Influence of PP Fibers on the Relative Residual Splitting Tensile Strength of HSC after Exposure to High Temperatures Ruizhen Yan1,a, Weihua Ge1,b and Hongxiu Du1,c,* 1College of Architecture and Civil Engineering, Taiyuan University of Technology, Shanxi, China a13834593958@163.com,bgeweihua_tyut@163.com,ctydhx@163.com Keywords: PP fiber, HSC, high temperature, relative residual splitting tensile strength Abstract: In order to discuss the effect of different cooling methods, dosage and length of PP fiber on the splitting tensile strength of PPHSC after high temperatures, experiments were carried out on the splitting tensile strength of C60 HSC mixed with PP fibers with different dosage( 1.0kg/m3, 1.5 kg/m3, 2.0kg/m3, 2.5 kg/m3) and length (8mm,19mm) before and after high temperatures.
Introduction HSC has been widely used in engineering and construction with its high compressive strength, great load capacity, lower energy consumption and higher durability.

Monitoring of Reinforced Concrete Structure Corrosion by Using Impact-Echo Method Kristýna ŠAMÁRKOVÁ1, a, Daniela ŠTEFKOVÁ1,b and Zdeněk CHOBOLA1,c 1Department of Physics, Faculty of Civil Engineering, Brno University of Technology, Žižkova 17, 602 00 Brno, Czech Republic a samarkova.k@fce.vutbr.cz, b stefkova.d@fce.vutbr.cz, cchobola.z@fce.vutbr.cz Keywords: Frequency inspection, Impact-Echo method, acoustic method, corrosion, reinforced concrete, Thomson double bridge.
The frequency inspection (Impact-Echo method) belongs to the family of non-destructive testing methods and can be applied in many branches, among others also in civil engineering [6, 7].
An MIDI piezoelectric sensor was used to pick up the response, the respective impulses being fed into the input of an oscilloscope TiePie engineering Handyscope HS3 two-channel with resolution 16 bits.
