The includes one or more phosphate compounds selected from a group of monocalcium phosphate anhydrous, monocalcium phosphate monohydrate, dicalcium phosphate anhydrous, dicalcium phosphate dihydrate, amorphous calcium phosphate, α-tricalcium phosphate, β-tricalcium phosphate, and tetracalcium phosphate. The cement liquid is an aqueous phosphate solution having a total phosphate concentration in a range of 0.005 to 2.4 moles per liter (mol/L).
