As one important treatment approach of modern engineering, the grouting technology is applied in many engineering fields such as to civil engineering, hydraulic engineering, municipal engineering, and mining.
For grouting of the underground engineering, the selection of the grouting materials is particularly important [4].
There are several kinds of classification for the grouting materials in the engineering practice.
Therefore, the low-cost grouting materials which meet the above requirement have been a development goal pursued by the engineering field [3].
Considering the large scale application in engineering, both economy and toxicity of the grouting materials should be considered.

Establish a reasonable safeguard measures is one of the key factors for the successful training of the "outstanding engineers" in new colleges and universities.

Discussion on the Sound Radiation Coefficient of Building Materials Yan Yang a, Xianfeng Huang b and Jun Liu c Key Laboratory of Disaster Prevention and Structural Safety at Guangxi University, Ministry of Education & College of Civil Engineering and Architecture, Guangxi University, Nanning 530004, China a774969688@qq.com, bseulee@163.com,c294746901@qq.com Keywords: sound radiation coefficient, building material, sound insulation Abstract.
Due to influence of radiation on the sound transmission in a structure, sound radiation coefficient plays a significant role on the option of sound insulation materials during the practical engineer.
The Radiation Efficiency of Different Building Materials Some common building materials are used to calculate the radiation efficiency with 1/3 octave band center frequency.
The critical frequency of the same materials decreases with the thickness of a wall.

Introduction Recently, substantial research efforts have been made in the field of engineering and design of materials, material structures and innovative treatments for human protection.
Therefore, the engineering challenge is to produce protective materials, material structures and clothing systems with adequate protection against the relevant hazard whilst achieving thermal comfort for the wearer [6, 7] or, in other words, to attain the best balance between the physiological burden and protection for optimal performance.
The primary direction of current materials engineering is in materials and structures of reduced weight that offer comparable or superior protective attributes.
The present research demonstrated an innovative holistic approach to engineering and evaluation of new protective materials and garments through a combination of objective laboratory testing, multi-compartmental mathematical modeling and 3D body imaging and design.

Hydrophobic expanded perlite used in external insulation of the building engineering Jie Zhang 1, Yun Xue2 The school of architecture & civil engineering, Inner Mongolia University of science and technology, Baotou, Inner Mongolia, 014010, China 1zhangjieav@163.com,2 xueyun062_cn@163.com Keywords: Expanded perlite; Water absorption; Freeze-thaw resistance performance; Hydrophobic perlite products; Building insulation materials Abstract.
Expanded perlite products with hydrophobic technology, the advantages of both ordinary expansion perlite products, but also solve the problem of absorbent easy and freeze-thaw resistance poor, as the application of external insulation materials in building engineering has been expanded.
Since the hydrophobic expanded perlite products not only has the ordinary expanded perlite products light, non-toxic, good insulation properties, refractory corrosion resistance advantages, but also solve the easy to absorb water, freeze-thaw resistance difference problem, make it as the application of external insulation materials in building engineering has been expanded .
In order to ensure the quality and durability of external thermal insulation engineering, insulation board should adopt full bonding method, and the bond strength conforms to the requirements of the relevant standard. [6] [7] To prevent the plaster layer cracking feed water is one of the key technologies to ensure the quality of external thermal insulation engineering.
As long as the materials used qualified, reasonable structural measures, construction specifications, we can improve the quality of external thermal insulation engineering.
