How can you tell limestone from concrete? You can tell limestone from concrete by their appearance and texture. Cement, which is used to make concrete, is typically gray, white, or off-white in color and has a fine, powdery texture. Limestone, on the other hand, comes in a range of colors, including white, beige, yellow, and gray, and …
The more complicated the limestone structure, the more sampling and testing required to ensure the delivery of quality limestone to the process. In these conditions, the number of core holes will have to increase to define the areas of quality limestone and the geologic structures, and to determine the "mineability" of the deposit.
Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded.
