  1. Hi this thesis, the setting time of various retarders had been tested, in which three retarders with good retarding action, citric acid, sodium tripolyphosphate, bone glue are respectively chosen from three types of retarders, hydroxyl carboxylic acid type, phosphate type and protein type, and the strength and setting time of gypsum added with them are determined. effect of some factors, such as ph value, fineness of hemihydrate, type of gypsum on the retarding action of the retarders is also studied

    本文對多種緩凝劑進行凝結時間測試，選擇效果良好的羥基羧酸、無機鹽和蛋白質類型的三種緩凝劑：檸檬酸、多聚磷酸鈉和骨膠，測定它們對石膏凝結時間、強度等宏觀性能的影響，並分別研究ph值、石膏細度和石膏種類等因素對它們的緩凝效果的影響。
  2. Gypsum for portland cement retarder

    硅酸鹽水泥緩凝劑用石膏
  3. Results of experiment show that the reason of strength decreasing of gypsum added with retarders is that the retarders reduce the supersaturation of liquid phase, and makes the crystal grain largen, and pore is followed to worsen, which lead to the strength drop to a large degree

    實驗結果分析表明：在摻加緩凝劑后石膏硬化體強度下降的原因在於緩凝劑降低了石膏的液相過飽和度，使結晶顆粒變大，使石膏的孔結構惡化，最終導致了宏觀強度大幅度下降。
  4. The effects of gypsum on fluidity of cement mortar and setting time of cement paste are not significant when it used as retarder of cement. whereas, when 0. 3 % ca - lignosulphonate or ca - solassate added in cement used anhydrite gypsum as retarder, loss of fluidity of cement mortar is rapid, quick setting is occurred

    但是，在硬石膏調凝水泥中摻加0 . 3的木鈣和糖鈣緩凝減水劑卻能使水泥砂漿流動度經時損失加快，凈漿表現出促凝現象，發生外加劑與水泥的不相容問題。
  5. Selection of suitable retarding agent and its addition is particularly important for controlling the setting time of gypsum - based material in a certain rang, meeting the requirement of construction process. though the retarder is widely used, the influence factor, the intrinsic reason that induces the strength drop and retarding mechanism are still studied superficially

    盡管石膏緩凝劑的用途廣泛，但是對於它的影響因素、緩凝劑強度降低的內在原因和緩凝劑阻礙石膏水化形成緩凝作用的機理的研究粗淺，認識模糊。
  6. Furthermore, by testing the supersaturation of liquid phase, hydration rate, hydration temperature as hydration of gypsum with the retarders, the effect of retarders on the hydration process is found out

    通過對摻加緩凝劑后對石膏水化過程中的液相過飽和度、水化率和水化溫度的測試，了解緩凝劑對石膏水化進程的影響。
  7. As a kind of cement retarder, normal setting time and good effect for mechanical properties and soundness of cement can be got when adding desulfurization gypsum in cement, so it can used instead of natural gypsum to produce cement entirely, coal gangue is activated and coal ash desulfurized have good active, can improve cement output and also can depress consumption when them be used as mixed material, have well economic and environmental effects

    脫硫石膏作水泥緩凝劑時，水泥的安定性、凝結時間正常，可改善水泥的力學性能，完全可替代天然石膏；活化后的煤矸石和脫硫煤灰具有較好的活性，用作水泥混合材可增加水泥產量、降低生產成本，具有良好的經濟和環境效益。
  8. The scanning electron micrographs and the data of pore structure of gypsum and gypsum with the retarders also make us known the influence of retarders on the crystal morphology and pore structure, from which transformation of microstructure induced by retarders and the reason of which makes the strength drop a re analyzed. combined with the xps spectrum, the mechanism of action with the retarders are finally proposed

    繼而通過對孔結構和石膏硬化體晶體掃描電鏡照片的觀測，獲得緩凝劑對石膏硬化體晶體形貌的影響和對孔結構的改變的信息，分析緩凝劑的帶來石膏的微結構的變化，以及摻加緩凝劑帶來石膏強度下降的原因所在。
  9. The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper. the experimental results indicate that the effect of single retarder, such as citric acid, is inferior to that of composite retarder which was made of blending citric acid with a few portland cement ( about 0. 5 ?, by weight ). the effect of different water - retention agents, such as polyvinyl alcohol ( pva ), carboxymethyl cellulose ( cmc ), and na - bentonite, etc., was also studied, and the results demonstrate that by means of adding organic and inorganic water - retention agent simultaneously the water - retention of plastering slurry can obviously be improved. the optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other

    研究了分別以檸檬酸、檸檬酸與普通硅酸鹽水泥復合物作緩凝劑，調節粉刷石膏的凝結時間，並對比2種緩凝體系對石膏抗折、抗壓強度的影響.比較不同保水劑（聚乙烯醇、羧甲基纖維素）以及相同量的保水劑在不同工藝流程下保水效果上的區別.探索了有機保水劑和無機保水劑對粉刷石膏的保水性的影響.結果表明，檸檬酸與普通硅酸鹽水泥的復合緩凝劑比單純的檸檬酸更能有效地延緩建築石膏的凝結，同時建築石膏的抗折、抗壓強度降低幅度減小
