    • Alkali-silica reactivity of Portland-composite cements and gravel aggregates 

      Žvironaitė, Jadvyga; Pranckevičienė, Jolanta; Kligys, Modestas; Balčiūnas, Giedrius; Macanovskis, Arturs (Ceramics-Silikáty, 2019)
      The potential alkali-silica reactivity (ASR) of various combinations of Portland-composite cements CEM II/A, and Lithuanian aggregates from three gravel deposits are investigated in this work. These aggregates which contain ...

    • Composite fibers in concretes with various strengths 

      Macanovskis, Arturs; Lukasenoks, Arturs; Krasnikovs, Andrejs; Stonys, Rimvydas; Lusis, Vitalijs (ACI materials journal, 2018)
      Concrete beams reinforced by short composite macrofibers uniformly distributed in their volume were tested mechanically in bending. The short composite macrofibers were a few centimeters long and less than 2.5 mm (0.01 ...

    • Effect of short fibers orientation on mechanical properties of composite material – fiber reinforced concrete 

      Lusis, Vitalijs; Krasnikovs, Andrejs; Kononova, Olga; Lapsa, Videvuds-Arijs; Stonys, Rimvydas; Macanovskis, Arturs; Lukasenoks, Arturs (Journal of civil engineering and management, 2017)
      Traditional fiberconcrete structures have fibres in the mix oriented in all spatial directions, distributed in the structural element volume homogenously, what not easy to obtain in practice. In many situations, structurally ...

    • Experimental investigation and modelling of the layered concrete with different concentration of short fibers in the layers 

      Boris, Renata; Kononova, Olga; Macanovskis, Arturs; Stonys, Rimvydas; Lasenko, Inga; Krasnikovs, Andrejs (Fibers: Special issue: Mechanics of fiber reinforced cementitious composites, 2021)
      The use of steel fiber reinforced concrete (SFRC) in structures with high physical-mechanical characteristics allows engineers to reduce the weight and costs of the structures, to simplify the technology of their production, ...

    • Mechanical behavior of polymeric synthetic fiber in the concrete 

      Macanovskis, Arturs; Krasnikovs, Andrejs; Kononova, Olga; Lukasenoks, Arturs (Procedia Engineering, 2017)
      Results of damage and failure investigation in a concrete reinforced by short polymeric fibers are reported in the present work. Two types of fibers were used in experiments 30mm and 6mm long. Pull-out experiments were ...
