HCSA高性能混凝土膨胀剂在准朔铁路跨黄河特大桥工程中的应用

Application of HCSA expansive agent for concrete in Zhun shuo railway across yellow river bridge project

本文介绍了准朔铁路跨黄河特大桥工程在施工过程中,针对工程特点与技术要求,采用高性能的膨胀剂,并通过与施工相近的模拟试验的方法,对混凝土配合比进行优化设计,确定最佳技术方案,精心组织施工,从而取得了良好的效果。

This paper introduces the construction of Zhunshuo railway bridge across the Yellow River project. According to the engineering characteristics and technical requirements, high performance expansive agent was adopted, and a similar construction simulation was also used to optimize the mix design of concrete and determine technical solution. Good results was obtained by well-organized construction and the above measures.
