<p>This patent deals with a method to make durable, non-vitrified fly ash masonry bricks, blocks, tiles and other construction products. By using the process specified in this invention, fly ash can be made into durable bricks and other products without having to heat the green products in kilns at high temperature, thereby reducing energy consumption and costs associated with making ordinary clay bricks. Fly ash, which is typically disposed of as solid waste, is used in the method to make bricks and other construction products, and thus reduces waste generated at coal-fired power plants. Furthermore, use of such non-vitrified (non-fired) fly ash products in the future reduces the use of fired clay products, which require using fossil fuel to heat the units in kilns, which in turn generates air pollution and carbon dioxide that causes greenhouse effect and global warming.</p> |
