摘要
机制砂在颗粒形态、细度模数、物理性质和化学成分等方面与河砂有明显不同。本文从机制砂的细度模数和颗粒级配、压碎指标值和轻物质含量、试块强度和实体强度方面对机制砂在PHC管桩的应用进行了研究。
The manufactured sand is obviously different from the river sand in particle morphology,fineness modulus,physical properties and chemical composition.In this paper,the application of the manufactured sand in PHC pipe piles is studied in terms of fineness modulus,grain composition,crushing value,light substance content and concrete cubes strength,etc.
