桥梁支座灌浆料研发及物理性能研究

Research and Development of Grouting Material for Bridge Support and Its Physical Properties

如今高速公路、高铁建设高速发展,桥梁支座在桥梁的受力体系中处于重要部位。为了加快施工进度,需桥梁支座灌浆料具备快硬、早强、高强等特性。本文主要通过对桥梁支座灌浆料研发及物理性能研究得出满足施工要求的配合比。

Nowadays,with the rapid development of expressway and high-speed rail construction,bridge supports are in an important part of the stress system of Bridges.In order to speed up the construction progress,the bridge support grouting material should have the characteristics of fast hardness,early strength and high strength.This paper mainly through the research and development of bridge support grouting material and physical properties to obtain the mix ratio to meet the construction requirements.
