MEASUREMENT of the primary porosity of massive limestone gives little indication of the rate of underground movement, which takes place largely along joints and bedding planes. There is also the ...

To make concrete, limestone, or calcium carbonate, is mixed with clay and other materials and then calcined at high temperatures, so CO2 is released via the thermal decomposition of calcium carbonate.
