    • Assessing the quality of concrete – reinforcement interface in Self Compacting Concrete 

      Kanellopoulos, Antonios; Savva, Pericles; Petrou, Michael F.; Ioannou, Ioannis; Pantazopoulou, Stavroula (2020-04-20)
      Research has shown that even self-compacting concrete (SCC) mixtures can exhibit the so-called “top-bar effect” which impacts bond and anchorage. Several instances of conflicting results have nevertheless been published ...

    • By-product materials in the production of next generation SCC 

      Kanellopoulos, A. D.; Mathaiou, M.; Petrou, Michael F.; Ioannou, Ioannis; Neophytou, M. (CRC Press/Balkema, 2008)
      Self-Compacting Concrete (SCC) is an advanced type of concrete that can flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. In hardened ...

    • Dauerhaftigkeitsindikatoren für SVB entwicklung einer leistungsorientierten bemessung der dauerhaftigkeit von SVB 

      Kanellopoulos, Antonios; Ioannou, Ioannis; Petrou, Michael F. (2010)
      The fundamental principle behind the development of SCC has been the nanoscale tailoring of cementitious matrices. Although self-compacting concrete (SCC) is currently used in many countries, there is a fundamental lack ...

    • Durability of similar self-compacting concrete batches produced in two different EU laboratories 

      Sfikas, Ioannis P.; Kanellopoulos, Antonis; Trezos, Konstantinos G.; Petrou, Michael F. (2013)
      The present study intends to evaluate the sensitivity of self-compacting concrete (SCC) mixtures, cast in two different laboratories of the European Union, with a focus on rheological parameters, mechanical characteristics ...

    • Durability performance of self-compacting concrete 

      Kanellopoulos, Antonios; Petrou, Michael F.; Ioannou, Ioannis (2012-12)
      Although self compacting concrete (SCC) is currently used in many countries, there is a fundamental lack of the intrinsic durability of the material itself. This article presents the outcomes from a research program on ...

    • Mechanical and durability properties of concretes containing recycled lime powder and recycled aggregates 

      Kanellopoulos, Antonios; Nicolaides, Demetrios; Petrou, Michael F. (2014-02-28)
      According to a recent report by the European Commission, within the European Union, the construction and demolition wastes come to at least 450 million tons per year. Roughly 75% of the waste is disposed to landfill, despite ...

    • Reproducibility of self-compacting concrete batches between two different EU laboratories 

      Sfikas, Ioannis P.; Kanellopoulos, Antonis; Trezos, Konstantinos G.; Petrou, Michael F. (2012)
      Self Compacting Concrete (SCC) offers a wide variety of advantages during casting. Considering the worldwide uniformity of guidelines concerning the composition and casting instructions for the production of fresh SCC, ...

    • Self-consolidating concrete and its bond to reinforcement 

      Kanellopoulos, Antonios; Petrou, Michael F.; Ioannou, Ioannis (Precast Prestressed Concrete Institute, 2010)
      Research has shown that high slump concrete mixtures can exhibit bond problems especially at the top-cast bars due to blocking of bleed water underneath the reinforcement. As far as self-consolidating concrete is concerned ...

    • Static response and modelling of impact resistance of UHPFRCC slab specimens 

      Nicolaides, Demetris; Lampropoulos, Andreas; Kanellopoulos, Antonios; Savva, Pericles; Mina, Anna; Petrou, Michael F. (lsraeli Association of Construction and lnfrastructure Engineers (IACIE) and Faculty of Civil and Environmental Engineering, Technion - lsrael lnstitute of Technology, 2013)
      The demand for improved properties of the construction materials increase with time and the related design and construction codes are adapted in an analogous manner. UHPFRCCs represent a class of cement composites which ...

    • Static response of UHPFRCC slab specimens 

      Nicolaides, Demetris; Savva, Pericles; Kanellopoulos, Antonios; Petrou, Michael F. (2012)
      The aim of this study is to present the results of an extended work on the development of an Ultra High Performance Fibre Reinforced Cementitious Composite (UHPFRC) and the experimental determination of the mechanical ...

    • Towards more sustainable and environmentally-friendly concretes : The use of silica fume 

      Kanellopoulos, A.; Ioannou, Ioannis; Petrou, Michael F. (WITPress, 2009)
      Concrete is the most widely used construction material. At the same time, however, the concrete industry is a major CO2 emitter thus contributing towards global warming. While enhanced efficiency in the production of ...
