Different ratios of slag content and different water to cement ratios (w/c) were used to evaluate the effects of slag content on the grout. The experiments included compressive strength, flexural strength, shear strength of sand grouts, stability and fluidity of net grouts. It was found that compressive strength, flexural strength and shear strength of sand grout increase with slag content. However, there exists an optimum formulation for a specific w/c. while the w/c is less than 2, the optimum slag content ranges from 50% to 70%; while w/c is between 3 to 5, the optimum slag content ranges from 40% to 50%. It was also found that the stability and the fluidity of net grout are affected by slag content. The higher the slag content, The higher the stability and the lower the fluidity. It is noticeable that while w/c ranges from 3 to 5, long term strength of the grout increases significantly because of the existing of slag in the grout, i.e. while w/c are different, the grouts are affected differently because of the slag added to the grouts.誌謝......................................................i 中文摘要.................................................ii 英文摘要................................................iii 圖目錄...................................................vi 表目錄.................................................viii 第一章　研究動機與目的....................................1 1.1 研究動機..............................................1 1.2 研究目的..............................................2 第二章　文獻回顧..........................................4 2.1 超微粒水泥之發展......................................4 2.2 基本材料性質及應用....................................5 2.3 研磨攪拌技術方面.....................................10 2.4 配比成分影響.........................................12 2.5 卜作嵐效應方面.......................................16 第三章 研究方法.........................................20 3.1砂漿單壓及抗彎試驗....................................20 3.1.1試驗材料及設備......................................20 3.1.2試驗流程............................................26 3.2砂漿抗剪試驗..........................................29 3.2.1試驗材料及設備......................................29 3.2.2試驗流程............................................31 3.3淨漿穩定性試驗........................................35 3.3.1試驗材料及設備......................................35 3.3.2試驗流程............................................36 3.4淨漿流動性試驗........................................37 3.4.1試驗材料及設備......................................37 3.4.2試驗流程............................................37 第四章 結果與討論.......................................40 4.1砂漿單壓強度..........................................40 4.1.1以水灰比做為控制變因................................40 4.1.2以爐石添加量做為控制變因............................49 4.2砂漿抗彎強度..........................................52 4.2.1以水灰比做為控制變因................................52 4.2.2以爐石添加量做為控制變因............................59 4.3砂漿抗彎強度..........................................59 4.3.1以水灰比做為控制變因................................60 4.3.2以爐石添加量做為控制變因............................61 4.4淨漿穩定性............................................62 4.4.1以水灰比做為控制變因................................62 4.4.2以爐石添加量做為控制變因............................65 4.5淨漿流動度............................................68 4.6綜合比較..............................................69 第五章 結論與建議 ......................................72 5.1 結論.................................................72 5.2 後續建議.............................................73 參考文獻.................................................75 附錄.....................................................784694463 bytesapplication/pdfen-US超微粒水泥爐石單壓強度抗彎強度抗剪強度穩定性流動性microfine cementslagcompressive strengthflexural strengthshear strengthstabilityfluiditythesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/56120/1/ntu-96-R94622033-1.pdf
