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 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 ... -
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 ... -
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 ...
