| titleOfInvention | Improvements in or relating to the production of porous building materials |
| abstract | Porous materials containing hydraulic binding agents are prepared by utilising as foaming agents sulphite lyes of the cellulose industry or solutions of plant extracts such as horse-chestnut and acorn extracts to which have been added compounds yielding alkaline earth ions, particularly calcium ions, prior to converting the solution into a foam. When the solution of foaming agent is acid, sufficient alkaline earth compound having an alkaline reaction is added to render the solution alkaline. In alternative processes, the hydraulic binding agent or mixture of binding agent and aggregate, such as sand, may be mixed dry with the mineralised solutions of the foaming substances, which solutions may be diluted with water or an aqueous solution of waterglass, and the resulting suspension converted into a foamy slurry by introducing compressed air, or a foam may be first produced from the mineralised solution which p foam is then incorporated with the hydraulic binding agent, or the mineralised solution of foaming agent may be evaporated to dryness and the dried product used for the production of foam e.g. by adding it to the wetting fluid and/or to the components of the building material, and subjecting the mass to foaming. The porous mass obtained after setting may be crushed and used as addition to hydraulic building materials. Specification 588,524 is referred to. |
