If consider the energy consumption in the production process of building materials, the proportion will be 46.7% [1].
At the architecture design stage, the evaluation about consciousness on building materials selection mainly involves the building materials’ physical performance, sources and emissions of greenhouse gas.
Such as the heat transfer characteristics of building materials, sealing properties, strength properties and durability properties.
Assessment should advocate use local materials or nearby materials, reduce transportation cost and greenhouse gas emissions in the process of transportation.
The assessment of the Construction materials mainly involves the impact of building materials and construction method on the environment, for instance, the frequency of welding used.

Metal oxides nanoparitcles are used for CO gas detecting [3], promising materials for gas detecting are semiconductor metal sulfides such as CuS [4], AgS [5], WS2 [6] MoS2 [7] and other.
Production method for these materials is exfoliation of WS2/MoS2 crystal and following deposition on Si/SiO2 substrates.
Metal dichalcogenides particles produced from metal nanopowders and characterized by nanoscale layers [11] are promising materials for multipurpose application including gas sensor.

Preparation of Al2O3-SiC Composite Powder by Carbothermal Reduction of Coal Gangue and its Influence on Properties of Blast Furnace Stemming Qi Wanga, Lina Zhangb, Xin Minc, Minghao Fangd*, Xiaowen Wue, Yangai Liuf, and Zhaohui Huang1g 1Beijing Key Laboratory of Materials Utilization of Nonmetallic Minerals and Solid Wastes, National Laboratory of Mineral Materials, School of Materials Science and Technology, China University of Geosciences (Beijing), Beijing 100083, P.R.
But its main raw materials are high-quality oxide materials and synthetic raw materials, so the cost is very high.
It’s a new method of alleviating China's high-quality raw materials consumption and the utilization of solid waste minerals[6].
According to the proportion, weighing coal gangue 50g and carbonaceous materials 27.07g into Teflon ball milling tank, with agate ball milling as grinding medium, blending 12h, the raw materials were fully mixed.
According to tab 1 raw materials were accurately weighed and mixed into a collergang after adding tar.
