Mineralization method of dolomite on inner surface of porous medium material and product thereof

The invention provides a mineralization method of dolomite on an inner surface of a porous medium material and a product thereof. The method comprises the following steps: (1) in a container, the porous medium material is totally dipped in dolomite mineralization liquid under the vacuumizing condition; preferentially, the porous medium material is put in the container; the container is vacuumized; and then, the dolomite mineralization liquid is injected in the container, so that the porous medium material is totally dipped in the dolomite mineralization liquid; (2) after the container is vacuumized, the pressure is kept by a period of time, then, the normal pressure is recovered, and internal space of the porous medium material is fully filled with the totally saturated dolomite mineralization liquid; and (3) the temperature or the pressure in the container is increased for keeping by a period of time to finish mineralization of the dolomite on the inner surface of the porous medium material; and then, the no
