高温环境下预应力T梁混凝土性能研究及温度监测

Research on Performance of Prestressed T-beam Concrete and Temperature Monitoring in High Temperature Environment

针对高温河谷地区C50预应力T梁混凝土坍落度损失快,易产生温度裂缝等问题,通过严格控制原材料质量,采用矿物掺合料复掺技术,探究矿渣粉掺量对混凝土性能的影响规律,并通过温度监测仪对T梁芯部及表面温度实行全天候监控,确保C50预应力T梁混凝土施工浇筑过程顺利进行及质量保证。

Aiming at the problems of rapid slump loss of C50 prestressed T-beam concrete and temperature cracks in high-temperature river valley areas,through strict control of the quality of raw materials,this article uses mineral admixture technology to explore the effect of slag powder content on concrete performance,and conducts all-weather monitoring of T beam core and surface temperature by temperature monitor to ensure the smooth progress of the C50 pre-stressed T-beam concrete construction and quality assurance.
