Fly ash brick.
- It is a building material, specifically masonry units, containing class C or class F fly ash and water.
- Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 °C steam bath, then toughened with an air entrainment agent, the bricks last for more than 100 freeze-thaw cycles.
- Owing to the high concentration of calcium oxide in class C fly ash, the brick is described as "self-cementing".
- The manufacturing method saves energy, reduces mercury pollution, and costs 20% less than traditional clay brick manufacturing.
- The unit price is on the order of 1000 bricks. The price will change on order of lesser or more quantity.
