Are You Mining Minerals for Cement, or for Concrete?

Aug 01, 2017  The concrete is the final product used in buildings, roads, infrastructure, etc. You can think of cement as the “glue” that holds the sand and gravel and re-bar (reinforcement bar) together to make concrete. Cement manufacturers mine and process raw materials

The mining of sand, a non-renewable resource - GreenFacts

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

How Concrete is Made - Portland Cement Association

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

There were some pits that had steel headgear that was over 100 years old, so says a lot for steel. As long as it's painted to protect it from corrosion, I'd say it would outlast concrete by many years.
