Abstract
A structural building element in the form of a panel or related configuration having a continuous phase of cementitious material which includes an interconnected matrix having a first density and a plurality of zones dispersed within the matrix, wherein the zones have a second density lower than the first density. Reinforcement members may be embedded within portions of the interconnected matrix to impart additional strength to the element.
Claims22
A building element having a high structural load bearing capacity and comprising:
- a. a continuous phase of cementitious material, wherein said continuous phase includes:
- b. an interconnected matrix in the form of a cellular structure and having a first density, and
- c. a plurality of zones dispersed within the matrix having a second density lower than the first density, wherein the matrix comprises a plurality of wall sections substantially completely surrounding the lower density zones with at least one portion of the matrix disposed interiorly of the element between said low density zones for interconnecting opposed wall sections of the matrix, and
- d. a common cementitious bond between the wall sections of the matrix, the interiorly disposed interconnecting portion of the matrix, and the lower density zones for producing a synergistic relationship imparting increased compressive strength and minimization of fracture propagation throughout the element.
