The phosphate esters are preferably phosphate esters of polyoxyalkylene alkyl ethers. The liquid quick-setting agent may contain a fluorine compound, alkanolamines, a compound containing a hydroxyl group, and carboxylic acids. In a spraying method, the cement concrete and the liquid quick-setting agent are mixed and sprayed. |
