  2. 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。
