Soil moisture is critical to the reaction of limestone, therefore rainfall patterns in the area should be used as a guide. Coarse limestone reacts more slowly and, as will all limestones, is most effective when incorporated into the soil. When a more rapid and longer lasting pH adjustment is needed, the use of finely ground limestone is available.
Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. The calcium carbonate content of limestone rocks has been used from the earliest civilisations, dating back to 14,000 BCE, to its extensive use in modern times.
In this research we report the result of a study carried out to identify rocks that might be used for the production of dimension stone based on knowledge of the …

The limestone was provided for this work by OMYA ® (Nièvre, France), containing > 97% of calcite (Calcium carbonate CaCO 3). The kaolinite used was supplied by Proclay ® (Beaujard site—Poigny, France); this clay is constituted of quartz and kaolinite. The F1lab. is a premix reconstituted in the laboratory with 80% limestone and 20% kaolinite.
Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations. Type of Limestone
