CEMENT GROUT MATERIAL AND INSTALLATION METHOD OF SAME
A cement grout material is provided, which does not freeze even in an environment where the ambient temperature can be -5°C or below, thereby ensuring the quality, and which does not require a fuel or large-scaled equipment such as a curing enclosure for maintaining the curing temperature. Lithium nitrite is added to a cement grout material that contains cement, water and an admixture. By setting the weight ratio of the lithium nitrite to the cement to a value from 3 to 10% by weight, freezing of the grout material is able to be prevented so as to ensure the quality without need to use any large-scaled equipment for maintaining the curing temperature or any fuel for heating even in an installation environment where the ambient temperature can be -5°C during the initial stage of installation. By setting the weight ratio of the lithium nitrite to the cement to a value from 4.5 to 8% by weight, freezing of the grout material is able to be prevented so as to ensure the quality without need to use any large-scaled equipment for maintaining the curing temperature or any fuel for heating even in an installation environment where the ambient temperature can be -10°C during the initial stage of installation.
