100,000 tonnes Geopolymer Concrete: world premiere

Toowoomba, Brisbane West Wellcamp airport, Australia #Wellcamp747

Australia, October 2015.Brisbane West Wellcamp Airport (BWWA), Toowoomba, Queensland, is Australia’s first greenfield public airport to be built in 48 years. BWWA became fully operational with commercial flights operated by Qantas Link in November 2014.

30 years after my invention of Geopolymer cement in USA, at Lone Star Industries (Pyrament cement), this project marks a very significant milestone in engineering – the world’s largest geopolymer concrete project, so far. BWWA was built with approximately 40,000 m3 (100,000 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, 435 mm thick, used for the turning node, apron and taxiway aircraft pavements, welcomes a heavy 747 cargo for regular air traffic between Toowoomba-Wellcamp BWWA airport and Hong Kong..(See the video on my visit to the Toowoomba-Wellcamp-Airport).

Wrong statement on Pyramids of Bosnia

I wrote in my main article dedicated to the Bosnian Pyramids an update stating that: « According to our information, we believe that the sample of concrete that I have examined under the electron microscope comes from a type of cistern or water tank (the drilling report is mentioning a concrete « ceiling » and an empty space of 4 meters depth followed by a « concrete » floor, see the pdf below). The geopolymer concrete analyzed is a kind of Roman concrete, which in no way corresponds to the materials that constitute the casing of the pyramids and look like pudding stone. Consequently, the information published on the Bosnian Pyramids websites are inaccurate. » Read the entire article at Pyramids in Bosnia.

Paleomagnetism study supports Pyramid man-made stone

A recent scientific study published in the renown “Europhysics News“, The Magazine of the European Physical Society, (2012), Vol. 43, number 6, described how paleomagnetism study on several pyramid stones demonstrates the validity of Davidovits’ theory on the artificial nature of Egyptian pyramid stones.
Two scientists, Dr. Igor Túnyi from Geophysical Institute SAS – Bratislava (Slovak Republic) and Ibrahim A. El-hemaly from National Research Institute of Astronomy and Geophysics – Cairo, Egypt, made the following assumption (quote from their scientific paper):
