Abstract

A wall may be formed by a method comprising providing an extrusion platform having a plurality of perforations extending through a surface of the extrusion platform, and extruding a cementitious composite through the perforations of the extrusion platform to grow a plurality of cementitious composite rods each extending from a respective one of the perforations. The method may further comprise allowing the cementitious composite rods to cure to provide the wall.

First claim

What is claimed is:

1. A method of forming a wall, comprising:
providing an extrusion platform having a surface with a plurality of perforations extending therethrough;
extruding a cementitious composite through the perforations of the extrusion platform to grow a plurality of cementitious composite rods extending from the extrusion platform by at least placing the extrusion platform at a desired wall height above a support structure with the perforations facing downward and toward the support structure, and causing a downward growth of the cementitious composite rods from the extrusion platform to the support structure, the perforations of the extrusion platform molding a cross-sectional shape of the cementitious composite rods; and
allowing the cementitious composite rods to cure to provide the wall.

2. The method of claim 1 , further comprising leaving the extrusion platform in place as a header for the wall after allowing the cementitious composite rods to cure.

3. The method of claim 1 , wherein the cementitious composite comprises a hybrid polymer and cement composite.

4. The method of claim 1 , wherein the cementitious composite comprises a macro-defect free cement.
