Abstract
Recently, the massive concrete structures have been increasingly built in Korea. Many reinforced concrete structures have been reported to suffer from cracking in construction stages due to heat of hydration arising from mass concrete. This cracking may cause some serious durability problems and thus reduces the safety and service life of the structures. In this study, the stresses, strains, and temperatures were measured and the crack widths and crack Patterns were also observed in the footing and abutment structures. And the causes and mechanism in thermal cracking in the footing and abutment structures are thoroughly analysed. The comparisons of test results with analysis have been made. Efficient crack control techniques were developed form the experimental and analytical studies.
