Hygric Transport Parameters of Several Kinds of Sandstones Dana Koňákováa, Monika Čáchováb, Martin Keppertc, Eva Vejmelkovád, Robert Černýe Department of Materials Engineering and Chemistry, Czech Technical University in Prague - Faculty of Civil Engineering, Thákurova 7, 166 29 Praha 6, Czech Republic adana.konakova@fsv.cvut.cz,bmonika.cachova@fsv.cvut.cz, c martin.keppert@fsv.cvut.cz, deva.vejmelkova@fsv.cvut.cz, ecernyr@fsv.cvut.cz Keywords: Sandstone; Open porosity; Pore size distribution; Water vapour diffusion resistance factor; Water absorption coefficient Abstract.
Therefore sandstones still belong to important civil engineering materials.
The most common used sandstones in civil engineering branch are the quartozse one, so mainly quartzose sandstones were chosen for a need of this study.
A chemical and a structural diversity is the reason why sandstones have so different properties.The most used sandstones in a civil engineering branch arequartzose sandstones, since they have appropriate physical properties as for example great mechanical characteristics.
They are the most used kind of sandstones in civil engineering branch, since they have the best properties.

Reasonable Elevation Calculation of Temporary Pier of Long-span Steel Trussed Arch Bridges with Semi-cantilever LUO Xu1, a, CAI Lurong2, b 1School of Civil Engineering and Transportation, South China University of Technology, Guangzhou 510640, China; 2School of Civil Engineering and Transportation, South China University of Technology, Guangzhou 510640, China; a 4929746@qq.com, bcailurong304@163.com Keywords: Steel truss girder; semi-cantilever; temporary pier; elevation Abstract.
So, systematically study of reasonable setting of temporary pier elevation has important engineering significance.
In practical engineering computations, due to the complexity of the structure, the construction process and completed bridge calculation by using finite element software MIDAS or ANSYS is often able to obtain more accurate results.
By using the finite element software MIDAS/CIVIL, it can be easy to simulate bridge construction process.
