磁磚工程良窳因素很多，其中因黏著效能不佳而導致剝落的現象，更是關鍵因素所在，然而國內對黏著材料之配比，甚少有相關之規定及研究。本論文擬採市售之磁磚黏著材料中最常使用到的三種配比材料，即海菜粉、水泥及水，以模擬工地現場之施工方式，製作各種不同配比試體，進行黏著強度試驗，將所得結果進行比較分析，藉以判斷出最佳的配比範圍，以利作為日後磁磚工程現場施作上的配比依據。而由試驗結果可知，在水：水泥：海菜粉＝70：180：1時，可得最大黏著強度，為最佳配比試驗值，且黏著料亦有良好之工作性。水灰比(W/C）在0.353以下時，黏著料太乾而有施工不易之現象發生，黏貼時效(open time)亦太短，且因黏度不足，黏著強度反而較小

The quality of tile engineering is influenced by many factors. The major factor that tiles peel off is the bad viscidity. Few requlations and researches discuss the mixture of tile adhesives. In the study, there are three most frequently used materials of the adhesives. They are cellulose ether, cement and water. The site methods are used to manufacture the adhesives of the different mixtures to perform the bond strength test. By comparing the results of the bond strength test, we could determine the range of the best mixture, and then it could apply for the reference of the site mixture.
From the results of this present thesis. We have the best bond strength and the better wor kability when the mixture is water : cement : cellulose ether = 70:180:1. Bond strength and workability is bad when the water to cement ratio is smaller
than 0.35 since the open time is too short.keywords : tile emgineering, adhesive,mixture design, cellulose ether,bond strength, open time.
