Alternative Material: AshCrete - RTF Rethinking The Future

A Detour into Fly Ash. Fly ash is the main component of Ashcrete. It is used to replace cement in the concrete mixture due to its natural pozzolanic properties. This means that, like volcanic ash, fly ash reacts with calcium hydroxide in the presence of water to produce a strong, sturdy material that is stronger than regular cement.
