setting retarder
解釋
凝固減速劑-
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。 -
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。 -
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。
