The studies on storage period provide supports to the using of dry-mixed shotcrete in engineering application.
Introduction Sprayed mortar was first used to the mining and civil engineering in America at 1914 and developed to shotcrete later.
As shotcrete having many advantages such as high mechanical strength, good bonding, fine durability, working in high altitude, pit, and narrow working construction, etc, shotcrete technology was widely used in mine and underground engineering of tunnel lining, geotechnical slope stability, architectural structure, bridges and tunnels of reinforcement and support, complex modelling of thin-walled structure and other engineering fields [1-5], and played an unique function and obviously benefited in recent years.

The Stability Impact Study for Blasting near Underground Caverns Chengman Sha1, a , Ende Wang1, Jianfei Fu1, Genqun Hou1, Tianbao Zhang1 1 College of Resources and Civil Engineering, Northeastern University, Shenyang 110819, Liaoning, China.
Nowadays, the safety effection study of the surface explosion operations on underground cavern safety become more and more important along with engineering construction's development.
Along with the development of all kinds of engineering construction, cases of safety effection study of the surface explosion operations on underground cavern safety often appear.
For geotechnical engineering materials, range of the minimum critical damping ratio is generally 2% ~ 5%[8].

Large Ranging of Ultrasonic Testing Inspection Internal Defects of Mass Concrete Structure Lin Liu1, 2, a, Wen Zhao1,b 1 College of Resource and Civil Engineering, Northeastern University, Shenyang 110000, China 2 Subway research institute, Shenyang jianzhu university, Shenyang110000, China aliumumu118@163.com, bwenneu@163.com Keywords: ultrasonic testing; large ranging; sound velocity Abstract.
The ranging greater than 3m is not accorded with china engineering construction standardization association standard “TECHNOLOGICAL SPECIFICATION FOR INSPECTION OF CONCRETE DEFECTS BY ULTRASONIC METHOD”[CECS 21:2000] (Transducer spacing is 2~3m).
The engineering examples of on the electric power tower foundation by UT method The electric power tower was in winter operation in Hebei province.
Conclusion In summary, by analyzing an engineering example, we discussed when testing distance increase to 5.1m, the data is valid, and analyzes the relationship between the sound velocity and distance.

Determination Method of Critical Path in Fuzzy Network Planning Based on Improved Lattice Close-degree Theory LI Wanqing1, a, CHEN Mujie1, b, MENG Wenqing2, c and MA Lihua1, d 1 College of Economics and Management, Hebei University of Engineering, Handan, Hebei, China; 2College of Civil Engineering, Hebei University of Engineering, Handan, Hebei, China a mujie-chen@163.com, b chenmujie88@163.com, chelili0910@163.com, d408238600@qq.com Keywords: Fuzzy network planning; Completion period; Critical path; - cut set; Lattice close-degree Abstract.
But in modern complex systems of engineering construction, it is very difficult to determine the critical path in network planning for it has fuzzy characteristics, the traditional CPM and PERT method couldn’t accurately describe the behavior and characteristics of such systems, therefore, it is required to introduce fuzzy set theory to study these problems [4, 5].
