Abstract: Fibers of diverse materials find widespread use in inorganic binder compositions to improve the properties of the final cured composite materials. When using high amounts of fiber in inorganic binder slurries, problems arise due to the loss of workability because of unevenly distributed fiber content. The fibers according to the invention allow the use of large amounts of fiber without loss of workability and are particularily useful to control the rheology of the composite slurry mixtures. The fibers according to the invention are bicomponent fibers comprising a first hydrophobic polymer and a second hydrophilic polymer, and are obtained by: - uniaxially stretching a sheet of a first polymer; - oxidizing one side of a sheet of said first polymer; - coating the oxidized side of a sheet of said first polymer with said second polymer; - drying the resulting bicomponent substrate; - cutting the dried bicomponent substrate into fibers of desired dimensions.

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.
