<p>PROBLEM TO BE SOLVED: To provide a method of estimating a structure concrete strength using an ultra-high-strength concrete according to a compression strength of an initial material age.SOLUTION: An early estimation method of a structure concrete strength using an ultra-high-strength concrete is to estimate a compression strength of an ultra-high-strength concrete sample with a material age of seven days that has underwent (A) a pre-curing process, (B) a temperature rising process, (C) an insulated curing process, and (D) a temperature dropping process by regarding as a structure concrete strength of an ultra-high-strength concrete containing the same materials with the same blending with a material age of 91 days.</p> |
