  1. 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環境及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,開展一系列包括硫鹽侵蝕、氯離子滲透、抗凍融循環、收縮及磨性等久性能研究;通過對fd - 1組分和摻量的調整,優化負溫混凝土在施特性、力學指標和久性三個方面的兼容、協調性。
  2. For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete

    實際程中的混凝土結構,因侵蝕性介質的存在而使非力學破壞行為無處不在,這些非力學破壞行為包括堿集料反應、硫鹽侵蝕、碳化、鋼筋銹蝕、凍融等,單一的破壞形式或多形式的復合破壞用對混凝土結構性能及久性能均有著較為嚴重的影響,在很大程度上縮短了建築物的役年限,而這些非力學破壞在很大程度上取決于其滲透性,所以測試混凝土滲透性能是研究判斷混凝土久性的常規必測項目。
