摘要
Abstract
The experiment explored the advantages of ultra-high performance concrete specific fibers over ordinary polypropylene fine fibers in terms of physical and mechanical properties.The fiber has a large size,high elastic modulus,good stiffness,and is evenly dispersed in concrete.It can significantly improve the mechanical properties of engineering structures,especially the bending and tensile resistance,while enhancing durability and reducing self weight.Through comparative experiments,the superiority in practical applications has been verified.The results of this experiment have been successfully applied to the concrete pouring of the rock wall crane beam in the underground powerhouse of TB hydropower station.关键词
