This paper concerns some issues that were difficult application for the practical engineering or had potential to be improved.
Therefore, the replacement of hook by T-head as the end anchor can avoid the above problems so as to improve engineering application with good quality.

Experimental Investigation on Properties of High Performance Concrete with Mineral Admixtures in Pavement of Highway Le-Hua Yua, Shuang-Xi Zhoub and Hui Ouc Department of Civil Engineering, East China Jiaotong University, Nanchang, 330013, China ayulehuanc@tom.com, bgreen.55@163.com, couhui@ecjtu.jx.cn Keywords: cement; high performance concrete; mineral admixture; ground granulated blast furnace slag; fly ash.
To meet demand of high performance pavement concrete in highway, different proportional concretes incorporating 30%—40% ground granulated blast furnace slag and (or) fly ash were investigated on engineering properties in laboratory.
Flexural strength tests are performed in accordance with Technical Specification of China Traffic Ministry JTG E30—2005 [9] (testing methods of concrete for China highway engineering).
Accordance with Technical Specification of China Traffic Ministry JTG E30—2005 [9], flexure strength of concrete is the most important technical target during design, constructure and acceptance check for highway engineering in China.

In order to achieve a life-cycle use of BIMs, it is critical that the Architecture, Engineering, Construction, and Operations (AECO) industry determine if it is moving closer to achieving a mature BIM standard or if organizationally it is still just grazing the surface of what BIM can do.
In 2009, Stanford’s Center for Integrated Facility Engineering (CIFE) developed their own VDC scorecard program which evaluates the maturity of VDC practices on individual construction projects based on their degree of innovation in areas of planning, adoption, technology and performance.
Within these organizations, the largest number of respondents (34%) indicated being in an upper management position in their respective organization or categorized themselves as project managers/project engineers (30%).

Really construction of ecology residence is a systems engineering.
floor space can be regarded to recuse the burden for the lower income in our country.In order ti avoid not only enhancing the floor space,but also has carried on the serious economic burden,reduced the life quality.Therefore,our country residential space is better to control between 60m2 and 110m2,that is more appropriate [4]. 3.2 Developing construction technology, uses suitable construction technology is the foundation of constructs ecology residence As a result of the architecture industry,that has consumption to natural resource's and pollution to the environment,has directly caused the anxious of our country natural resource and the stern of environment question,that is not enough to only control residential space for the green of economizing energy.Looked from the residential construction and the use that may regard as the tree parts,the production of building material,the residential construction and the residential use.Therefore,the real ecology residential construction is a engineer
