What naturally occurring stone is the bedrock for all concrete products?
Answer Limestone
Going all the way back to 1300 B.C.E., limestone has been the fundamental ingredient in concrete. It was then that people discovered the strength of limestone, especially when ground down and mixed with sand and water. This mixture is cement, and cement is the foundation of concrete.
