Limestone: who, what, when, why & how
Effectiveness depends on the purity of the material and how finely it is ground. Pure limestone has a calcium carbonate equivalence (CCE), or neutralizing value, of 100 percent. All other materials are compared with this standard. The CCE of commercial limestone products should be available through the vendor.

As it moves through the layers of limestone, the water dissolves calcium carbonate on the ground and under the ground, and in that way, sinkholes or caves are formed. Regions built of limestone are called karst regions and have karst topography because the active process of dissolving limestone causes the appearance of sinkholes and ...
