Introduction With the advantages of high rigidity, effectively subjecting to vertical and horizontal loads and small deformation, shear wall structures have been widely used in high-rise civil building and the large industrial buildings through the development of new technology such as sliding template and big template.
To the test concrete strength grade, C40 has been taken to the model structure, for the prototype structure’s practical situation and the civil concrete strength grade’s tendency to high strength.

Application of High Ti-bearing Blast Furnace Slag in Field of Building Materials Li-Xia HE School of Civil Engineering and Architecture, Panzhihua University, Sichuan, China 915103348@qq.com Keywords: High Ti-bearing Blast Furnace Slag, Building Materials, Application, Environmental Protection.
The crushed BF slags can be used as concrete aggregate equivalent to the ordinary gravels, and mainly used for the concrete with design strength of C50 or below, reinforced concrete and prestressed concrete of general industrial and civil buildings and structures.
It is applicable to the wall and foundation of industrial and civil buildings.
Application of High Ti-bearing BF Slag in Pavement In the late 1970s and early 1980s, when the high titanium crushed slag concrete was used for industries and civil buildings, the crushed slag concrete and the cement-stabilized slags were used in low-traffic road works.

Study and application on the kinetic parameters of elastic wave for the engineering rockmass Hong Yi Wang1, a, Wu Xiu Ding1, b, Tao Xu2, c 1Luoyang Institute of Science and Technology, Luoyang, Henan 471023, China 2School of Civil Engineering, Henan Polytechnic University, Jiaozuo, Henan 454000, China aWHylswl@163.com, bwuxiu-ding@163.com, cxutao.0420@163.com Keywords: Elastic wave, Wave velocity, Attenuation coefficient, Dominating vibration frequency, Engineering rockmass.
Therefore, if the measured elastic wave velocity is directly applied to the quality assessment of engineering rockmass, it will not can reflect the actual engineering properties of the rockmass.
So the velocity values measured in the different directions are always different for the same engineering rockmass, and even have a big difference, which result in the difficulty to apply the wave velocity to reflect really the engineering properties of the rockmass.
Therefore, the value of the measured frequency can be used to research the engineering properties of the rockmass.
Due to the anisotropy characteristics of the rockmass, for the engineering rockmass of layer structure, and will be obviously different and can not be applied directly to appraise the engineering rockmass.
