Forced carbonation of recycled concrete aggregates
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The production of concrete, especially the contained cement clinker, causes a high proportion of the manmade gaseous air pollution. Studies show that the decarbonation of limestone effects roughly 8% of worldwide CO2 ... -
Fracture behavior of multiple adhesive postinstalled anchors subjected to shear force
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In this study, experiments were conducted on post-installed anchors subjected to shear force in order to enhance applicability when post-installed anchors were used for seismic reinforcement. Furthermore, since there were ... -

Full probabilistic design of a submerged floating tunnel and format for partial safety factors
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)A submerged floating tunnel (SFT) can be a promising solution for crossing a deep or wide waterway. This innovative concept however lacks research into its probabilistic design. In this research, the reliability of the ... -
Fundamental properties and durability of slope protection spray mortar reinforced with bamboo fibers
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In order to enhance resistance against cracking and durability, short fibers such as steel and organic fibers have been conventionally mixed into spray mortar used for slope protection. In this research, fundamental ... -
Generation of mesostructure for lattice discrete particle model
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)A preliminary study of two approaches for the internal structure generation utilized in the lattice discrete particle models (LDPM) [1] is presented. The presented methods used for particle generation and placement are ... -
Glued timber concrete composite walls using ultra-high-performance concrete
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This paper gives a short introduction of the development of cross laminated timber (CLT) concrete composite walls with a glued connection. In the composite walls, prefabricated ultra-high-performance concrete (UHPC) lamellas ... -
Heat transfer model verification for thermal monitoring system of integral bridges
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Thermal actions considered on abutments of integral bridges by the European standard (Eurocode 1) might be in variety of certain situations underestimated. Based on this assumption, thermal monitoring system has been ... -
High thermal conductivity concrete for energy piles
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Research is increasingly focusing on thermal properties of concrete with the aim of reducing the heat exchange between buildings and environment. On the other hand, concretes with high thermal conductivity could have ... -
High-performance concrete containing waste vitrified tiles
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This contribution deals with the possibility to use waste vitrified tiles (VT) in high-performance concrete.
