Effect of Carbonation on Microstructure Evolution of Alkali-Activated Slag Pastes Xiaoying Xie1,a, Hao Wei1,b, Xiaobao Zuo1,c, Dong Cui1,d*, 1Department of Civil Engineering, School of Science, Nanjing University of Science and Technology, Nanjing 210094, China axxy970224@163.com, bwh97923@163.com, cxbzuo1968@163.com, dcuidong@njust.edu.cn Keywords: alkali-activated slag; carbonation; microstructure; phase composition; porosity Abstract: In order to reveal the carbonation mechanism of alkali-activated concrete, the accelerated carbonation tests based on alkali-activated slag pastes were carried out.
Therefore, exploring the influence mechanism of carbonation on the microstructure of alkali-activated concrete, serves as basis for evaluating and optimizing the properties of alkali-activated concrete; better yet, such work can help promote the use of alkali-activated materials in construction engineering.
The above research is helpful to reveal the mechanism of durability degradation of alkali-activated slag concrete, and the work is also beneficial for the popularization and application of alkali-activated materials in construction engineering. 2.

Study of subway construction management mode Lixin Li1,a, Jieguan Zhang2,b and Yibo Zhang3,c 1.2.3School of Civil Engineering, Shenyang Jianzhu University, Shenyang, Liaoning, 110168, China.
By the owners and project management agreed upon services[1], the depth of cooperation division, there are project management services (PMS) mode, the Project Management Contractor (PMC) mode, Construction Engineering Management (CM) mode, the Management Contractor (MC) mode and project control (PC) mode, replacement contract mode Partnering model and so on.
This mode is based on operational and investment, construction of phase separation of thinking, it is most obvious with the features in the construction management and operations management to introduce a competition mechanism, a certain extent to achieve a market-oriented metro engineering project management of, there are beneficial to professional management.
And the urban rail transport market has become more mature, multi-structure of investment financing function can achieve better its ability to respond to network a tremendous funding gap is clearly more than a single investment structure, better meeting the needs of urban development on the metro engineering building needs. 3.2.2 Organization management structure change In the singlet phase, integrated structure to avoid the result in a substantial increase in the post-operating costs due to poor project early management, effective coordination and resolve interface issues (such as the management interface, engineering, technical interfaces, etc.). " Four separate " structure was also professional, social production can effectively reduce production costs, can also be applied to single-line stage.
