ESTIMATING OF THE DURABILITY AND WEATHERING STATE OF ROCK MATERIALS USING CHEMICAL WEATHERING INDICES BASED ON CATION PACKING VALUE: A CASE STUDY
Abstract
Weathearability and/or the performance of the building stones in service are depend heavily on mineralogical composition, fabric, especially micro-fissure properties, and weathering state of rocks material. When cons idering the definition of the k-value, it is possible to say that the k-value can be used for characterizing the weathering state and weatherability of a rock. As decomposition of a mineral result in the formation of new minerals with lower k- value, the k-value of whole rocks is generally regarded as a measure of the degree of weathering. The difference between the k-value of fresh sample and the k-value of weathered sample gives the amount of chemi cal leaching. k- leaching index exhibits good correlations with both micro-fissure plus voids and the weathering indices representing chemical leaching. The difference between the k-value of the whole sample and the k-value of the unaltered parts of the same samples gives the amount to weathering product. Therefore the ratio of the difference to k-value of the same sample is defined as k-product index These indices are applied on the select ed weathering profiles in the Kurtun Granodiorite, NE Turkey, for the estimation of the effects of petro-chemical properties on the durability of the rock materials a nd weathering state. There are found the statically meaningful relationships between the static and dynamic durability indicators and these chemical weathering indices based on k-value. It is shown that k-leaching index and k-products index, defined in this study can be used to evaluate the chemical weatherability and weathered state of weathered rocks materials. Key words: k-value, chemical weathering indices, durability, rock durability indicator, granite, NE Turkey.
