高性能混凝土拌和用水温度控制

Temperature Control of Mixing Water for High Performance Concrete

在客运专线大型箱梁施工过程中,为确保混凝土入模温度满足规范要求,采用冷凝机对拌和用水进行降温。通过研究发现,该设备不仅能有效控制混凝土拌和用水温度,而且性能良好,经济适用性高,对混凝土质量控制和工程进度保障具有积极的促进作用。

In the perature of high pe large box beam construction of passenger dedicated line, in order to ensure the molding tem- rformance concrete to meet the standard requirement, condensing machine was used to reduce the temperature of mixing water. Through researching not only can control the mixing temperature efficiently, on condensing machine, it was found out that the machine but also has good performance, economy and applicability, which can promote quality control and guarantee the project schedule
