Modification of cement concretes by addition of the polymer latex, in order to obtain composites with improved engineering properties.
Herein，we reported a kind of polymer-cement waterproof coating with a relatively low polymer-cement ratio (P/C=0.12), in the case that the composites was conformed to the request of Ⅲ-type polymer water proof coating in Chinese standard GB/T23445-2009. Ⅲ-type waterproof coating is most widely used for civil buildings.
Conclusion As one of the most widely material for civil building, Polymer-cement waterproof coating is applied in the toilet, kitchen and roof in common.

In this context, the Gafsa Phosphate Company initiated a project to build sludge retention dikes using quarry waste to store phosphogypsum, with potential applications in civil engineering.

Calculation and Analysis Techniques of Foundation Pit Engineering Based on FLAC3D Yuliang Qiu1,2, Xiaoyong Hu2, Zhu Wang2, and Mingyi Zhou2 1 School of Civil Engineering, Beijing Jiaotong University, Beijing, 100044, China 2 CCCC First Highway Consultants Co., LTD Xi’an, 710075, China vetec@163.com, hu_i@sohu.com, cwz123456789@sohu.com, 284933558@qq.com Keywords: Excavation, FLAC3D, Three-dimensional stratigraphic model, Numerical analysis, Design.
At present, the mainstream pit analysis software is based on elastic method, and the applied effect is good in practical engineering [1].
This research can provide the basis for both design and research work in foundation pit engineering. 2 Two-Dimensional Load Structural Calculation Mode FLAC3D software, offering a variety of constitutive models to suit different materials and plentiful structure elements, can easily simulate the soil-structure interaction, including dynamic, static, flow, thermal, creep calculation model and multimode coupling analysis, has become an important analysis method for geotechnical engineering numerical works.
Mohr-Coulomb model and Modified Cam-Clay model are commonly used in elastic-plastic geotechnical engineering numerical calculation.

Mechanical Properties and Design Consideration of Skewed Simple Supported Bridge Ning Wang, Bing Wu Airport College, Civil Aviation University of China, Tianjin 300300, China E-Mail: nwang@cauc.edu.cn Keywords: Skewed bridge; Finite element analysis; Time history analysis; Bearing Abstract: Due to the special geometry at the ends, skewed bridges are different from squared bridges.
Skewed bridges are more common in highway engineering than square bridges because skewed bridges can adapt to more various requirement, in such cases when the center line of overpass is not perpendicular to the highway underneath, and when the pier has to be skewed to the crossing river to decrease the impact of water flow.
And in the design, engineers try to be conservative, which leads to much waste of material.
