中華民國發明專利第 I768210 號
The disclosure provides a method for forming a functionally graded cement-based cementitious material, including a mold, in which the cement paste is poured, electroosmotic reaction conducted on the cement paste, and transfer of the cement pastes into the water tank for curing to obtain a cement-based cementitious material with functionally graded properties. The disclosure also provides a cement-based cementitious material formed by the above method. The compressive strength in the middle of the cement-based cementitious material is smaller than those at both ends.
US Patent No. 11,492,297
CEMENT-BASED CEMENTITIOUS MATERIAL AND ITS FORMATION METHOD
A method for forming cement-based cementitious material includes: pouring a cement paste into a mold; applying an electrical current to the cement paste to perform an electro-osmotic reaction; and transferring the reacted cement paste into a water tank for curing, thereby obtaining a functionally graded cement-based cementitious material. A pair of electrodes is placed in the mold and connected to an external power source. The compressive strength of the functionally graded cement-based cementitious material in the middle is lower than that at either of both ends.
