  3. Following is the factors ideating with the surface of old concrete in different way ( including brushing surface, chiseling surface, cleaving surface ), adherence agent ( including cement slurry, cement sand slurry, cement slurry with the u expansion agent ), the freeze - thaw circulation times and air - entraining. as a result, we found that the roughness influence on the adhesion capability of the new on old concrete to a large degree. the larger rougeness is, the larger the splitting tensile strength on the adhension face is. the kind of adhesion agent is also influence on the adherence capability of new on old concrete. the circulation times of freez - thaw have a large influence on the splitting tensile strength of adherence face of new on old concrete. the analysis of tests give some advices to the practical engineering

    主要考察了老混凝土表面不同處理方式（刷毛面，鑿毛面，劈裂面） 、界面粘結劑類型（水泥凈漿，水泥砂漿， u型膨脹劑水泥漿） 、凍融循環次數等對新老混凝土粘結面劈拉強度的影響，以及凍融作用下新混凝土加氣對粘結面劈拉強度的影響。試驗結果表明，粗糙度對新老混凝土粘結性能有重要影響，隨著粘結面粗糙度的增大，粘結面劈拉強度不斷增加；界面粘結劑類型對新老混凝土粘結性能有一定影響，在凍融作用下， u型膨脹劑水泥漿粘結效果不如水泥凈漿和水泥砂漿；凍融循環對粘結面劈拉強度有較大影響，加氣能明顯改善新老混凝土粘結面的抗凍能力。

  6. The paper discusses mechanism performance, durability and resistance to de - icing salt concrete, this kind of concrete is made with air - entraining agent or silica fume and used in the trial section construction of benxi - dandong freeway ' s charge square which is located in dandong

    本文通過在混凝土中摻入引氣劑或硅粉，來配製抗除冰鹽混凝土，並對其進行力學性能和耐久性測試，重點試驗其抵抗鹽凍能力，並用於本丹高速公路丹東段的收費廣場試驗路施工。
  7. This paper unfolds engineering disposition and theoretical research of negative temperature high performance concrete ( nthpc ) with the damage of many factors motivation, the project background based on qing - zang railway engineering, which is one of four - emphasized engineering during the tenth five - plan. due to the difference of environment of construction and service between nthpc and ordinary concrete, and therefore durability of nthpc is required to higher level. at a first, nthpc must avoid frozen damage at early age and possess anti - freezing property at later period, in order to meet engineering practicable application need, and this are two emphasized and difficult problems, as for nthpc ; by means of mechanism analysis about deicing - agent ingredient and anti - freezing at early period, adopting composite technique routine of mineral addition + anti - freezing element + water - reducer4 - air - entraining + anti - erosion of steel component etc, based on orthogonal experimental approach, fd - 1 composite functional admixtu re was manufactured, which has more property and orientation on qing - zang railway

    負溫混凝土由於和普通混凝土在施工環境及服役環境上存在的差異，因此表現為比普通混凝土更為較高的耐久性要求；負溫混凝土首先要避免早期的凍害以及具備長期抗凍性能，才能夠滿足工程實際應用的要求，這也是負溫混凝土必須解決的兩大技術關鍵；通過對目前常用防凍劑組分作用機理的分析研究及混凝土早期防凍機理探討，採用礦物外加劑+防凍組分+高效減水劑+引氣+阻銹組分功能復合的技術路線，通過正交試驗設計復配了適應青藏鐵路工程要求的專用多功能復合型外加劑fd - 1 ；並在此基礎上配製不同等級負溫高性能混凝土，開展一系列包括硫酸鹽侵蝕、氯離子滲透、抗凍融循環、收縮及耐磨性等耐久性能研究；通過對fd - 1組分和摻量的調整，優化負溫混凝土在施工特性、力學指標和耐久性三個方面的兼容、協調性。
