 · Combining this cement with water and aggregates (such as sand, gravel, and crushed stone) creates concrete. CO2 gas can be turned into a solid aggregate for concrete; this can be done with only minimal external energy—which is one reason why CO2 use in concrete has the largest potential in the short term. CO2 can also be used to cure concrete. For this .

The simple formula shown above illustrates the method of checking moisture content of sand, gravel, crushed rock, and /or fresh concrete.
