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.
