將菟絲子乾粉用75乙醇浸泡后,減壓蒸干后得到褐色漿狀物,經石油醚、氯仿、乙酸乙酯、正丁醇萃取,經柱層析后,再用葡聚糖凝膠對有效成份進一步純化,獲得了菟絲子中能誘導pc12細胞分化的活性組分。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 order to study the direct relation between oil - base drilling fluid performance and cement job quality, a new developed evaluation method ( artificial core method ) was adopted ; the effects of the oil - base drilling fluid system and its main components on the shear cementing strengths of the first and second interfaces in cementing operation were investigated ; and those of the different mix slurry ratios on the gel strength, initial set time, final set time of slurry and the compressive strength of bond cement were examined too
摘要為了研究油基鉆井液性能和固井質量之間的直接關系,採用新建立的評價方法人工巖心法,考察了油基鉆井液體系及其主要組分對固井作業中第一、第二界面剪切膠結強度的影響規律,以及不同混漿比例下對水泥漿膠凝強度、初凝時間、終凝時間和水泥石抗壓強度的影響規律。Abstract : based on composite testing of naphthalene superplasticizer and different retarders as well as retarding water reducer, in which the overall amount of admixture is certain, this paper analyzes the influence of these multicomponent admixtures on flowability of neat cement 、 retarding action and development of strength of colloidal mortar. the result shows that compatibilities of different components are different, and composition effects are also different
文摘:在總摻量一定的情況下,就萘磺酸鹽高效減水劑與不同緩凝組分、緩凝型減水劑等復合后對水泥凈漿流動度、緩凝作用、膠砂強度發展等性能的影響作用進行了試驗分析,結果表明各不同組份復合的相容性不同,復合效應也存在差別。Based on the calculation methods of nominal water - cement ratio of mortar and average paste thickness of standard sand provided by authors, the nonlinear relation between fluidity of mortar and nominal water - cement ratio of mortar, average paste thickness of standard sand, fly ash - binder ratio was established by using artificial neural network ( ann )
摘要在給出水泥膠砂名義水灰比和標準砂平均漿體厚度計算方法的基礎上,採用人工神經網路方法,建立了水泥膠砂流動度與水泥膠砂名義水灰比、標準砂平均漿體厚度、粉煤灰與膠凝材料用量比之間的非線性映射關系。Under the conditions of high efficiency water - reducing agent, the homogenization of starch mixed composite powder is better than that of blank cement and only mixed fly ash
在高效減水劑存在的情況下,摻復合粉的膠凝材料漿體勻質性優于空白水泥與單摻粉煤灰。Use the principle of material complex, carboxylic styrene - butadiene rubber latex added to the ordinary mortar forms pmm which takes the place of the conventional mortar as the surface coated. it can improve the cracking - proof feature, permeability, flexibility, as well as the compatibility with formwork concrete, to protect the formwork from corrosion and finally to enhance the durability of formwork concrete
利用材料復合的原理在普通砂漿中摻入丁苯膠乳形成聚合物改性水泥砂漿代替傳統的普通水泥砂漿作為模網混凝土的表面保護層,以改善面層砂漿的抗裂性、抗滲性、柔韌性,提高其與模網混凝土的協調變形能力,從而保護內部鋼模網不受銹蝕並最終提高模網混凝土的耐久性。分享友人
