**5. Reinforcement in Kaolin Ceramic Geopolymers**

In comparison to OPC-based materials, geopolymers exhibited improved mechanical characteristics and resilience to fire, sulphates, and acids. When used as OPC products, geopolymers, however, exhibit brittle failure due to low tensile strength, which may place several restrictions on its potential structural uses. Usually the material properties of kaolin ceramic geopolymers have a greater impact on the performance of reinforced geopolymer composite than binders do. Table 8 summarises the various types of additions, the percentages of additions, and the results of studies that examined the enhancement of properties in kaolin geopolymer ceramic.
