Limestone - Missouri Department of Natural Resources
Main Uses of Limestone: 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.
