Limestone can be processed into many various forms such as brick, cement, powdered/crushed, or as a filler. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving. Ancient American sculptors valued limestone because it was easy to work and good for fine detail.

Flux Stone: Crushed limestone is used in smelting and other metal refining processes. In the heat of smelting, limestone combines with impurities and can be removed from the process as slag. Portland Cement: Limestone is heated in a kiln with shale, sand, and other materials and ground to a powder that will harden after being mixed with water.

Portland-limestone cement (PLC) has comparable performance properties to ordinary portland cement but improves the environmental performance of concrete. PLC has been used in the United States on a limited scale in accordance with ASTM C1157 for several years, but it is still considered a relatively new technology.

Limestone Quarries. Limestone is the chief ingredient in powdered cement. Limestone in most all regions is quarried rock. In brief, Limestone is drilled, blasted and loaded into Haul trucks. From there it travels to a Crushing Unit. Sometimes there is a combination of Primary and Secondary Crushers used to reduce the limestone to a usable size.

For example, the carbonation resistance of concrete with a cement with only 15 mass % limestone was equal to that of a cement with 30 or even 50 mass % limestone when the w/c ratio was reduced from 0.5 to 0.35 or 0.3 (Figure 3). Of course, sophisticated process measures in cement plants are necessary for the production of high-limestone cements.

Bricklayer Joseph Aspdin of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove. With this crude method, he laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine it will pass through a sieve capable of holding water.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate

Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements

Portland Limestone Cement is a blended cement with a higher limestone content. Per ASTM specifications, PLCs are specified as a Type IL cement with a specified limestone replacement limit of 15%. PLC results in a product that works the same, measures the same, and performs the same as the typical Portland Cement that has been in use for decades, but with the reduced carbon footprint of cement.
