What advantages does the fly ash brick offer over conventional bricks?
Fly ash bricks have the following advantages: • Cost less to produce – at least 10% less than concrete bricks and 20% less than clay bricks. Details on cost will be addressed later in this document. • Save construction cost – Due to the uniform shape and size of the fly ash brick, it saves labor in laying bricks by about 15%. This translates into an estimated 7 cents reduction in labor cost in laying each brick. • Use less energy – Much energy is consumed in firing clay bricks in kilns. By using fly ash bricks instead of clay bricks, much energy is saved in brick manufacturing. Details on energy saving will be addressed later in this document. • Reduce air pollution – Much fossil fuel is used in heating clay bricks in kilns. Burning such fuel generates air pollution and greenhouse gas (CO2), contributing to global warming. By manufacturing fly ash bricks (at room temperature) instead of clay bricks (at over 2,000oF), emission of air pollutants and greenhouse gas is avoided at brick pla
