| Research Abstract |
Shrinkage characteristics of high shrinkage concrete which induced unprecedented cracking in a real concrete structure, shrinkage effects on air permeability of reinforced concrete prism shear strength of reinforced concrete beam under sustained tensile load and so on were investigated, which were made with the high shrinkage concrete. Results showed that the drying shrinkage of concrete depended on the drying shrinkage and Young' s modulus of aggregates, the air permeability of concrete increases with the increase of drying shrinkage, the shear strength of reinforced concrete beams is decreased by the shrinkage developed before loading when the reinforcement ratio is nearly 1. 0%.
