Abstract
This invention provides improved strength structural building elements having improved insulation properties. The element comprises a monolithic form with at least a pair of opposed faces and at least one aperture which extends between the opposed faces. In one embodiment, the building element is formed of a mixture of expanded cellular synthetic material, sand of a particular finus modulus to impart improved strength, and cementitious material with the cellular material being distributed throughout the structural element. In another embodiment, the building element is formed of expanded cellular material of three approximately equal particle size distribution ranges to provide expanded strength characteristics, sand and cementitious material. Both embodiments can be dry cast.

In a structural building element having improved strength characteristic formed of cementitious material, sand, cellular synthetic material and filler material, the improvement comprising
- a structural element of a monolithic form having at least a pair of opposed faces and at least one aperture extending between said opposed faces, said cellular material being distributed throughout said element, and being composed of small discrete particles in which there are a plurality of particle size distribution ranges, each particle size distribution range differing from the other so a to provide a range of particle sizes wherein the synthetic cellular material comprises from about 25% to about 33% by volume having a means particle size of 1.25 mm with a particle size distribution ranging from 1 to 1.5 mm;
- from about 30% by volume by about 50% having a mean particle size of 2 mm and a particle size distribution from 1.6 to 2.4 mm;
- and from about 25% to about 33% by volume having a mean particle size of 2.7 with a particle size distribution ranging from 2.5 to 3 mm;
- said cementitious material and said sand forming a matrix binding said expanded cellular material into said monolithic form.
