Title: Chloride Diffusivity of GGFBS Concretes
Author(s): K. Ganesh Babu and V. Sree Rama Kumar
Publication: Special Publication
Appears on pages(s): 611-622
Keywords: chloride diffusivity; concrete; GGBS; mixture design; per-centage
Abstract:The paper presents the results of the chloride diffusivity of a wide spectrum of concretes with compressive strengths ranging from 30 - 120MPa having GGBS incorporation ranging from 0 - 85%. All these concretes were designed to have specific compressive strengths at the various percentages of replacement through an efficiency concept presented earlier. The chloride diffusivity of these concretes was assessed in accordance with the method suggested by ASTM C 1202 after 90 days of water curing. Tt was observed that a significant improvement in the chloride diffusivity could be achieved even in the lower strength concretes at the higher replacement levels. This clearly shows that it is not always necessary to have high strength to achieve the high chloride impermeability performance in concrete.
