水分子集團減縮處理對水泥砂漿性能影響之探討 The Influence on Characteristics of Mortar by Reducing the Cluster of Water Molecule 許 桂 銘 Kuei-Ming Hsu 高苑技術學院土木工程技術系 Department of Civil Engineering Kao Yaun Institute of Technology 摘 要 使用水分子集團減縮技術如逆滲透、微波、遠紅外線、電解與磁化等 處理拌合用水，可有效減少水分子之集團數。本文使用Ottawa砂與自來水 為基準，在標準流度條件下之用水量，分別量測各種經水分子集團減縮處 理拌合用水之水泥砂漿流度、抗壓強度、吸水率與波傳速度等性能。另外， 亦探討高飛灰摻用率(40%F 級飛灰)與不同砂源(里港砂)之性能影響。由實 驗結果顯示，使用經減縮處理後之拌合水，有促進中晚期水化之效果，包 括強度與波速增加，吸水率減少，且與水分子集團數成反比，流度則無顯 著變化。減縮處理後之拌合水，對高飛灰摻用率之水泥砂漿亦有促進水化 之效果。至於不同砂源(里港砂)，趨勢亦類似。各種水分子集團減縮處理 中，晚期抗壓強度(28天與90天)增加率依序為磁化、電解、逆滲透、微波 與遠紅外線，其中，磁化處理在適當磁化參數下，可增加16～19％，且經 濟性高，值得進一步探討與發展 。 關鍵詞: 水分子、減縮處理、水化、飛灰、磁化 ABSTRACT The technology of reducing the cluster of water molecule same as reverse osmosis, micro wave, Infrared ray, electrolysis and magnetization can effectively reduce the numbers of cluster of water molecule. This article use the materials of Ottawa sand and potable tap water to make an experiment. Under the condition of standard flow of the moisture to measure the varied characteristics that it had been reducing the cluster of water molecule mixing water of mortar flow, compressive strength , absorption and velocity of wave respectively. Besides, it is researching the influence of high rate of replacing fly ash (40%F grade fly ash) and varied sand (Lekang sand). The result of 1 experiment shows that the mixing water used the reducing the cluster of water molecule promoting the hydrating affection of middle-late period, including the increasing of strength and velocity of wave and decreasing the absorption . Also, it is inverted to th
