以国家重点工程昆明新机场水泥道面混凝土工程为例,介绍了高性能水泥道面混凝土工程集中供料与质量控制技术。从搅拌站日常管理、选址布置、原材料选择控制、配合比设计、施工质量控制等方面对集中供料模式进行了详细阐述。该工程集中建设9条240m~3/h的混凝土生产线,通过有效的生产组织管理、原材料质量控制,在4个月内生产F4.5、F5.0水泥道面混凝土达926 147m~3,产品质量满足了工程设计要求,为混凝土集中供料生产提供了参考数据。
Taking the concrete pavement concrete project of Kunming New Airport, a national key project, as an example, the centralized feeding and quality control technology of high performance concrete pavement concrete is introduced. From the day-to-day management of the mixing station, site selection, raw material selection control, mix design, construction quality control and other aspects of the centralized feeding mode were described in detail. The project focuses on the construction of 9 240m ~ 3 / h concrete production lines. Through effective production and management of raw materials and quality control, F4.5 and F5.0 concrete pavement concrete are produced in 9 months and 926 to 147m3 respectively within 4 months. The quality meets the engineering design requirements and provides reference data for the centralized production of concrete.
