| Abstract |
The study on the strength prediction using Maturity is the normal strength concrete mostly, but the study on the high strength concrete is inadequacy. The purpose of this study is to investigate the relations between compressive strength and equivalent age by Maturity function, and is to compare and examine on the strength prediction of high strength concrete using Powman's, Gompertz's and Kim's prediction equation. So it is intended that fundamental data were presented for quality management and process management of high strength concrete in the construction field. The results are as follows: It is considered that the strength prediction is possible using maturity function,??because it was similar to the level of strength in the same equivalent age without curing temperature. Also, because the actual strength and prediction strength were generally similar to in the W/C ratio of 27, 32, 37% in case of Gompertz's and Kim's prediction equation, it is considered that the strength prediction of high strength concrete is possible using Gompertz's and Kim's prediction equation. |
