摘要
以广东省某高速公路建设为依托,根据《公路桥涵施工技术规范》(JTG/T F50——2011),对后张预应力孔道压浆浆液的性能指标进行试配试验,发现传统压浆材料不能满足新的桥涵施工规范要求,提出在实践中将新型压浆剂掺量设为9.1%较为经济实用。
Based on the construction of an expressway in Guangdong, the experimental study on performance requirements of duct grouting materials of post-tension was carried out according to the specification of Tech- nical Specification for Construction of Highway Bridge and Culvert （ JTG/T F50--2011 ）. It is discovered that the traditional grouting material does not apply to new technical specification, and it is more economical and practical when setting new grouting agent mixing content to 9.1%.
