Abstract
The alteration of rocks intended for use as the foundations of large-scale civil-engineering projects, for building construction and for rock piling has been studied and numerous tests carried out; some of these tests have been standardized in varying degrees. The conventional method of autoradiography has been used to develop one of the processes for estimating alteration due, in particular, to thermal shocks. By using {sup 35}S and {sup 32}P, the authors were able to follow the progressive alteration of different rocks in the form of microfissurations. This process is considerably more accurate than that based solely on utilization of the characteristics of rocks in normal or polarized light. In addition, it permits absolute comparison of the initial microfissuration conditions of the sample and the microfissuration found after an increasing number of thermal shock cycles. The results of the process are given in the paper.
