The objective of this study is to examine the effects of the geological properties of limestone on the synthetic characteristics of precipitated calcium carbonate (PCC) and hydraulic activity. Four groups of limestone samples from eight different limestone deposits according to formation age have been studied. With greater formation age of limestone such as samples from the Paleozoic Ordovician (500~430 million years ago), more calcite twins were presented. Whereas the newest limestone from the Cenozoic Tertiary (65~2 million years ago) had no calcite twins. Furthermore, hydraulic activity and the production yield of aragonite-shaped PCC increased with lower formation age of limestone.
