In the early 21st century, the amount in Japan had exceeded 80%.In the nineties of last century, water-reducing agents that applied in the engineering were mainly naphthalene, melamine and other traditional water-reducing agent.
However, the most of the application of the water-reducing agent could not meet the requirement of the engineering.
Therefore, the main purpose of this study is to promote and improve the overall level of this research and the level of application in practical engineering.

Experimental Study on Improving Frost Resistance of CA Mortar Likun Wang1,a*, Lihua Zhao2,b, Jisong Zhang3,c 1,2,3School of Civil Engineering, Dalian Jiaotong University, Dalian, 116028,China al1996k10@163.com, bZhaolihua1015@126.com, c13516000013@163.com Keywords: Cement asphalt mortar; Orthogonal experimental design; Air-entraining agent; Mechanical properties; Frost resistance.
For CA mortar serving in severe cold areas, good frost resistance is one of the key engineering problems that need to be solved urgently.
Therefore, in practical engineering, the dosage of cement, emulsified asphalt and sand can be adjusted according to the above dosage range, and the CA mortar meeting the requirements can be obtained.
In practical engineering, mixing speed and mixing time have different degrees of influence on the working and mechanical properties of CA mortar.

Drying Shrinkage and Prediction Model of Alkali-slag Concrete Yawei Fu, Liangcai Cai, Yonggen Wu (School of Civil Engineering, Xi’an University of Architecture and Technology, Xi’an 710055, Shanxi, China; fuyawei06@163.com) Key words:alkali-slag concrete; drying shrinkage; prediction model; workability; strength Abstract: Green high performance alkali-slag concrete(ASC) was prepared by adding Na2SiO3 and NaOH complex activator in slag.
Drying shrinkage make against concrete structure, are prone to crack, affect the bearing capacity of concrete structure, debase the anti-penetrability, imperil the durability and safety of concrete structure enormously, so academe and engineers have beening attach importance to it.
