In this video, Cole Sonafrank, assistance director of research ay CCHRC, explains basic ingredients for geopolymer cements and the importance of using locally available materials in Alaska. Geopolymer cements use waste materials as a binder and are stronger and more sustainable than conventional Portland cements. CCHRC has studied more than 600 recipes of geopolymers made with use fly ash, a byproduct of coal combustion, from local power plants.

One very promising material is geopolymer cement. It completely replaces Portland cement with waste industrial products. It can also be much stronger and perform better than traditional concrete. In this video, we’re going to discover how geopolymers are made, how they are used, their advantages and disadvantages.

These waste products are difficult to dispose of and they can affect the environment if left untreated. So, using them to significantly reduce the carbon footprint of concrete is an excellent idea. Let’s take a look at some of these waste or low energy materials. - Fly ash or pulverized fuel ash or PFA which is a fine, powdery residue from coal burning power plants. It is mainly composed of silicon dioxide, aluminum oxide and calcium oxide. - Metakaolin which is produced when china clay or kaolin is heated to 1500 degrees Fahrenheit or 800 degrees Celsius. It can be used to make tiles and traditional concrete. - Ground granulated blast furnace slag or GGBS which is a by-product of the steel industry. It is high in calcium silicate hydrates CSH which improves the strength, durability and appearance of concrete. - Palm oil fuel ash or POFA which is produced by burning palm oil shells and husks. It is a hazardous material that is usually sent to landfills, but it can be used to make cement. Advantages - Geopolymers are apparently stronger in tension and compression. - They are resistant to various alkalis, salts, acids and corrosive substances. They also have a high sulfur resistance due to the lack of сalcium compounds in its structure. - Geopolymers have excellent waterproof properties. Its pores are smaller than 50 nanometers so big molecules like water can’t enter in the geopolymer matrix - It is also fire resistant. Unlike Portland cement, water in geopolymer concrete evaporates and does not explode the concrete from inside. - Foamed geopolymer concrete can also have superior thermal insulation thanks to the trapped air inside the blocks. - They can reduce the carbon footprint of concrete by up to 90%. For every 1 ton of Portland cement made, around 0.9 tons of CO2 is released. Conversely, for every 1 ton of geopolymer cement made, only 0.2 tons of CO2 is released. - Geopolymers will help us stop mining and extracting raw materials from the earth because we can use waste and by-products of existing industries. - It can speed up construction because it develops about 50% of its strength in the first 3 days. Disadvantages - There isn’t enough waste material to meet the demand for cement. The global consumption of cement is about 4 to 5 times the generation of industrial wastes like fly ash and slag. - Another issue is the lack of standard and uniform waste materials. For example, fly ash will have a different alumina-silica ratio than slag, so their geopolymer cement mixes will perform differently. - They are difficult to make because the geo-polymerization process is sensitive. Chemicals like sodium hydroxide are harmful to humans so the process requires special handling. - And finally, the biggest drawback in my opinion is that they are up against powerful Portland cement manufacturers, some of whom have a monopoly in the concrete industry. They have control over code requirements and marketing which allows them to easily suppress competition.

Situated next to Cusco in the Inca heartland of Peru, Sacsayhuaman is one of the most incredible ancient structures in the world. It’s truly mind-boggling how such enormous blocks of stones can be so randomly shaped yet so perfectly put together. The origins of the megalithic blocks of Sacsayhuaman, Peru, have long been a source of debate because it really feels like a genuine mystery. These are large blocks of limestone, sometimes huge, most of which seem to pillow or bulge out instead of having straight, sharp cut faces. Some blocks seem to curve around corners, others have scoop marks on the surface and a number have the famous nubs. There are many other seemingly bizarre and unnatural features. Each block is irregular and each is unique yet the joints between these limestone blocks are perfect. So how is this even possible? I’ve speculated in the past that maybe some kind of stone softening agent was applied, possibly some kind of acid. At the end of the day, we can stare at pictures and speculate forever; what we have to do is look at the science. I’ve always said that samples need to be taken and the geology needs to be analysed and that will tell us everything we need to know about Sacsayhuaman. Well, little did I know that such investigative work was done back in 2012 and in this study and take a detailed look at the geology of the blocks of Sacsayhuaman and so, once and for all, we should be able to answer the question - are they artificial geopolymer or natural rocks?

Here at Geopolymer Solutions, we are furthering our efforts to make positive environmental changes globally. Using industrial waste/by-products to develop workable, more robust, and longer-lasting products is part of our corporate DNA. Bauxite residue, red mud, is a hazardous by-product of the Bayer process, refining bauxite to produce alumina. According to experts, aluminum mining creates over 100 million metric tons of this toxic waste per year. The aluminum industry has long tried to find a safe and economical solution with little success. Here at Geopolymer Solutions, we use leading-edge technology to tackle the global red mud situation and turn waste into valuable products within the construction industry. 🤍 🤍

The TU Delft team is working on a sustainable type of concrete made from waste products: geopolymer concrete. Subscribe to our channel here: 🤍 The production of concrete has a large impact on our environment: it is the second largest producer of CO2, and is responsible for emitting up to 5% of global CO2 emissions, contributing to climate change. This is not the only problem we're facing in our modern world: the waste production in many other industries is growing, and means our landfills are quickly filling up and valuable resources get lost. At the Faculty of Civil Engineering, the geopolymer team is researching a type of concrete that uses waste and by products instead of cement as a raw material. This material is called geopolymer concrete, and is made by mixing different industrial byproducts. The hardened concrete has comparable or even better properties than traditional concrete. Already the theory has been put into practice: a geoconcrete canoe has been built, a cantilevered bench, and a bridge is up next. The role of waste is thus rethought and industrial byproducts can be given a new life, reducing CO2 emissions and making landfills smaller. Geopolymer concrete might just be the building material of the future. Faculty of Civil Engineering & Geosciences. Interested in the material and want to seen another cool project?

Subtitles available (English, French and Castillan) Video en Castillan aquí: 🤍 At the 10th Geopolymer Camp in 2018, Prof. Joseph Davidovits presented during his annual keynote his last studies on the Tiwanaku / Pumapunku Megaliths. In November 2017, an international team (a geologist from Universidad San Pablo at Arequipa, Peru and a member of the Geopolymer Institute) went on the site to carry on a survey on these stones. After different analysis on thin sections and under the electronic microscope, Joseph Davidovits claims that he has found "organic matter in volcanic rock", which is, by nature, impossible.

Concrete is the second most commonly used material on our planet after water, and also the second biggest producer of CO2 emissions. This year alone over 3.2 billion tons of CO2 will be released into our planet’s atmosphere, equivalent to the emissions from every car in Europe, America and China. For over 3,000 years we have been producing concrete by the same primitive method of the heating and grinding of limestone. Humanity is now on the brink of a Fourth Industrial Revolution, where technological advances are providing Architects, Engineers and Material Scientists with the tools to produce the next generation of high-performance, low-impact materials. Materials such as geopolymer concrete, a low-carbon, zero-waste, circular economy model to protect finite natural resources, reduce CO2 emissions and control climate change.

NEW CHANNEL FROM ANCIENT ARCHITECTS: "Space and Planet" launches this month. Please subscribe now at 🤍 Puma Punku is part of a large ancient structure that forms part of the Tiwanaku site in Western Bolivia, believed to date back to around 536 AD. It is a truly incredible feat of engineering. Some blocks of stone are more than 7 metres long, weighing more than 130 tonnes. Some are made of a type of red sandstone, which would have had to have been transported up a steep incline to reach the site, whilst other blocks, including the famous H-blocks, are made of the volcanic rock Andesite. But a new study from Joseph Davidovits, Luis Huaman and Ralph Davidovits, called Ancient organo-mineral geopolymer in South-American Monuments: Organic matter in andesite stone. SEM and petrographic Evidence, shows that far from being incredibly carved rocks, what we are looking at are two forms of ancient geopolymer concrete. The andesite rocks contain organic matter, which is unheard of for a volcanic rock and therefore indicate it is made by artificial means. It may also mean that soon, the researchers may be able to Carbon-14 date the rocks of Puma Punku and we can finally have a good indication of just how old this famous site really is.

Joseph Davidovits and the Geopolymer Institute crew shows that only few people is able to rapidly and easily produce several tons of pyramid stone blocks.
After seeing Paul Cooks video a few months ago giving out instructions on how to make geopolymer, and how it was likely used to construct the Pyramids in Egypt... I decided to order all the material needed to make the stone! Here is the original video Mr. Cook shared on how to make the stone 🤍 Seen in this video, a mix I made last night at midnight (its now noon 12 hours later). 2 cups of water 1 cup of Sodium Carbonate 1 cup of powdered limestone 1 cup of granulated limestone 1 cup of Kaolin Clay 1 cup of clam shells Mix in this order above, start with clear water first in a container, then add the materials and it will harden within 2 hours, and by 12 hours it is becoming hard as stone (stronger than concrete). I smashed the sphere of geopolymer onto the concrete very hard, not even a chip off happened! I am still working on the water proofing, which should just involve a single painted on layer of Water Glass Sodium Hydroxide Sodium Silicate. All these materials were available in ancient times by the way. Thanks to Paul Cook for the instructions in this video: 🤍 Here is a link to Paul Cooks other videos: 🤍

Sacsayhuaman, near Cusco Peru, is an incredible structure made up of huge blocks of perfectly cut and fitted stones. Geologists were on site in 2012 to take samples and do analysis. The rock type used is a fine limestone and by comparing samples to natural rock outcrops, it is very likely the wall blocks were quarried directly on site, not brought in from miles away. But some have speculated that these blocks are artificial, moulded from a geopolymer lime-based mixture and left to set. But under a microscope, we know this cannot be the case. We find small, naturally-occurring calcite veins criss-crossing the rocks. These types of microstructures do not form in man-made concrete. It’s not the same process as lime-leeching or efflorescence. This clears up the mystery. These rocks are natural, quarried from local outcrops.

Watch Part 2 here: 🤍 Watch Part 3 here: 🤍 Watch Part 4 here: 🤍 To sum-up: Alkali-Activated Materials (AAM) are NOT Polymers, so they cannot be called Geo-Polymers. Geopolymers are NOT a subset of AAM because they are not a calcium hydrate alternative, the chemistry is radically different. Those who claim that both terms are synonyms are promoting a misleading scientific belief. Learn why by watching these two videos. Many scientists and civil engineers are mistaking alkali activation for geopolymers, fueling confusion, using them as synonyms without understanding what they really are. In his four recent keynotes at the Geopolymer Camp 2014, 2015, 2016 and 2017, Prof. J. Davidovits explained why Alkali-Activated-Materials are not Geopolymers, or why alkali-activation is not geopolymerization. We have selected and merged into one video all the sequences that had been dedicated to this issue in the GPCamp-2014 keynote. The new video is titled: Why Alkali-Activated Materials are NOT Geopolymers. You will finally understand why they are two different systems. In this first part, Prof. J. Davidovits explains the main differences between AAC —Alkali-Activated Cement or Concrete—, AAS —Alkali-Activated Slag—, AAF —Alkali-Activated Fly Ash— and Slag-based Geopolymer cement, in terms of chemistry, molecular structure, long-term durability. In a second part, on hand of the industrialization of Slag/fly ash-based geopolymer cement/concrete implemented by the company Wagners, Australia, he focusses on the results provided by the carbonation testing data obtained for OPC, AAS and EFC —Slag/fly ash-based geopolymer—. The tests were carried out at the Royal Melbourne Institute of Technology RMIT in Australia. Geopolymer behaves like regular Portland cement, whereas AAS gets very bad carbonation results.

Earth Friendly Concrete® (EFC®) is a traditional concrete that uses no ordinary Portland cement. Instead, EFC® uses a geopolymer binder system made from the chemical activation of two industrial waste by-products - blast furnace slag (waste from iron production) and fly ash (waste from coal-fired power generation). This alternative eco-friendly binder technology reduces the carbon emissions associated with normal Portland cement and also has a much lower embodied energy. Importantly, the engineering and construction properties of this new environmental concrete are as good, and in some areas better, than normal concrete.
