Applications of polymer based binder material can be an ideal choice in civil infrastructural applications since the conventional cement production is highly energy intensive. Moreover, it also consumes significant amount of natural resources for the large-scale production in order to meet the global infrastructure developments. On the other hand the usage of cement concrete is on the increase and necessitates looking for an alternative binder to make concrete. Geopolymer based cementitious binder was one of the recent research findings in the emerging technologies.

New state-of-the-art materials designed with the help of geopolymerisation reactions are opening up new applications and procedures and transforming ideas that have been taken for granted in inorganic chemistry. High temperature techniques are no longer necessary to obtain materials which are ceramiclike in their structures and properties.
These materials can polycondense just like organic polymers, at temperatures lower than deg. This new generation of materials, whether used pure, with fillers or reinforced, is already finding applications in all fields of industry. Some examples:. These applications are to be found in the automobile and aerospace industries, non-ferrous foundries and metallurgy, civil engineering, plastics industries, etc.

Geopolymer Binders: A Need for Future Concrete Construction
On 10 Nov In News. Australia, October BWWA was built with approximately 40, m3 , tonnes of geopolymer concrete making it the largest application of this new class of concrete in the world. The geopolymer concrete developed by the company Wagners, known as Earth Friendly Concrete EFC , was found to be well suited for this construction method due to its high flexural tensile strength, low shrinkage and workability characteristics. Heavy duty geopolymer concrete, mm thick, used for the turning node, apron and taxiway aircraft pavements, welcomes a heavy cargo for regular air traffic between Toowoomba-Wellcamp BWWA airport and Hong Kong.. See the video on my visit to the Toowoomba-Wellcamp-Airport.

Joseph Davidovits born 23 March is a French materials scientist known for the invention of geopolymer chemistry. He posited that the blocks of the Great Pyramid are not carved stone but mostly a form of limestone concrete or man-made stone. Davidovits believes that the blocks of the pyramid are not carved stone, but mostly a form of limestone concrete and that they were "cast" as with modern concrete. The limestone was then dissolved in large, Nile-fed pools until it became a watery slurry. Lime found in the ash of cooking fires and natron also used by the Egyptians in mummification were mixed in. The pools were then left to evaporate, leaving behind a moist, clay-like mixture. This wet "concrete" would be carried to the construction site where it would be packed into reusable wooden moulds and in a few days would undergo a chemical reaction similar to the curing of concrete.
