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 Foμndation (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 bricksand 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.
摘要翻译：该专利涉及一种可以通过当代建筑砖标准的耐久（即，抗冻融）非玻璃化（非燃烧）飞灰砌块（砖块，砖瓦，其他建筑产品）的方法。由美国材料试验协会（ASTM）建立。相比之下，制造非玻璃化飞灰砌块单元的现有方法不能使产品耐用 - 通过ASTM要求的50个冻融循环。通过使用本发明规定的方法，飞灰可以制成耐用的砖和其他产品，而不必在高温下加热窑中的绿色产品，从而降低与普通粘土砖相关的能量消耗和成本。该过程是由国家科学技术基金会（NSF）发起的小型企业创新研究（SBIR）项目产生的，该项目表明，通过使用这一过程可以生产耐用，非玻璃化的飞灰砌块装置。由于飞灰是燃煤发电厂大量生产的材料，从目前来看（2006年），美国产生的飞灰中只有三分之一以上被使用，其余的则作为固体废物处理，因此使用粉煤灰制砖等建筑产品不仅具有商业价值，而且有助于减少和回收燃煤电厂产生的废物。此外，今后使用这种非玻璃化（非烧制）飞灰产品会减少使用燃烧的粘土产品，这些产品需要使用化石燃料来加热窑炉中的单元，从而产生空气污染和二氧化碳，从而导致温室效应和全球变暖。因此，使用这里发明的飞灰砖具有环保的减少空气污染和全球变暖的附加优点。
