Alkali activated materials (AAM) are produced by a chemical reaction between solid raw materials and alkaline solution. The strength, as the most important mechanical property, is commonly used as a basic measure of usability of different raw materials in the production of AAM.
Raw materials differ markedly in physical, chemical and mineralogical properties. Most common types of raw materials used for AAM production are calcined materials, such as metallurgical slags, thermally activated (calcined) clays, and fly ashes based on the coal combustion. Calcined materials are mostly amorphous since the calcination process activates materials by changing their crystalline structure into amorphous one. Non-calcined raw materials, such as kaolinite, mine tailings and naturally occurring minerals, are also used.
During the alkali activation process, the vitreous phase of raw materials dissolves, forming calciumsilicate or aluminosilicate gel afterwards. This reaction depends on a whole seri...es of parameters such as: raw materials particle size distribution, amount and chemical composition of vitreous phase, as well as the activator type, concentration, and pH of the activator solution. Conditions of the reaction of alkali activation, such as temperature, time and relative humidity, also have a great impact on the microstructure development, and thereafter on the strength of AAM.
