How limestone is formed? Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate CaCO3 found in seawater to create their shells and bones.
The water pressure compacts the sediment, creating limestone. How is limestone used? Limestone has numerous uses: as a building material, an essential component of concrete Portland cement , as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feedstock for the production of lime, as a soil conditioner, or as a popular decorative. What kind of rock is caliche?

I prefer a mix myself. It's also gets cut wet, and often times delivered to the job site still wet, so the color may change even more as it dries.
