Geopolymer cement, high-alkali (K-Ca)-Poly(sialate-siloxo) cement, results from an inorganic polycondensation reaction, a so-called geopolymerisation yielding three dimensional zeolitic frameworks. High-tech Geopolymer K-Poly(sialate-siloxo) binders, whether used pure, with fillers or reinforced, are already finding applications in all fields of industry. These applications are to be found in the automobile and aeronautic industries, non-ferrous foundries and metallurgy, civil engineering… 
Clay-Based Materials in Geopolymer Technology
The term “geopolymer” was introduced by Davidovits in the 1970s. The prefix “geo” was selected to symbolize the constitutive relationship of the binders to geological materials, natural stone and/or

Ordinary Portland cement is an important material used in production of concrete. However manufacturing of OPC has many disadvantages such as depletion of raw materials like lime stone and the clay.
Durability of geopolymer mortars using agro-industrial waste
Geopolymer is a binding material produced from the reaction of silica and alumina (in a source material of geological origin or in by-product material), with alkaline solutions. The use of geopolymer
Preparation of Cement Clinker from Geopolymer-Based Wastes
The results demonstrate that geopolymer binder and mortar materials are suitable substitutes for natural mineral clay incement clinker preparation.
Review of Geopolymer Materials for Thermal Insulating Applications
Geopolymer is an environmentally cementitious binder that does not require the existence of ordinary Portland cement (OPC). Geopolymer has many excellent advantages, including high early strength,
Andreasen Particle Packing Method on the Development of Geopolymer Concrete for Civil Engineering
AbstractAlkali-activated binders (AAB) or geopolymers are new ceramic materials with the potential to replace portland cement in a wide range of applications, from immobilization of heavy metals to
Properties And Microstructural Characteristics Of Geopolymers Using Fly Ash With Different Percentages Of Kaolin At Room Temperature Curing
Geopolymers are inorganic polymeric materials. Geopolymerization involves a chemical reaction between alumino-silicate oxides and alkali metal silicate solutions under highly alkaline conditions. The
Thermomechanical evaluation of geopolymeric and conventional concretes
Geopolymers are a class of inorganic synthetic materials that in recent years have received extensive interest of the scientific community, mainly due to the variety of applications in which they can
Ambient Cured Alkali Activated Flyash Masonry Units
Geopolymers belong to a category of non-conventional and non-Portland cement based cementitious binders which are produced using industrial by products like fly ash and ground granulated blast
