摘要

研究水泥熟料鑛物的歷史已久，而將研究成果應用於工業生產則是近年來的事，若利用尖端科技使鑛物鑑定以數值表示並输入電腦，以做為製造的指針，乃數年前才由先進國家首創。將水泥熟料的主構成鑛物阿來石（alite）與貝來石（belite）的特性與燒成過程加以簡化，以（1）燒成速率（burning rate）、（2）最高溫度（maximum temperature）、（3）高溫燒成時間（burning time）及（4）冷却速率（cooling rate）四個條件連結起來。這四個條件與（1）阿來石之粒徑（alite size）、（2）阿來石之複折率（alite birefringence）、（3）貝來石之粒徑（belite size）及（4）貝來石之顏色（belite color）四個項目相結合，再由此四項目來推定該熟料磨成之水泥之28天強度。臺灣水泥工業雖亦有公司試用此方法，惟因缺乏鑛物學的科技知識，似未見有很大的發展。本文擬以臺灣水泥工業生產的水泥試料為基礎研究的實例並加以解釋。

Although the analysis of the mineral composition of cement clinker has been subject for extensive study for many years, only until recent years the improvement in industrial production of cement from the application of the results of research has been achieved. Very recently, a technique of using the mineral constituents in the form of digital data via computer processing as a manufactuning index has been established for the first time by the technology-developed counries. The characteristics of alite and belite, the major mineral constituents of cement clinker, are controlled by (1) burning rate, (2) maximum temperature, (3) burning time at maximum temperature and (4) cooling rate in the cement manufacturing process. These four parameters are characterized with (1) partcle size of alite, (2) birefringence of alite, (3) particle size of belite and (4) the color of belite. The above information will then be used in predicting the cement strength after 28-day curing. The fundamental research has been carried out in the area of this newly-developed technique with the use of cement produced in Taiwan. Interpretations for case examples will be presented in the hope that this will be echoed by both academic and industrial communities.
