本文通过对机制砂干混砂浆生产过程中进厂原材料、中间产物、出厂砂浆的过程控制,分析了干混砂浆与预拌混凝土质量控制的区别,建立过程控制是实现干混砂浆质量稳定可靠保证的观念,尤其是对过程中间产物机制砂更应建立以形貌、颗粒级配等为中心的质量控制手段,抛弃强度唯一的错误做法,适应机制砂为核心,水泥为主要胶凝材料的过程控制检测方法,得到以干混砂浆生产工艺为基础的过程控制体系。 In this paper, through the process control of raw materials, intermediate products and manufactured mortar in the process of production of dry sand mixed mortar, the difference of quality control between dry-mixed mortar and ready-mixed concrete is analyzed. The establishment of process control is to ensure the quality of dry-mixed mortar stable and reliable Especially for the process of intermediate product sand should be established with the topography, particle size distribution as the center of the quality control measures, the only way to abandon the intensity of error, to adapt to the mechanism of sand as the core, the process of cement as the main cementitious material Control testing methods, to be dry mortar production process-based process control system.
