A method of manufacturing a cementitious composite includes: (1) forming mixing an extrudable cementitious composition by first forming a fibrous mixture comprising fibers, water and a rheology modifying agent and then adding hydraulic cement; (2) extruding the extrudable cementitious composition into a green extrudate, wherein the green extrudate is characterized by being form-stable and retaining substantially a predefined cross-sectional shape; (3) removing a portion of the water by evaporation to reduce density and increase porosity; and (4) causing or allowing the hydraulic cement to hydrate to form the cementitious composite. Such a process yields a cementitious composite that is suitable for use as a wood substitute. The wood-like building products can be sawed, nailed and screwed like ordinary wood.
