Abstract
The invention provides modified stonework material as well as modified woven fabric, paper, and ligneous materials with improved water-proof, dust-prevention, wear-resistance, and others. These porous materials are rendered non-porous by causing aqueous solution of alkali silicate to penetrate into such porous materials to produce calcium silicate and colloidal silicic acid in the presence of ammonium ions and halogen ions, the solution of which fills the voids in the material perfectly to render it non-porous.
