<p>The present invention relates to a rapid-hardening water-holding mortar composition containing 20-38 wt% of microcement, 10-20 wt% of calcium sulfo-alumninate, 5-10 wt% of gypsum, 20-35 wt% of ganister sand, 20-30 wt% of slag, 0.01-0.1 wt% of a plasticizer, 0.1-1 wt% of an antifoamer, 0.1-1 wt% of an accelerator, 0.05-0.2 wt% of a retarder, and 1-3 wt% of a water reducing agent, and a construction method using the same. Provided in the present invention is the rapid-hardening water-holding mortar composition having a high-performance of the bending performance, and having the excellent bond strength between old and new, and the excellent durability, and reducing the construction time by being rapidly hardened during the construction.</p> |
