SBIR Phase II: Compacting Fly Ash to Make Bricks

小企业创新研究（SBIR）第2期项目的目的是进行利用燃煤发电厂产生的副产品或废弃物粉煤灰制砖的新技术商业化所需的研究开发。 在第一阶段进行的研究表明，已知的粉煤灰砖的冻融问题可以通过空气夹带来解决。 与传统工艺相比，该工艺在室温下将大量废料转化为有用的产品，成本低，空气污染小，节省能源。第二阶段的工作将测试第一阶段未测试的粉煤灰砖的关键性能，研究改变砖的颜色和形状的方法，并研究扩大工艺规模的关键步骤。

This Small Business Innovation Research (SBIR) Phase II project has the objective of conducting R&D needed for commercialization of new technology to make bricks using fly ash, which is a byproduct or waste material generated at coal-fired power plants. Research conducted under Phase I demonstrated that the known freeze/thaw problem of fly ash bricks can be solved using air entrainment. This process converts a high volume waste material into a useful product using a room temperature process, with cost, air pollution nd energy savings, compared to traditional processes.The Phase II work will test key fly ash brick properties not tested in Phase I, investigate ways to vary the brick's color and shape, and study key steps in scaling up the process.
