ABSTRACT
Whereas permeability tends to be often controlled by pore connectivity, the elastic properties and strength of concrete are affected by the total volume of pores, in particular, the distribution of macropores which are sized greater than 50 nm (Marsh et al., 1985, Bamforth, 1987). However, for Geopolymer (GP) concrete, the pore connectivity, permeability and the resulting equivalent transport properties responsible for degradation mechanisms are yet to be fully characterized (Criado et al., (2003), Xu & van Deventer, 2000, Steveson, et al., (2005)). This paper therefore examines aspects of the inter-relationships between strength and permeability to address fundamental parameters likely to contribute to long-term GP concrete performance.
