    摘要: This patent deals with a method to make durable (i.e., freeze/thaw resistant), non-vitrified (non-fired) fly ash masonry units (bricks, blocks, tiles and other construction products), that can pass contemporary standards for building bricks established by the American Society for Testing and Materials (ASTM). In contrast, existing processes for making non-vitrified fly ash masonry units cannot make products durable—passing the 50 freeze/thaw cycles required by ASTM. 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. The process resulted from a Small Business Innovation Research (SBIR) project sponsored by the National Science Foundation (NSF), which demonstrated that durable, non-vitrified, fly ash masonry units can be produced by using this process. Since fly ash is a material generated in large quantity at coal-fired power plants and since currently (in 2006) only about a third of the fly ash generated in the United States is used with the rest being disposed of as solid waste, use of fly ash to make bricks and other construction products not only has commercial value but also helps to reduce and to recycle wastes 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. Therefore, use of the fly ash brick invented here has the additional advantage of being environmentally friendly—reducing air pollution and global warming.

    摘要: A method for making aggregate includes the following steps: (a) preparing a wet mixture by mixing water with a combination of ingredients in a mixer, the combination of ingredients including by weight about, 68% to 95% fly-ash and 2% to 10% lime; (b) dropping the wet mixture into at least one pile on a base surface; (c) allowing the wet mixture in the pile to substantially completely hydrolyze into a hard product; and (d) crushing the product to form the aggregate. Preferably, step (b) further includes forming an arcuate stack having multiple overlapping conical piles of the dropped wet mixture such that the stack extends a circular distance over the surface. The wet mixture may be transported from the mixer to a height above the surface and dropped to the surface by a radial stacker. The combination of ingredients, preferably, further includes by weight 0.5% to 12% alkali hydroxide and, more particularly, sodium hydroxide.
