Title: Method of preventing breaking of soft rock
Inventor: ISHIKAWA YOSHIO
IPC: C09K17/00
Filed: 1987-11-09
Abstract: PURPOSE:To prevent the breaking of a soft rock upon being exposed to the air, by coating the whole surface of a rock with a water-impermeable material either immediately when the rock is mainly composed of a kaolinite mineral or after a particular treatment when the rock is composed of a smectite mineral. CONSTITUTION:A soft rock is examined to ascertain whether it is mainly composed of a kaolinite mineral or a smectite mineral, by, e.g., dropping p- phenylenediamine on the surface of a soft rock. In this case, when the color of the rock surface turns deep blue or green, the rock is judged to be a smectite mineral, while when the color remains unchanged, the rock is judged to be a kaolinite mineral. When the rock is a kaolinite mineral, the whole surface of the rock mass is immediately coated with a water-impermeable substance (e.g., tar derived from coal or petroleum, a boiled oil, a synthetic resin emulsion, or a silicone water-repellent). On the other hand, when the rock is a smectite mineral, an aq. alkali silicate soln. is applied to the whole surface of the rock mass and then an aq. soln. of a salt of Mg, Al or ferric iron is applied. The resulting surface is air dried and coated with a water-impermeable material.
