干热河谷气候环境对碾压混凝土性能的影响研究
Research on the Effect of Dry and Hot River Valley Climate Environment on the Property of Roller Compacted Concrete
摘要
Abstract
A large-scale walk-in extreme climate simulator is used to simulate the complex climate conditions of low humidity and intense sunlight in the dry and hot river valley region,and the researches are carried out on the evolution law of mechanical and volume deformation properties of roller compacted concrete for dam construction.The results show that the dry and hot valley climate environment has a great influence on the cubic compressive strength,axial compressive property and axial tensile property of three-graded dam RCC.The shorter the standard curing time for concrete,the more significant the decrease in its mechanical property under the effect of the dry and hot river valley climate environment.The drying shrinkage deformation of three-graded dam RCC in the dry and hot river valley climate environment follows a hyperbolic model evolution low,so special attention should be paid to strengthen the early-stage curing during the implementation of roller-compacted concrete projects in the dry and hot river valley region.关键词
