Examples of the use of computer simulation as a tool for stone weathering research

Summary

A simple computer simulation of limestone weathering was carried out. The weathering processes simulated were: changes taking place at the stone/atmosphere interface; the motion of salts and water through the stone; and changes in weathering state as a result of the previous mechanisms. Through use of the simulation, three issues in weathering research are addressed: evidence is provided for the passivation of limestone surfaces by gypsum; insights into the so-called "memory effect" are presented; and the pitfalls involved in rapid cycle laboratory experiments are illustrated.  18 refs.
