STRATIFIED CEMENTITIOUS COMPOSITE
First Claim
1. A method for forming a stratified cementitious body comprising placing into a mold a cementitious slurry comprising a cementitious binder, to form the body in a single pour and curing the slurry to form a stratified cementitious body, the slurry having a yield sheer stress of less than about 300 Pa and plastic viscosity of less than about 70 Pa·

Abstract
The present invention relates to a method for forming a stratified cementitious body comprising placing a cementitious slurry comprising a cementitious binder, to form the body in a single pour and curing the slurry to form a stratified cementitious body. The method may also comprise the steps of mixing a cementitious binder and at least one aggregate material with water to form a slurry, pouring the slurry into a mould, allowing the slurry to stratify into layers under the influence of gravitational forces and/or buoyancy forces, optionally applying vibrations to the slurry to encourage the slurry to stratify into layers, and curing the slurry to form a stratified cementitious body.

54. A cured stratified cementitious panel comprising:
-
a more dense aggregate material layer forming about one third of the overall thickness of the panel (the structural layer) and a less dense aggregate material layer forming about two thirds of the overall thickness of the panel (the insulating layer), the stratified cementitious panel having been formed from a slurry in a single pour, said slurry comprising a cementitious binder, the more dense aggregate material, the less dense aggregate material and water. - View Dependent Claims (55, 56, 57, 58, 59)
