Abstract
A portable constructional element (4) comprising a foamed cementitious material (8) in an outer plastics covering (10), the foamed cementitious material (8) being such that it has been introduced into the outer covering (10) in a wet state and has set in the outer covering (10) such that the foamed cementitious material (8) is of a substantially uniform character throughout the constructional element, and such that the outer covering (10) forms an integral part of the portable constructional element (4).
Claims9
A portable constructional element comprising a foamed cementitious material in an outer covering, the foamed cementitious material being such that it has been introduced into the outer covering in a wet state and has set in the outer covering such that the foamed cementitious material is of a substantially uniform character throughout the constructional element, the outer covering being made of a plastics material, the outer covering having an inner surface which is free of inward deformations acting solely to key the foamed cementitious material to the outer covering, the outer covering and the foamed cementitious material being secured to one another by the setting of the foamed cementitious material in the outer covering, and the foamed cementitious material being such that it comprises a foaming agent and cement.
A process for the production of a portable constructional element, which process comprises providing an outer covering which is made of a plastics material, filling the outer covering with foamed cementitious material in a wet state, allowing the wet foamed cementitious material to set such that the foamed cementitious material is of a substantially uniform character throughout the constructional element, the outer covering being such that it has an inner surface which is free of inward deformations acting solely to key the foamed cementitious material to the outer covering whereby the outer covering and the foamed cementitious material are secured to one another by the setting of the foamed cementitious material in the outer covering, and the foamed cementitious material being such that it comprises a foaming agent and cement.
