Abstract
Disclosed is an accelerated petrifaction process of lignocellulose materials, including the step of impregnating with an aqueous solution an alkaline hydroxide and a soluble silicate, under pH conditions that permits its partial neutralization and insolubilization of the salts in situ in the interior of the lignocellulose material by the action of acid groups present in the lignocellulose material and the acidic action of carbon dioxide present in the surrounding air.
