【摘要】：通過測試在規(guī)定的水膠比條件下壓漿料的的流動度、坍落擴展度、粘度三個指標的變化規(guī)律,給出了壓漿料的流動度與坍落擴展度、流動度與粘度的定量關(guān)系。結(jié)果表明:壓漿料的流動度與坍落擴展度,流動度與粘度呈線性變化規(guī)律,滿足JTG/T F50-2011《公路橋涵施工技術(shù)規(guī)范》的壓漿料流動度指標條件下壓漿料的坍落擴展度為356~272 mm,壓漿料的粘度為395×10~(-3)~2023×10~(-3)Pa·s,滿足TB/T 3192-2008《鐵路后張法預(yù)應(yīng)力混凝土梁管道壓漿技術(shù)條件》的壓漿料流動度指標條件下壓漿料的坍落擴展度為308~212 mm,粘度為1325×10~(-3)~3186×10~(-3)Pa·s。坍落擴展度的測試方法簡單和方便,有利于實際工程的應(yīng)用。
[Abstract]:By testing the variation law of flow degree, collapse spread degree and viscosity index under the specified water / binder ratio, the quantitative relationship between flow degree and collapse extension degree, flow degree and viscosity is given.The results show that the flowability and collapse extension, the fluidity and viscosity of the slurry vary linearly.Under the condition of JTG/T F50-2011 (Technical Specification for Highway Bridge and culvert Construction), the collapsing and spreading degree of grouting material and viscosity of grouting material are 356n / 272mm and 2023 脳 10~(-3)Pa / s respectively, respectively, which meet the requirements of TB/T 3192-2008 for grouting technology of Zhang Fa prestressed concrete beam pipe after railway.Under the condition of the flowability index of the pressure-size, the collapsing and spreading degree of the compacted slurry is 308 ~ 212mm, and the viscosity is 1325 脳 10 ~ (-1) -3186x 10~(-3)Pa ~ s.The test method of collapse extension is simple and convenient, which is propitious to the application of practical engineering.
