Abstract
A structural building element in the form of a panel, block 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.
Claims26
A building element comprising:
- (a) a continuous phase of cementitious material including:
- 1. a matrix having a first density, and
- 2. at least one zone dispersed within the matrix having a second density lower than the first density, wherein said continuous phase of cementitious material extends throughout said matrix and said lower density zone;
- and wherein
- (b) the matrix includes a first wall section and a generally parallel and opposing second wall section, said first wall section having at least one first lateral section extending away therefrom at least half the distance between said first and second wall sections but terminating short of said opposing second wall section at a lower density zone disposed between the terminal end of the lateral section and the second wall section, and said second wall section having at least one second lateral section, spaced longitudinally from said first lateral section, extending away therefrom at least half the distance between said first and second wall sections but terminating short of said opposing first wall section at a lower density zone disposed between the terminal end of the lateral section and the first wall section.

A wall assembly comprising a plurality of longitudinally abutting building elements, wherein each building element comprises:
- (a) a continuous phase of cementitious material including:
- 1. a matrix having a first density, and
- 2. at least one zone dispersed within the matrix having a second density lower than the first density, wherein said continuous phase of cementitious material extends throughout said matrix and said lower density zone;
- and wherein
- (b) the matrix includes a first wall section and a generally parallel and opposing second wall section, said first wall section having at least one first lateral section extending away therefrom at least half the distance between said first and second wall sections but terminating short of said opposing second wall section at a lower density zone disposed between the terminal end of the lateral section and the second wall section, and said second wall section having at least one second lateral section, spaced longitudinally from said first lateral section, extending away therefrom at least half the distance between said first and second wall sections but terminating short of said opposing first wall section at a lower density zone disposed between the terminal end of the lateral section and the first wall section.
