本研究探討強塑劑於主要水泥成份相及水化產物的吸附行為及與漿體流變行為的關係。試驗將完成水泥早期水化主要成份相C3S、C2S與C4AF之合成。並利用所合成之化合物製作漿體,測量漿體添加強塑劑後之吸附量及漿體流變行為。研究結果發現,水泥漿體水化初期之黏度變化與各化合物的水化作用密切相關,各漿體之黏度在極短的水化時間內即大幅上升。然而,此黏度量測同時受到水化與析離的影響,造成黏度變化大且不與強塑劑劑量間呈明顯關係。就強塑劑的吸附行為而言,以C4AF的單位面積吸附量最高,C2S次之,C3S最低。水化初期三個化合物中又以鋁鐵酸四鈣的黏度發展最快。而使用強塑劑後,添加之強塑劑劑量越高其吸附量越高所對應之黏度值越低,但並非所有試樣都呈現一樣之趨勢,其造成不穩定因素同時存在,合成之試樣本身化性不同,試樣遇水快速水化,漿體之析離影響等,這些因素都會造成試樣吸附強塑劑不完全,進而影響黏度與吸附量。總而言之,整體的研究結果說明強塑劑與水泥各主要成份間的交互作用,未來有助於改善強塑劑的性能,提升與不同種類水泥的相容性。
This study explores the adsorption behavior of the superplasticizer on the major phases of the hydrating cement pastes and their rheological behaviors during the early hydration. During the study, the major phases of the Portland cement, C3S, C2S and C4AF, are synthesized and prepared for the rheological and superplasticizer adsorption measurements. Results showed that the viscosities of the cement pastes during the early hydration were highly associated with the hydration of the major phases in cement. The viscosity of the phases mixed with water increased rapidly during the very early hydration. Such increases were also related with the segregation in the presence of superplasticizer. Both hydration and segregation may be responsible for the uncertain relationship between the paste viscosity and the superplasticizer dosage. Results also showed that the superplasticizer adsorbed the most on C4AF and the least on C3S, estimated by the amount of adsorption per unit surface area. During the early hydration, C4AF had the fastest viscosity increases among the three phases. In the presence of superplasticizer, the viscostity decreased with the increase of adsorption. Nevertheless, such relationship was not consistent in all the mixtures. There are some influencing factors, such as the compositions, hydration rate and segregation. These factors induced the incomplete adsorption of superplasticizer, which in turn affected the viscosity and adsorption capacity.
