Geopolymer Cement-Based Composite as Self-Cleaning Coating
Geopolymer is the combination of the pozzolanic compound, which is also known as aluminosilicate source materials with an alkaline activator solution. The concept of green blending materials has led to the development of a new binding material for green materials, which is geopolymer with an addition of photocatalyst. Moreover, concepts of self-cleaning have received great attention in construction building materials. Self-cleaning with the presence of photocatalyst has been applied in building materials to overcome the problem of building surfaces becoming dirty after exposure for a long time in highly polluted areas.

Geopolymer Composites Designed for Water and Wastewater Treatment
Since the discovery of geopolymers four decades ago, they have come quite a long way successfully and gained attention, mostly due to the effortlessness for geo-synthesis with lesser emission of greenhouse gases (GHG). Their admirable properties, such as toughness, heat and fire resistance, refractory nature and radiation hardness, altogether make them promising for applications for radioactive waste containment, as well as for pozzolanic action, making them multi-functional. In realism, lots of industrial materials are derived using geopolymers. For example, fiber-based geopolymer composites are regarded as fire-resistant. Quite a lot of geopolymeric composites are positioned in metal tool coatings and the construction of cabinets of airplanes and buildings, with a view to trim down the intensity of inferno incidents. The polymeric chain-like structure of geopolymers contributes higher chemical resistance, lower shrinkage and enhanced resistance to abrasion with high early mechanical strength. This entry describes that applications and interaction of geopolymer.

Geopolymer Concrete (GPC)
Geopolymer concrete (GPC) is a new material in the construction industry, with different chemical compositions and reactions involved in a binding material. The pozzolanic materials (industrial waste like fly ash, ground granulated blast furnace slag (GGBFS), and rice husk ash), which contain high silica and alumina, work as binding materials in the mix. The sustainable development can be achieved by employing geopolymers in construction industries, because it results in lower CO2 emissions, optimum utilization of natural resources, utilization of waste materials, low energy consumption, thermally stability, more cost-effective in long life infrastructure construction, and, socially, financial benefits and employment generation

Geopolymer Materials for Bone Tissue Applications
Geopolymers (alkali-activated materials) are amorphous inorganic polymeric systems with aluminosilicate bases produced by alkalinising natural or waste substances, such as metallurgical, industrial, urban, and agricultural wastes. There is increasing academic interest in geopolymer materials for biomedical applications.

Geopolymers
Geopolymers represent novel material types at the interface of glass, ceramics, and materials based on traditional inorganic bonds. Geopolymers utilize waste materials as source material and activate the materials with alkaline activators to act as binders. Metakaolin is categorised as an aluminosilicate material because it contains variable amounts of alumina and silica. Geopolymers offer benefits due to their ease of synthesis and low emissions of greenhouse gases such as CO2, SO2, and NOx.

Geopolymers as Construction Materials
Utilising geopolymer as a construction material has gained institutional and commercial interest over the past decade, due to its favourable emissions profile as an alternative to carbon-intensive Ordinary Portland Cement-based concrete, which currently accounts for around 7% of global carbon emissions.
