【Abstract】 The paper presents the fluidization mechanism of permeability-resistant concrete with high workability and discusses from different aspects the effects of the constituent of concrete mix to the rheologic parameters and hardening performance of concrete. Application of this kind of concrete in some instances to the lining in tunneling proved the feasibility of the permeability-resistant concrete with high workability for tunnel lining, which helped to secure good quality and economic benefit.更多还原
