Mechanical behavior of the cement mortar with high amount of Municipal Solid Waste Incineration (MSWI) bottom ash as an alternative aggregate Kirill Polozhiy1, 2, a *, Martin Keppert1, b, Marcel Jogl3, c, Robert Černý1, d 1 Department of Materials Engineering and Chemistry, Faculty of Civil Engineering, Czech Technical University in Prague, Thákurova 7, 166 29 Praha 6, Czech Republic 2University Centre for Energy Efficient Buildings, Czech Technical University in Prague, Třinecká 1024, 273 43 Buštěhrad, Czech Republic 3 Experimental Center, Faculty of Civil Engineering, Czech Technical University in Prague, Thákurova 7, 166 29 Praha 6, Czech Republic akirill.polozhiy@fsv.cvut.cz, bmartin.keppert@fsv.cvut.cz, cmarcel.jogl@fsv.cvut.cz, dcernyr@fsv.cvut.cz Keywords: Municipal Solid Waste Incineration, bottom ash, cement mortar, mechanical properties Abstract The aim of this study was to find out an application of the municipal waste incineration materials and try to use them
So it has become an attractive material for application in civil engineering industry, because using of the waste products leads to the cost reduction.
But still resulting material is acceptable for application in civil engineering industry, because of the ratio of bulk density/compressive strength.

Introduction Externally bonded carbon fiber method, FRP (fiber reinforced materials) applied in civil engineering has always been a hot focus in recent years.
CFRP is the earliest fibers material with most mature technology, and is also one high-tech fibers material used in civil engineering with the largest amount so far.

A New Distribution and Application in Engineering Reliability Zhangmiao Li 1,a , Fenghua Jiao 2, Xinjian Kou 1, Yanmeng Zhang1 1School of Naval Architecture, Ocean and Civil Engineering, Shanghai Jiao Tong University, No. 800 Dongchuan Road, Shanghai, China 2China Construction Industrial Equipment Installation CO.
Failure probability of a component is the major project of engineering probability.
For this reason, normal distribution is modified as it is generally used in investigation of engineering reliability theory [3,4,5,6] and in mechanic engineering[7,8].
The breadth of intercepted interval (fromto) is determined by actual engineering.
