· Introduction. Geopolymers, as inorganic polymer materials, are also known as alkali-activated materials (AAMs). Geopolymers can take natural materials and waste products as the primary raw materials synthesized by alkali or acid activation reaction. Common raw materials and their abbreviations are shown in Table 1.
