摘要： A method for producing lightweight concrete is disclosed which comprises mixing foamed particles, aggregates, and cement slurry to create a strong, lightweight concrete. The foamed particles can be created by grinding foamed plastic waste material. The aggregates comprise soluble glass, water, and polyvinyl acetate. One embodiment includes batching the cement in two stages. The concrete is pressed to within 65-70% of its volume prior to drying. Lightweight concrete comprising foamed plastic particles mixed with cement, water, soluble glass, and polyvinyl acetate is also disclosed, where the concrete, after compacting and drying possesses greater strength than common polystyrofoam concrete.

摘要： The invention disclosed is a self-supporting porous ceramic material, which is typically used in ceramic filters as a substrate prior to coating with a thin dense membrane layer of additional ceramic material. Conventional ceramic support structures are not necessarily designed as membrane support substrates. They are typically made with monosized particles and have a uniform cross section. The present support structure is made via a polydisperse slurry method where a functionally gradient structure is achieved by a colloidal destabilization technique. The key for achieving this structure is to colloidally unstable or metastable suspensions of a controlled and broad particle size distribution, so that segregation based on particle diameter will occur during consolidation. This produces a continuously finer mean particle diameter axial profile from one major surface to the other on the cross section of the consolidated structure. The particle size distribution control is achieved by blending different ceramic powders. In terms of volume fraction, the continuous particle size distribution of the powder used to make the suspension is preferably coarse-rich.
摘要翻译：所公开的发明是一种自支撑多孔陶瓷材料，其通常用于陶瓷过滤器作为基材，然后用附加陶瓷材料的薄致密膜层进行涂覆。传统的陶瓷支撑结构不一定设计为膜支撑基底。它们通常由单粒子制成并具有均匀的横截面。本发明的支撑结构通过多分散浆料法制备，其中通过胶体去稳定化技术实现功能梯度结构。实现这种结构的关键是胶体不稳定或亚稳态悬浮液的受控和宽的粒度分布，使得在固结期间将发生基于粒径的偏析。这在固结结构的横截面上产生从一个主表面到另一个主表面的连续更细的平均粒径轴向轮廓。通过混合不同的陶瓷粉末来实现粒度分布控制。在体积分数方面，用于制备悬浮液的粉末的连续粒度分布优选是粗的。
