A hinge (11) for use in hydraulically settable materials is provided. The hinge (11) has a hydraulically settable matrix (10) formed from a reaction product of a hydraulically settable binder and water, with fibrous material dispersed in the matrix. Additional components may be utilized in the matrix (10), such as rheology-modifying agents, aggregate materials and substances to produce air voids. The hinge (11) of the invention allows hydraulically settable materials to be bent along a line without breakage of the material. The hinge (11) is particularly useful in cementitious containers that require bending of various container parts, such as in food containers and boxes made from cementitious materials. |
