From the aspect of the development of science and technology, it represents the production technology level of a specific historical stage in the process of social development, and reflects the application of scientific and technological achievements to practical production.
No matter the application of new building materials in the construction of factory buildings, the practice of the new construction technology, or the new development of natural science and technology reflected through the mechanical, chemical or materials technology during the production, they all show science and technology level of Tianjin in the past
(3) Beneficial to Achieve Low-carbon Economy and Ecological Environmental Protection A building will consume large amounts of energy and emissions of carbon dioxide and other pollutants from the production materials to the construction, so it always destroys the ecological environment.

Performance Evaluation of Construction Materials Management in Expressway Project CHEN Yun1, a, LI Jingjing2, b 1,2 School of Traffic & Transportation Engineering of Changsha University of Science & Technology, Changsha, Hunan Province, China, 410114 acheny1963@163.com, bljj792@126.com Keywords: Construction Materials; Performance Evaluation; Process Analysis; Expressway Abstract.
The long cycle and high cost of the expressway construction make its construction materials have very big difference with general production materials.
From above, construction materials are tangible materials that constitute the engineering entity.
According to the cost of expressway construction materials, construction materials is defined as tangible material which constitutes the engineering entity, as well as auxiliary materials of engineering entity, structural parts, components, semi-finished products, working materials, mechanical equipment and completion waste, etc.

Moreover, all materials were isolated by introducing vacuum slabs of 12.5 Å perpendicular to the tube axis.
Results and Discussion Fig.3a shows the isolated C39N-acid system and the binding mechanism between the two materials.
