Stress Development and Crack Monitoring of Massive Concrete Walls with Embedded Air-cooling Pipes

Thermal cracking is a severe problem faced with massive concrete structures especially in early ages. In order to control the temperature distribution and lower cracking risk of a large-dimension reinforced concrete wall during construction, air pipe cooling was applied to experimental concrete walls with embedded corrugated pipes. Three levels of inlet airflow velocity (about 4, 8, and 12 m/s) were studied and compared with the wall without...
