    Abstract: Disclosed are cementitious product, as well as cementitious slurry, and method of forming the product. To reduce density in the cementitious product, foam is included in the slurry and in the method of forming the product. The slurry includes cementitious particles, water, and air bubbles such as from compressed air. Instead of using detergent chemistry at the gas/water interface of bubbles, the present invention uses a surface modifying agent for the cementitious particles in the slurry. The modified particles act to produce stable foam in the slurry. As an example mode of introduction, the surface modifier can be added (e.g., as solid or solution) directly into a bulk cementitious slurry that forms the product. As another example, the surface modifier can be added in a separate solution with water, air bubbles, and cementitious particles that serve as additive to the main cementitious slurry, where the separate solution is then added to the main cementitious slurry.

    Abstract translation: 公开了水泥质产品，以及水泥浆，以及形成产品的方法。 为了降低水泥质产物中的密度，在浆料和形成产品的方法中包括泡沫。 浆料包括水泥颗粒，水和气泡，例如压缩空气。 本发明代替在气泡的气/水界面处使用洗涤剂化学剂，而在浆料中使用表面改性剂作为水泥质颗粒。 改性颗粒用于在浆料中产生稳定的泡沫。 作为一种示例性的引入方式，可以将表面改性剂直接加入（例如，作为固体或溶液）到形成产品的块状水泥质浆料中。 作为另一个实例，表面改性剂可以与用作主要水泥浆料的添加剂的水，气泡和水泥质颗粒在单独的溶液中加入，然后将单独的溶液加入到主要水泥浆中。
