Limestone

There are several types of limestone: plain, shell and chalk. Ordinary limestone is used as a building material and for the production of lime and cement. Shell limestone is so called because it still shows the shells of various animals. It is very beautiful and is used for cladding buildings, fountains and more. The chalk is very soft (soft limestone). It is used to make chalk.

Limestone is divided into three categories depending on its density in approximate limits as follows:
– Low density – Limestone, the density of which varies from 1760 to 2160 kg./m3
– Average density – from 2160 to 2560 kg./m3
– High density – over 2560 kg / m3

Limestone contains a number of distinguishable natural characteristics, including calcite streaks or spots, fossils or shell formations, pit holes, reedy formations, open texture streaks, honeycomb formations, iron spots, travertine-like formations and grain formation changes. One or a combination of these characteristics will affect the texture.
