  • 本論文主要目的為製備一種兩性離子型的吸水性水膠,使用丙烯醯胺、disodium 1-(4-(3-((carboxylatomethyl)dimethylammonio) propylamino)-4-oxobut-2-enoate)( 1-(4-(3-(((羧甲基)二甲基銨)丙基氨基)-4-氧代丁-2-烯酸酯)二鈉)) (CDP)和矽灰為單體,合成 SF/PCA,使用FT-IR作結構鑑定,探討單體比例、起始劑或交聯劑劑量和矽灰含量對於水膠在各種水溶液下吸水率的影響。
    將SF/PCA水膠加到混凝土和水泥砂漿中,作為自養護劑時,探討單體比例和矽灰比例含量,對於水泥漿中對於水泥砂漿和混凝土抗壓強度、內部濕度、乾縮量和自體收縮量的影響。
    實驗結果顯示, SF/PCA水膠,當AM/CDP= 4, APS= 0.7 mole%, MBA= 0.5 mole%, SF = 10 wt%時,在去離子水中、Pore solution和水泥漿濾液中的最大吸水率分別為480.3 g/g、130.3 g/g、81.3 g/g。
    將SF/PCA水膠加入水泥砂漿和混凝土中,當水膠劑量為0.2 wt% 和矽灰含量為10 wt%時,對水泥砂漿和混凝土的抗壓強度和內部濕度增加、乾縮量和自體收縮量減少,有較佳的提升效果。

    This thesis prepared a silica fume/amphoteric hydrogel composite SF/PCA as a concrete self-curing agent, is synthesized by acrylamide, disodium 1-(4-(3-((carboxylatomethyl)dimethylammonio) propylamino)-4-oxobut-2-enoate) (CDP) and Silica fume as monomer.FT-IR was used to identify the functional groups of the hydrogel. The effects of monomer ratio, initiator and crosslinker dosage, and silica fume content on the water absorbency of the resulted hydrogel in various aqueous solutions were studied and discussed.
    SF/PCA hydrogel was added into mortar and cement. The effects of monomer ratio and silica fume content on the compressive strength, internal humidity, drying shrinkage and autogenous shrinkage in mortars and cements.
    The results indicated that the highest water absorbency of all tested SF/PCA hydrogel were 480.3 g/g in water, 130.3 g/g in Pore solution,and 81.3 g/g in Cement slurry filtrate repectively, when SF/PCA = 4, APS = 0.7 mole%, MBA = 0.5 mole%, SF = 10 wt%. SF/PCA hydrogel with 0.2 wt% dosage and 10 wt% silica fume showed better performance in cementitious materials. Namely, this polymer could decrease the drying shrinkage and autogenous shrinkage, and increase the compressive strength and internal humidity in mortars and cements.
