い出し、本発明を完成したものである。The Ministry of the Invention and others are behind in workability at room temperature, and
Workability and strength development can be significantly improved even in a construction atmosphere of 50°C or higher.For example, it has sufficient workability for pouring even in a construction atmosphere of 50°C, and casting within 24 hours. Regarding the development of alumina cement that can obtain sufficient strength 2 (after repeated revisions, we discovered that water-soluble non-aggressive fluoride has a long-term effect 2), and completed the present invention.
