▎ 摘  要

NOVELTY - Cement-based spray slurry comprises main materials composed of 30-35 pt. wt. cement, 20-25 pt. wt. aggregate, and 50-55 pt. wt. carboxy materials and auxiliary materials composed of 10-15 pt. wt. styrene-acrylic emulsion and 2-7 pt. wt. expansion agent. USE - The cement-based spraying slurry is useful for repairing inspection well of a building. Can also be used in a residential building, a commercial building, an industrial building and a military building. ADVANTAGE - The method: improves the constructability and physical and mechanical properties, and strength of the mortar; avoids the segregation of the mortar; prevents the mortar from flowing down the inspection well after spraying; increases the initial setting speed and water-reducing rate of the mortar; reduces the bulk density of the freshly mixed mortar; and makes the durability of the quickly repaired concrete better.
