Description :
The aim of this research is to investigate, using a laboratory simulation approach, whether increasing levels of CO2 in rainfall would contribute towards increased dissolution of limestone, particularly of previously exposed surfaces (weathered limestone) that may have inherited a greater susceptibility to dissolution. The rate and nature of dissolution were investigated through : 1) weight loss of samples, 2) change in water chemistry of solutions and 3) detailed SEM observations of surface change, particularly the presence of dissolution features. 28 samples cut from a block of Bath (Box Hill) limestone from Somerville College, Oxford were analysed.
