鹼膠凝材料為在鹼激發液的作用下所形成的一種具有膠結性質的材料，其製作方法和所使用的原料均不同於普通的波特蘭水泥。鹼膠凝水泥之硬化機制和所形成的產物，也與波特蘭水泥相異。鹼激發水泥、鹼激發礦渣水泥、鹼激發飛灰水泥以及土壤聚合物水泥都屬於鹼膠凝材料。

　　本文使用爐石粉、飛灰和紅土為基本原料來製作鹼膠凝材料，討論原料的配比對鹼膠凝混凝土物理性質之影響，並利用掃描式電子顯微鏡來觀察所製成的鹼膠凝材料之微觀結構。研究的結果發現爐石粉若存在過量的鹼激發液環境中，則產物中會含有氫氧化鈣；但氫氧化鈣有產生二次反應之趨勢出現。爐石粉在較少的鹼激發液環境中，早期強度發展迅速且不生成氫氧化鈣，但強度在28天以前發生大量衰減的現象。而鹼膠凝材料中，若同時存在鈣矽水化物膠體與土壤聚合物膠體，則材料之微觀結構會更緻密，強度也會提高。

　　Alkali cementitious materials refer to any system that uses an alkali activator to initiate a reaction or a series of reactions that will produce a material that possesses cementitious property. Preparing technique, raw materials, hardened mechanism and hydrate completely differ from those of Portland cement. Alkali activated cement, alkali activated slag and fly ash, and geopolymers are all considered to be alkali cementitious systems.

　　In this study, granulated blast furnace slag, laterite, and fly ash, were investigated as basic ingredient of alkali cementitious materials. Scanning electron microscopy was used to study the effects of batchcs of the raw materials and dosage of the activators on the microstructure and physical properties of alkali cementitious materials. During this work it was found that calcium hydroxide was also formed when slag was activated in a excess alkaline environment. However, calcium hydroxide will further react. When a lower alkalinity was used, the early compressive strengths of slag based alkali cementitious materials reached their highest strength quickly, but rapid loss before 28 days. It is suggested that the coexistence of CSH gel and geopolymeric gel, resulting in increased mechanical strength.
