Abstract: The fundamental principle behind the development of SCC has been the nanoscale tailoring of cementitious matrices. The introduction of fillers with small particle size made possible the better packing of particles within the cementitious matrix whereas at the same time the incorporation of superplasticizers into the mix, significantly improved the flowability of the material. Although self compacting concrete (SCC) is currently used in many countries, there is a fundamental lack of the intrinsic durability of the material itself.
The scope of the current study is to present the outcomes from a research study on some principal indicators that define the durability of SCC and how these are compared with the corresponding parameters of conventional concrete. More specifically the porosity, the capillary absorption, the water permeability are obtained and compared for both SCC and conventional concrete. Furthermore, it will be investigated how the addition of industrial byproducts(fly-ash, lime powder that comes from the production of asphalt concrete, microsilica) affects the durability parameters of SCC.
