. 2.
So, according to the "Rules", construction units should test sampling reinspection of materials under the witness of supervision engineers.

So engineers often encounter the following issues.
The clay minerals have a great impact on the engineering properties.
