Abstract

The results are reported of 4 experimental weathering tests - freeze - thaw, wetting and drying, slake durability and salt weathering - on 5 different types of limestone. Effective porosity, mercury intrusion porosimetry and scanning electron microscopy were used to evaluate changes in pore properties, while weight loss and fracture density were used to assess deterioration severity. A primary aim was to observe modifications in porosity due to weathering and to draw inferences about the internal rock deterioration mechanisms taking place. It is concluded that the 5 limestones not only show a wide range of resistance to weathering in general but considerable difference in resistance to particular weathering processes
