Estimation of Drying Shrinkage of High Volume Fly-Ash concrete Using Early Strength Improvement Admixture

초기강도 향상 혼화재를 사용한 플라이애시 다량치환 콘크리트의 건조수축 해석

The purpose of the study was to analyze dry shrinkage of HVFAC (high volume fly ash concrete) with admixture to improve early strength. The results were as follows. In dry shrinkage of HVFAC with admixture to improve early strength, F3 had the lowest amount of dry shrinkage. The next is in order of Plain, F3-f15 and F3-f15r5. The study used index function modelfor analysis on dry shrinkage. Coefficient of determination was more than 0.97 in all mix, which made it possible to have a good estimation.
