Industrial Test on Outer Frozen Shaft Wall of High Strength and High Performance Concrete
To study the industrial technology for application of the C100 High strength and high performance concrete which is in freezing shaft lining of thick overburden, the industrial test of the shaft wall of high strength and high performance concrete is carried out under the engineering background of auxiliary shaft in Yuncheng coal mine of Juye coal mining area in Shandong Province. The verified laboratory testing results comported with the results of industrial technology from macro-mechanics, failure fractal, resultant morphology and pore characteristics. And the quality control system of high performance concrete and construction technology can be established. The results show that the experimental formula and construction technology of C100 high strength and high performance concrete can meet the requirement of field concrete shaft lining and achieve the high level of quality control. The industrial application and study results accord with the field requirement. Furthermore, the study results also provide experimental basis and industrial production data for industrial application of C100 high strength and high performance concrete.
