    • The cement type effect on freeze – thaw and deicing salt resistance of concrete 

      Skripkiūnas, Gintautas; Nagrockienė, Džigita; Girskas, Giedrius; Vaičienė, Marija; Baranauskaitė, Erika (Procedia Engineering, 2013)
      This paper analyzes the effect of the four types of cement (Portland cement, blast-furnace Portland cement, limestone Portland cement and blast-furnace cement) on freeze-thaw and deicing salt resistance of concrete. Eight ...

    • Chemical technologies for modern concrete production 

      Yaphary, Yohannes L.; Lam, Raymond H. W.; Lau, Denvid (Procedia Engineering, 2017)
      Modern era is linked with global issues in limited energy resources and ecological degradation as hurdles for sustainable industrialization and urbanization. In these contexts, concretes are the most widely adopted ...

    • Fatigue life comparison of recycled cold mixes with foamed bitumen and with bitumen emulsion 

      Buczyński, Przemysław; Iwański, Marek (Procedia Engineering, 2017)
      The paper presents the results from the fatigue tests of recycled bases containing foamed bitumen and bitumen emulsion. The amount of bitumen used in both cases was 3% and 5%. For the production of the bitumen emulsion ...

    • Fired hydraulic binder based on fluidized combustion fly ash 

      Gazdič, Dominik; Kulísek, Karel; Fridrichová, Marcela; Dvořák, Karel (Procedia Engineering, 2017)
      This study is focused on possibilities of utilization of fluidized combustion fly ash for manufacturing of fired hydraulic binders as one of the principal raw materials for production of binders close to traditional ...

    • Freeze - thaw resistance and increased strength of cohesive soils modified with a cationic surfactant 

      Błaszczyński, Tomasz; Babiak, Michał; Kosno, Jacek; Węgliński, Szymon (Procedia Engineering, 2017)
      The problem of adequate load carrying capacity of the base coarse layer of road surfaces or load-bearing layer of industrial floors or building foundations arises during the realization of every investment undertaking. The ...

    • Influence of emergency braking on changes of the axle load of vehicles transporting solid bulk substrates 

      Vrabel, Jan; Jagelcak, Juraj; Zamecnik, Jan; Caban, Jacek (Procedia Engineering, 2017)
      When flowable solid bulk commodities are transported, their distribution in a vehicle cargo space may change due to a dynamic load, mainly due to intensive braking. This cargo movement causes changes of a load of particular ...

    • Influence of silicon carbide and electrocorundum on the thermal resistance of cement binders with granulated blast-furnace slag 

      Kantel, Teresa; Ślosarczyk, Agnieszka (Procedia Engineering, 2017)
      The aim of this work was to compare the influence of the electrocorundum and silicon carbide on the strength and the microstructure of the cement composite with the addition of granulated blast-furnace slag, before and ...

    • Physical properties and structure of composite made by using hemp hurds and different binding materials 

      Balčiūnas, Giedrius; Vėjelis, Sigitas; Vaitkus, Saulius; Kairytė, Agnė (Procedia Engineering, 2013)
      Maximum power consumption comes to building heating, which depends on the efficiency of building envelopes. Energy consumption of building sector covers 50% of the total energy consumption. Reducing building energy cost ...
