When it is used to make concrete
Concrete is not as likely to rot, corrode, or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the worksite which reduces costs. Concrete is a noncombustible material which makes it firesafe and able withstand high temperatures.

Portland Limestone Cement Lafarge Canada. Portland limestone cement contributes to lowering the industry''s carbon footprint not only during the manufacturing process. While cement typically represents only 11% of a concrete mix, it accounts for more than 80% of all energy required to produce concrete.
Apr 24, 2017 · Limestone is used in virtually all construction materials. Limestone is added in with clay and heated to form cement, which can be made into mortar by adding sand and water. Mortar is used to set bricks and act as an adhesive when it dries. Limestone is also used in concrete and asphalt filler.
Mortar stains often take the shape of drips and drabs, which are unsightly and uncomfortable to walk over. They''re a common problem after the installation of pavers and can ruin the look of your limestone. You don''t have to hire someone to get rid of them, however.

Dec 06, 2018 · After manufacture, cement undergoes a "carbonation" process wherein concrete exposed to CO2 and humidity slowly bonds with the CO2, storing the carbon in mineral form. Because concrete is porous, CO2 slowly can diffuse into concrete, carbonating the cement to a depth of 60 millimeters or more over a number of years.
