Cement-based grout material and its construction method |
| abstract |
Cement-based grout material that does not freeze even in an environment where the outside temperature is likely to be -5℃ or lower, and does not require large-scale facilities such as a curing mold or fuel to maintain the curing temperature, and ensure quality. to provide. Lithium nitrite is added to the cement-based grout material containing cement, water, and an admixture. By setting the weight ratio of lithium nitrite to the weight of cement to be 3 to 10% by weight, large-scale facilities for maintaining the curing temperature or fuel for heating are used even under the construction environment where the outside temperature at the initial stage of construction is -5°C. It is possible to prevent freezing of the grout material and ensure quality. If the weight ratio of lithium nitrite is 4.5 to 8% by weight, even under a construction environment where the outside temperature at the initial stage of construction is -10°C, large-scale facilities for maintaining the curing temperature or fuel for supplying heat are not used. By preventing freezing, quality can be secured. |
