<p>PROBLEM TO BE SOLVED: To provide a long-term strength suppressed type curing material which shows good developing property for the initial strength and shows small increase in the strength after the initial stage. SOLUTION: A mixture is prepared by mixing 10 to 30wt.% portland cement, 20 to 40wt.% rapid-curing admixture, 20 to 30wt.% long-term strength suppressing material and 20 to 30wt.% fluidizing agent. In this method, 50wt.% of the whole material consists of the portland cement and the rapid-curing admixture, while the remaining 50wt.% consists of the long-term strength suppressing material and the fluidizing agent. Thus, a long-term strength suppressed type curing material which shows good developing property of the initial strength and shows small increase in the strength in the succeeding stage can be obtd. The obtd. material is used, for example, for an erection road.</p> |
