Examples
preparation example 1
[0089] Preparation Example 1: ordinary Portland cement (ordinary Portland cement, OPC)
[0090] Weigh 0.6 parts by weight of magnesium oxide, 141.5 parts by weight of calcium oxide, 51.7 parts by weight of silicon dioxide, 2.1 parts by weight of aluminum oxide and 0.7 parts by weight of iron oxide dried at 105°C for more than 24 hours, and put them into V Shaped mixer (this mixer contains ceramic balls with sizes of 10 mm, 5 mm and 1 mm in a predetermined ratio in the same volume as the material mixture to achieve uniform mixing and pulverization of materials with different particle diameters and specific gravity into a certain size), and then mixed at 50rpm for 4hr.
[0091] After mixing, the ceramic balls were removed, and the resulting mixture was made into a hollow cylinder to achieve a completely homogeneous reaction, and placed in a platinum crucible, fired in a firing furnace at 1,500°C for 1 hour and 30 minutes, and immediately removed from the Take it out of the furn...
preparation example 2
[0094] Preparation Example 2: Cement Containing Silicon Atom Doped Matrix
[0095] The cement of Preparation Example 2 was produced in the same manner as in Preparation Example 1, except that 137 parts by weight of calcium oxide, 45 parts by weight of silica and 18 parts by weight of alumina were used instead of 141.5 parts by weight of Calcium oxide in parts by weight, silicon dioxide in 51.7 parts by weight, aluminum oxide in 2.1 parts by weight, iron oxide in 0.7 parts by weight and magnesium oxide in 0.6 parts by weight.
[0096]The phase analysis of the cement of Preparation Example 2 was performed in the same manner as the phase analysis of the cement of Preparation Example 1.
preparation example 3
[0097] Preparation Example 3: Cement Containing Silicon Atom Doped Matrix
[0098] The cement of Preparation Example 3 was manufactured in the same manner as in Preparation Example 1, except that 141 parts by weight of calcium oxide, 45 parts by weight of silicon dioxide and 14 parts by weight of alumina were used instead of 141.5 parts by weight of Calcium oxide in parts by weight, silicon dioxide in 51.7 parts by weight, aluminum oxide in 2.1 parts by weight, iron oxide in 0.7 parts by weight and magnesium oxide in 0.6 parts by weight.
[0099] The powder phase analysis of Preparation Example 3 was performed in the same manner as the phase analysis of the powder of Preparation Example 1.
