Claim 1:
2. A method for preparing a barium slag-modified aluminate quick-hardening cementing material, comprising:
mixing, in parts by weight, 10-12 parts of aluminate cement clinker, 2-3 parts of barium slag powder, 1.5-2 parts of sulfate material, and an early-setting agent, and then adding water and stirring until uniform to obtain the barium slag-modified aluminate quick-hardening cementing material, wherein the early-setting agent is present in an amount greater than zero and up to 1.5 parts and wherein the sulfate material and the early setting agent are different; and
wherein a mass ratio of the added water to solid components is 0.3-0.5.
