摘要： It has been unexpectedly discovered that the addition of a natural or other pozzolan to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. The natural pozzolan may be a volcanic ejecta, such as pumice or perlite. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts.

摘要翻译： 已经意外地发现，将非规格飞灰添加到天然或其它火山灰中可显着改善非规格飞灰的性能，使其可以根据ASTM C618和AASHTO 295认证，作为F级 或C级飞灰。 天然火山灰可能是火山喷发，如浮石或珍珠岩。 其他火山灰也可用于该选矿过程。 许多火山灰经过实验测试，可用于将非规格飞灰精选成可证明的F级飞灰。 此外，本公开提供了将C类飞灰转化为更有价值的F级飞灰的方法。 这一发现将扩大F级飞灰供应的减少，并将非规格飞灰废物流转化为有价值的，经过认证的飞灰火山灰，这将保护和增强混凝土，砂浆和灌浆。

摘要： It has been unexpectedly discovered that the addition of ground-granulated blast-furnace slag to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts.

摘要： It has been unexpectedly discovered that the addition of a non-spec natural pozzolan to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash, by utilizing natural pozzolans. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts.
