Abstract

quest to reduce cement content in concrete. One material that has been used in concrete in some parts of the world for many years, but is receiving renewed interest globally, is limestone powder [ 18], typically available in the form of the calcite polymorph of calcium carbonate and with varying percentages of magnesium (carbonate).

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Cement is the most widely used material in existence and is only behind water as ...

Missouri Limestone - Missouri Department of Natural Resources

In Missouri, limestone of all kinds is used mainly for aggregate (aka “gravel”) that is produced by crushing and screen-sizing limestone quarry rock. The aggregate is used in concrete, for road surfacing (with or without asphalt or tar binder), and for foundation support beneath weight-bearing structures.
