Scale issues in the degradation of Geomaterials.
Scale issues and the crossing of scale boundaries has long been a fundamental question within geomorphological research. In particular the transference of detailed understanding and measurement of process, material and morphological interactions at the micro-scale into an explanation of how complex systems operate over larger spatial and temporal scales.
Traditionally, quantification of surface change on in-situ building blocks and laboratory based weathering experiments were small scale and relied upon mechanical techniques. These were often time-consuming, risked damaging the surface being measured, and required a statistical interpolation between a limited number of points. To overcome these difficulties requires a rapid, non-contact mechanism for monitoring surface change using a dense network of measurement points. It is in search of improvement in the speed and precision of surface analysis that this study will use two 3D laser based surface scanning systems as a means of accurately and non-destructively monitoring the progressive decay of building stone in laboratory based experiments and in the field.
The aim of this research project is to investigate the spatio-temporal distribution of weathering phenomena in limestone in the built and natural environment and in particular the spatial patterns / relationships and the identification of any scale related discontinuities.
This will be achieved by using laser-scanning technologies to capture the complete geometry of weathered surfaces over a wide range of scales from microns to decimeters.
Several geostatistical techniques will be used in this study to examine surface morphology. Specifically the topographic data will be used to generate maps of local topographic roughness, areas of material loss and surface swelling. Semivariograms will be calculated for understanding the morphological and scale dependent characteristics of the topography and fractal dimensions will be used as a tool for comparing scale-dependent topographic variability of different weathering components.
