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。Chemical industry information not merely embodyed the ordinary chemistry information substance, chemistry manufacture technological process and representative installation introduction are still have, in case contacing legal institutions sulphuric acid ? nitric acid industry system law ( ammonia oxidate law ), synthetic ammonia industry, chlorine and caustic soda are manufacture to electrolysis salt water, along with electrogilding, refine aluminium, iron - smelting and steel - smelting, cement and glass manufacture summarized account, the mineral oil is refined, hence, the chemical industry information education is contrastd against the ordinary chemistry information education, proper such representative means, be living, the means interpreted is in speech oridinarily wholly adoptd in the chemical industry information education, now most of tutors also is adopt the means interpreted in speech, cause that the chemical industry information education is insipid like this, student lack interest to chemical industry information study, but as a result of value the pair foundation, light practice, student may say the become a mere formality to chemical industry information study o since multi - med
化工知識不僅包含了一般化學知識的內容,還帶有化學生產工藝流程及典型設備的介紹,如接觸法制硫酸,硝酸的工業製法(氨氧化法) ,合成氨工業,電解食鹽水製造氯氣和燒堿,以及電鍍、煉鋁、煉鐵和煉鋼,水泥和玻璃的生產簡介,石油的煉制等,因此,化工知識教學與一般化學知識教學相比,應有其典型的方法。在過去,化工知識的教學一般都採用口頭講解的方法,現在大多數教師也是採用口頭講解的方法,這樣使得化工知識的教學乏味,學生對化工知識的學習缺乏興趣,又因重視雙基,輕實踐,學生對化工知識的學習可以說流於形式。由於多媒體的輔助教學的高效性、形象直觀性、新穎性和多樣性、人工模擬等特點,很適合化工知識的教學,應用多媒體教學化工知識可以解決目前存在的諸多問題,如:模型短缺、組織參觀活動困難、教育經費不足、學生不易觀察等。With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明:通過對rpc各組分摻量變化的研究,可以找到rpc的最優配合比;試件成型后的熱養護制度對rpc的性能影響巨大; rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況,剛纖維的摻入可以大幅改善rpc的韌性; rpc在成型后存在較大的收縮,而其中的化學收縮要遠遠大於乾燥收縮; rpc具有很強的抗氯離子滲透性能,漿體的密實度很高;通過x射線衍射實驗,可以發現rpc的膠凝體中ch晶體已經幾乎不存在,膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成;在抗溶液侵蝕的實驗中,摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件,酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用,但是機理各有不同。In light of various pollution situations and various water treatment processes of two water factories, better solved the problems about throwing doses, throwing localities, throwing forms of composite potassium permanganate and powder activated carbon, as well as compared the enhanced coagulation efficacy of combined process of composite potassium permanganate and powder activated carbon, composite potassium permanganate pre - oxidation and pre - chlorination
