本研究主要希望透過磁場直接施加於膠結材料-水泥，研判水泥試體經過磁場磁化後是否能改變其微觀結構及抗壓強度等物理性質。由於磁化水應於混凝土製成已有一定的成果，綜合文獻所述，磁化水拌置混凝土製品都有強度提升的優良反應，故本研究希望磁場施加於水泥漿體，其結果也有不錯的反應。研究方法主要是將新拌製之水泥漿體，尺寸2.5立方公分之試體，放入0.17T的磁場環境內進行養護，並於齡期7天、14天、28天、56天，將磁化養護試體與一般養護試體進行抗壓試驗及微觀結構觀測(SEM)，在將獲得之結果加以分析比較。研究結果顯示，水泥在磁場強度0.17T之環境養護時，(1)磁化28天及56天之試體比一般試體抗壓強度降低9%-13% (2)水泥之水化產物並不會受0.17T之磁場環境，而改變其生長方向 (3) 根據SEM結果顯示，磁化28天及56天試體之水化產物CH晶體，比一般試體來的多。

In this study, magnetic field is directly applied to cement to observe the physical properties, such as microstructure and compressive strength, of cement specimens magnetized via the magnetic field. The magnetic field with an intensity of 0.17 T applied to the fresh cement paste of a 2.5 cm3 size. The compression test and microstructure observation were performed for the magnetically cured and normally cured specimens after curing for 7, 14, 28, and 56 days. The results of the study show that when the cement was cured using the magnetic field, (1) the compressive strength of the specimens magnetized for 28 and 56 days was 9%–13% lower than that of the normally cured specimens, (2) the hydration products of the cement did not show their growth direction following the magnetic path in this study, and (3) according to the SEM results, the quantities of CH crystals in the hydration products of the specimens magnetized for 28 and 56 days were more than those in the normally cured specimens.
