Crushed Limestone Rock vs. Crushed Concrete Rock
As a result of the number of questions that we at Select Sand & Gravel receive regarding the usage of Crushed Limestone Rock versus Crushed Concrete Rock, we felt it was important to state the differences in these types of Rock. There is an abundance of both materials in Dallas, Fort Worth, Austin, San Antonio, and Houston Texas markets that our company serves. We thought it would be useful to write an article to provide an overview as to the pros and cons of each type: Crushed Limestone Rock and Crushed Concrete Rock. Both of these Aggregate Rock materials are used in the formulation of concrete as well as other applications. As such, a quick explanation of concrete would also be of assistance.
Concrete was originally formulated by the ancient Romans. Generally speaking, it is poured into a mold when in the liquid form. Over the course of time it hardens into a formidable surface. Concrete is a mixture of cement, sand, and crushed rock or stone of different varieties. In the Texas area most of the crushed rock that is utilized is crushed limestone, crushed concrete, or a smooth river rock. The hardness of the stone is very important as there is a correlation between stone hardness and strength of the finished concrete.
There are other uses for Crushed Limestone. Specifically, this type of rock can be used as:
Road Base
Construction Entrance Rock
Pipe Embedment (Pipe Bedding)
Rip Rap (Erosion Control)
Under a construction slab
Driveway Gravel
Roofing Gravel surface
