Cracking due to shrinkage and restraint can accelerate corrosion of concrete resulted from harmful environment. Sulfate resistance of concrete under restrained condition was researched during drying and wetting cycles. The results showed that restraint can lead to controlled concrete cracking as result of shrinkage. It decreased sulfate corrosion resistance of concrete compared with free concrete. Due to 30% slag and 20% fly ash was added, surface cracking was avoided but scaling mass still higher than free concrete after drying and wetting cycles.

This paper describes the development of a flexible wall permeameter apparatus for measuring the water and air coefficients of permeability of residual soils. Water and air coefficients of permeability were obtained for both the drying and wetting cycles for residual soils using the flexible wall permeameter. Volume changes of the soil specimens during unsaturated consolidation and during the water and air permeability measurements were also monitored. Factors that influence the measurements, such as hydraulic and pneumatic gradients and temperature fluctuations are described and discussed in this paper. The developed flexible wall permeameter was found to be capable of measuring water and air coefficients of permeability as low as 10–12 m/s.Key words: flexible wall permeameter, permeability, residual soils, unsaturated soils, matric suction, flow rate.
