Preparation Experiment and Engineering Application of High Performance Concrete of Freezing Shaft in Deep Alluvium

摘要

According to the special construction environment and curing conditions of the freezing shaft inner and outer shaft lining in deep alluvium, first, configuration principle of high strength high performance concrete of freezing shaft in deep alluvium is proposed; Then raw materials are selected according to the preparation approach, and preparation experimental study of high strength high performance concrete is conducted with C60, C65, C70 and C75, and the optimum mixture ratio is obtained, and applied to the engineering practice, achieving remarkable effect.
