The result shows, for this composite cement system, retarding action of dihydrate gypsum is more obvious than that of anhydrite, meanwhile, anhydrite tends to cause setting time short and water needed increased
結果表明：二水石膏對該種復合體系水泥的緩凝作用比硬石膏明顯，硬石膏易引起復合體系水泥急凝和需水量增大。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。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。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。分享友人
