特別添加的竹鹽成份和凡士林，含有天然的防裂保濕因子，加強皮膚表層水份，防止皮膚乾裂和預防凍瘡產生。The investigation of a lot of parameters about treated sandstone, brick materials and earthen materials with fluorited polymers has been carried out, such as the formation of polymer, the penetration depth, porosity, capillary absorption and penetration coefficient, water uptake, compressive strength, drilling resistance, absorption isotherms of water vapor, water vapor diffusion, color changes as well as resistance to desegregation of water, frizzing - throwing cycles, worming - cooling cycles, and so on. in addition, the influence of salt crystallization, acid and base, and uv aging have also been assessed in order to better understand the protection effects and utilization possibility of two fluorinated polymers, mainly according to astm standard and the combination of international methods together with general technological
分別以國家級文物保護單位的土質、砂巖和磚材文物樣品為對象，依據astm標準及國際通用文物保護研究方法與評估準則相結合，通過膠化物形成周期、滲透深度、孔隙度、毛細吸水和滲透系數、持水量、抗壓強度、抗鉆強度、吸附水蒸氣的能力、透氣性、外觀顏色等系列參數的測定，及凍融、冷熱循環、酸堿腐蝕后抗壓強度的衰減、可溶鹽對保護效果的影響、酸堿及光照對表面保護效果的影響，對兩種含氟聚合物及其與有機硅的共混物在文物加固保護和表面防護中的可行性和保護效果給予了系統研究。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。Products and systems for the protection and repair of concrete structures - test methods - determination of loss of mass of hydrophobic impregnated concrete after freeze - thaw salt stress
