Process for treating porous materials and products obtained |
摘要 |
A method for processing porous materials with at least one water-insoluble polymerizable compound and the products obtained, said method comprising the following steps in successive order: impregnating a porous material, especially one consisting essentially of a hydraulic binder and a granular or fibrous filler, with said compound; fully covering the thus impregnated material with an aqueous solution of a salt which precipitates when contacted with the hydraulic binder; and polymerizing the compound in the impregnated material while covered with the saline solution.
