▎ 摘  要

NOVELTY - Alkali-free liquid setting agent comprises 385-405 pts. wt. aluminum-containing solution, 0.5-1 pts. wt. few-layer graphene dispersion liquid, 10-15 pts. wt. coagulant aid and 10-20 pts. wt. pH regulator. USE - Alkali-free liquid setting agent is useful for spraying concrete (claimed). ADVANTAGE - The alkali-free liquid setting agent has high compressive strength, short initial final coagulation time and low production cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing alkali-free liquid setting agent.
