초록

High-Strength Concrete Shrinkage in early age intense hydration in order to prevent shortages of water required for the unit mix to some extent by external factors other than speed and quantity of supply is important. And in cementious by-product porous structure containing large amounts cured paste that conservatism is expected to be the source of moisture, cementitious by-product shrinkage reduction effect of using a high-strength concrete on the first phase of the study itself, cementitious by-product release of water, check the water supply that is likely to be decided. In this study, the level of cementitious by-product that can be controlled by producing models, high-strength concrete hydration process that occurs in the initial response to the shortage of water in fine grained in order to demonstrate the possibility of hydration of the pore structure itself to determine the evaporation rate of water through experiments on the movement of moisture over time was visualized.
