feb 11, 2021 limestone has two origins: biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and mechanical transport and deposition of preexisting limestones, forming clastic deposits. travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. limestone has long fascinated earth scientists because of its rich fossil unlike limestone, it has a looser, earthy structure; therefore, it refers to specifically designed raw materials for wet production. chalk is soft raw material, it does not require crushing. marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.it is a transitional stage to clay.
hydrated lime is essential to the production of sugar from both sugar cane and sugar beets. It is also used to purify sugar derived from other sources, such as maple or sorghum. sugar cane and sugar beets are harvested and processed with water to form raw juice, limestone is so favorable material that in case of any damage, the tile can be changed very quickly. the tile replacement is not a big issue. color matching is widely available in the market. you just have to get a new piece and fit in the place of broken tile. when compared with other types of tiles in the market, the price of limestone tiles
