随着环保和可持续理念的认同,在混凝土工程中机制砂得到较为广泛的应用。本文基于工程实践和试验现象与数据分析机制砂在混凝土工程中的力学性能。结果表明:混凝土机制砂控制指标为压碎指标≤25%;细度模数在2.6~3.2;石粉含量在4~6%之间;砂含量>70%,生产工艺采用湿法生产。机制砂混凝土配合比设计思路能够充分发挥掺和料外加剂的作用,对混凝土工程设计及应用具有一定参考价值。

Machine-made sand has been widely applied in concrete engineering with the environmental protection and sustainable concept in mind. This paper analyzed the mechanical properties of machine-made sand in concrete based on the experimental phenomena and data. the results showed that the control parameters were crush indexes which were less than or equal to 25%, the fineness modulus at 2.6 ~ 3.2, stone powder content in 4 ~ 6%, sand content was more than 70%. The manufactured process took up wet process production. The design of machine-made sand in concrete could fully play a role of admixture to provide a reference for mechanism of sand concrete ratio design and application.
