What is calcareous?

What Does calcareous Mean

Calcareous , which comes from the Latin calcarius , is an adjective used to describe what has lime . Called lime , meanwhile, the alkaline substance that is composed of calcium oxide ( CaO ).

The whitish lime is quenched or hydrates when it comes into contact with water, giving off heat. If lime is mixed with sand, it gives rise to mortar or mortar .
Returning to the idea of calcareous, the concept refers to what contains lime or specifically calcium carbonate ( CaCO3 ). Calcareous, therefore, is limestone .
When a material has a high percentage of calcium carbonate, it is called calcareous. A shell or a soil can be calcareous, to mention two possibilities.

A calcareous soil is made up of at least 15% calcium carbonate. These soils develop in the arid regions of our planet .
If the calcareous soil has the appropriate levels of nutrients and water, its productive potential is high. It is important to mention that calcium saturation contributes to maintaining the appropriate physical conditions of the soil.
A chalky mosaic , on the other hand, is produced with dyes, sand, and cement. In general, these mosaics, which are quite porous, are manufactured in a measure of 20 x 20 cm , with a thickness of 2 cm .
The tufa , finally, is a sedimentary rock . This means that it is formed when sediments accumulate, which go through different chemical and physical processes until they are consolidated. In the specific case of calcareous tuff, it is created when calcium carbonate that is dissolved in water precipitates.
