    Abstract: Embodiments of the present disclosure are directed to a low density monolithic fiber cement article that incorporates controlled air entrainment evenly distributed throughout the article to improve various physical properties of the article. In some implementations, air entrainment agents are used to create voids in the article, thereby lowering the density and weight of the boards while maintaining adequate strength. In some implementations, the air entrainment agents can be added in solution to create a foam, or can be used to generate a pre-foam, which can be added to a cementitious paste. The cementitious paste incorporating the air entrainment agent can proceed through an extrusion process, experiencing high pressures, where the voids remain in the final monolithic fiber cement board.

    Abstract translation: 本公开的实施方案涉及低密度整体纤维水泥制品,其包含均匀分布在整个制品中的受控空气夹带以改善制品的各种物理性质。 在一些实施方案中,使用空气夹带剂在制品中产生空隙,从而降低板的密度和重量,同时保持足够的强度。 在一些实施方案中,可以将溶剂中的空气夹带剂加入到产生泡沫中,或者可以用于产生可以添加到水泥糊中的预泡沫。 掺入空气夹带剂的水泥糊可以经历挤压过程,经历高压,其中空隙保留在最后的整体式纤维水泥板中。
