  1. Under the different freezing - thawing cycle circumstance, three factors of water binder ratio, air content and mineral admixture are analyzed by using the method of orthogonal table. the test results show that the chief influencing factor is the water binder ratio in water freezing - thawing cycle circumstance, and in salt freezing - thawing cycle circumstance is the air content. this could illustrate that entraining air into concrete can improve the frost resistance of concrete effectively in salt freezing - thawing cycle

    分析了在純水和3 . 5 % nacl溶中受凍后,水比、含氣量和摻合料對混凝土飽和系數及變速率的影響規律,結果表比對混凝土水凍時的飽和系數及變速率影響顯著,而鹽凍情況下含氣量則是主要影響因素,說引氣能顯著提高混凝土的抗鹽凍性能。
  2. 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:通過對rpc各組分摻量變的研究,可以找到rpc的最優配合比;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,可以發現rpc的凝體中ch晶體已經幾乎不存在,凝體主要由c - s - h凝和未水水泥顆粒組成;在抗溶侵蝕的實中,摻礦渣rpc的抗溶侵蝕性能在絕大多數情況下要好於不摻礦渣件,酸、堿溶和浙江工業大學碩士學位論文摘要一些鹽溶都會對rpc的結構產生侵蝕作用,但是機理各有不同。
  3. With the reference of many relevant materials, the author prepared a fined molybdenum disulfide powder with a average size of 800nm by ball milling, and a nano - copper with average size of 30nm in micromulsion solution method, and synthesized surface - modified titanium dioxide nanoparticles with average size of 40nm in organic media via sol - gel method. the tribological performances of three particles were studied by universal test as well, with the result of fined molybdenum disulfide powder with good reducing wear and antiwear performance at low load, nano - copper with good reducing wear and antiwear performance at high load, surface - modified titanium dioxide nanoparticles maintaining stable reducing wear and antiwear performance from low load to high load due to its characteristics of organic and inorganic nanocomposite. the results indicate that the nanocomposite is the most perspective oil additive. the reducing wear and antiwear mechanism of nano oil additive was studied with in - situ tribochemical principle. nano additives possess broadly developing prospect with its above - mentioned performance

    在參閱了大量文獻的基礎上,分別採用了球磨法、微乳法、溶?凝法制備了超細二硫鉬、納米銅粒子、表面修飾納米二氧鈦,經原子力顯微鏡測,獲得的超細二硫鉬的粒度平均在800nm以內,納米銅粒子平均粒度約為30nm ,表面修飾納米二氧鈦平均粒度約為40nm ,在萬能摩擦磨損機上測了三種粒子的摩擦學特性,結果表:在合理的添加濃度范圍內,超細二硫鉬在低載時具有優良的減摩抗磨性能,納米銅在高載時具有比較好的減摩抗磨性能,表面修飾二氧鈦粒子因具有有機與無機復合物的特性,從低載到高載都保持穩定的減摩抗磨性能。
