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。The liquid - gas method is improved based on the above methods, overcoming the defects of gbj82 - 85. using the liquid - gas method, permeability condition of concrete can be tested and indicated quickly, efficiently, and the influences on concrete of alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw can be inflected indirectly. it is significant on the research and monitor on the durability of concrete
溶液氣壓法是在上述方法之上進行改進提高的，克服了國標gbj82 - 85方法中的許多不足之處，能夠多角度、快速、高效、真實、準確地再現現場混凝土的滲透情況，並且能間接反映堿-骨料反應、鋼筋銹蝕、碳化、硫酸鹽侵蝕及凍融破壞的影響，對混凝土耐久性的監測與研究具有重要意義。The results show that the chosen test variables have no effect on the activity of methane, except that the activity refeering to the blast limit was restrained at a certain extent by nitrogen and carbon dioxide adulteration
結果表明，甲烷活性隨貯存時間的延長沒有變化，甲烷通過水、硫酸、氫氧化鈉洗氣后活性沒有變化；氮氣、二氧化碳在一定程度上可抑制甲烷與空氣混合爆炸，且二氧化碳的影響稍大；氨氣則沒有影響。Ore - forming fluid, mineralizing agent, auxiliary aget came mainly from the mixing of deep - source bittern, formation water, palaeometeoric water. ( 5 ) when sinking palaeometeoric water and rising deep - source solution mixed during their moving, their physicochemical condition was changed, which made ore - forming
下滲的大氣降水與上升的深源流體在運移過程中混合，使得溶液的溫度、 ph值、 h _ 2s的濃度、硫逸度、氧逸度以及氧化還原電位改變，從而發生成礦作用。By using gc - ms, the result showed that the gaseous substances are the mixture of organic acids and a compound as a byproduct in the reaction of vitriol oil and phenol
纖維類廢棄物的熱化學液化反應過程中，產生了一類低沸點的氣態混合物。經gc - ms檢測，結果顯示氣態混合物為一類有機酸的混合物和苯酚-硫酸形成的化合物。Influences of hydrogen sulfide, element sulfide, mercaptan, sulphuring ether, disulfide individually on silver strip corrosion of jet fuel, and of element sulphur coexisting with other sulfide on silver strip corrosion of jet fuel were studied
考察了硫化氫、元素硫、硫醇、硫醚、多硫化物等單獨存在時對噴氣燃料銀片腐蝕的影響；同時研究了元素硫與其它硫化物以不同濃度混合時對噴氣燃料銀片腐蝕的影響。分享友人
