摘要：
Microtomographic (mu CT) and thin section (TS) images were analyzed and compared regarding porosity and its distribution along the samples. The results show that mu CT although limited by its resolution, shows relevant information about the distribution of porosity and quantification of connected and non-connected pores. TS have no limitations concerning resolution, but are limited by the experimental data and can only give information about connected pores. These two methods have their own advantages but when paired together they are able to make for a more complete analysis. (C) 2014 Elsevier Ltd. All rights reserved.
