    • APPLICABILITY OF CARBON FIBRES IN REFRACTORY CEMENT COMPOSITES 

      Autor: Holčapek , Ondřej; Reiterman , Pavel; Konvalinka , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The main objective of this article is to present the influence of high temperatures on mechanical properties of advanced refractory cement composite reinforced with carbon fibres. The presented material is suitable for ...

    • AUTOGENOUS SHRINKAGE OF COMPOSITES BASED ON PORTLAND CEMENT 

      Autor: Davidová, Vendula; Reiterman, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Autogenous shrinkage of cement based composites is important property influencing number of their engineering application. Its ultimate value is predominantly determined by mineralogical composition of cement and its ...

    • CYCLIC TEMPERATURE LOADING RESIDUAL FLEXURAL STRENGHT OF REFRACTORY SLABS 

      Autor: Holčapek , Ondřej; Reiterman , Pavel; Konvalinka , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper describes the effect of cyclic elevated temperature loading on refractory slabs made from high performance, fibre reinforced cement composite. Slabs were produced from aluminous cement-based composites, reinforced ...

    • CZECH WW2 CONCRETE FORTIFICATIONS: CORROSION PROCESSES AND REMEDIATION METHOD BASED ON CRYSTALLIZING COATING 

      Autor: Pazderka, Jiří; Reiterman, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Concrete is a relatively new structural material, hence the remediation of concrete structures is very rare. There are a lot of concrete fortifications in the Czech Republic, which were built just before WW2. These bunkers ...

    • FRESH STATE PROPERTIES OF LIME MORTARS WITH FLAX OIL ADMIXTURE 

      Autor: Bauerová, Pavla; Reiterman, Pavel; Pavlíková, Milena; Kracík Štorkánová, Magdalena; Keppert, Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Flax oil has been used as mortar improving, hydrophobic, admixture already in ancient times. The paper describes the identification of flax oil in mosaic mortar from ca. 1900 by help of FTIR spectroscopy. This historic ...

    • INFLUENCE OF AGGRESSIVE ENVIRONMENT ON THE TENSILE PROPERTIES OF TEXTILE REINFORCED CONCRETE 

      Autor: Machovec , Jan; Reiterman , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      This article deals with the long-term durability of a relatively new composite – textile reinforced concrete (TRC). The studied composite material introduces a modern and favourite solution in contemporary architecture and ...

    • OPTIMIZATION OF MIX-DESIGN OF CHEMICALLY RESISTANT SPRAYED CONCRETE 

      Autor: Hermann, Radek; Drochytka, Rostislav; Kolísko, Jiří; Reiterman, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      This paper addresses optimization of mix-design and granulometric curves of aggregate of chemically resistant cementitious sprayed mix. The target of the paper is to improve properties of currently developed mix-design, ...

    • SHRINKAGE OF VARIOUS TYPES OF PORTLAND CLINKER-BASED CEMENTS WITH RESPECT TO THEIR HYDRATION DEGREE 

      Autor: Davidová , Vendula; Reiterman , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The volume changes of cement based composites are significantly exhibited in the hardening process. Initial phases of the hardening are complemented by the expansion due to the heat evolution that is subsequently alternated ...

    • SIZE EFFECT ON THE ULTIMATE DRYING SHRINKAGE OF CEMENT MORTAR: 1-YEAR EXPERIMENT AND NUMERICAL MODELING 

      Autor: Dohnalová, Lenka; Havlásek, Petr; Šmilauer, Vít; Reiterman, Pavel; Davidová, Vendula
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The magnitude and time evolution of shrinkage are influenced by numerous factors which are implemented in the design codes often in a different way. The time-dependent behavior of concrete in structures sensitive to creep ...
