3D Printed Geopolymer, The Pyramids & Roman Construction | The 10,000 Year Home

" Jan 28, 2022

At World of Concrete 2022 I got the opportunity to speak with the Geopolymer International team about a topic that I have been wanting to do a video on for a long time, Geopolymers! Everyone looks to geopolymers as an environmentally friendly alternative to concrete. Until now I really didn't have any understanding of how this silica based binder differers from the concrete other companies are using. Next week I will release a video touring their print facility with their founder and going into more detail on their printer and mixing equipment.

First house printed in Geopolymer Cement (GP Intl & RENCA)

"Aug 30, 2023 IUT DE L'AISNE

Two presentations are included in the video: 00:00 First Printed House in Geopolymer Cement, by William Hoff (Geopolymer International), Emmanuel Roy and Jon Scott (StrongPrint3D) 10:24 Fight Against the Nature, by Alex Reggiani, Marina Dudnikova and Andrey Dudnikov (RENCA) Watch Jarett Gross video:    • First Geopolymer 3D Printed Building ...   @automateconstruction In April 2023, Geopolymer International, Renca and StrongPrint3D came together in Las Vegas, Nevada to pioneer the world’s first 3D-printed house made entirely from geopolymer cement. Despite the extreme heat and frequent winds in the Las Vegas desert, their teams worked tirelessly over several weeks, using large robotic printer equipment to layer the geopolymer cement to construct the house piece by piece directly on site. There were many challenges along the way, such as cement drying and setting quicker than expected in the hot weather. Adaptations had to be made like modifying cement mixtures. Heavy winds also disrupted prints on some days. However, through ongoing collaboration and adjustments to their process, the companies overcame these hurdles. Finally, they announced the successful completion of the fully 3D-printed house, proving the feasibility of building structures with this innovative method and opening doors to future sustainable housing applications using geopolymer materials.

Are Geopolymers BETTER than Portland Cement?

The first 1,000 people to use the link will get a 1 month free trial of Skillshare: https://skl.sh/belindacarr05221 Researchers around the world are trying to find an alternative to traditional cement and concrete that is less destructive to our planet. 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. Link to my Patreon page:   / belinda_carr   Chapters 0:00 Introduction 1:13 Invention of geopolymers 1:40 Waste materials 3:08 Chemical reaction 3:35 Geopolymer projects 4:35 Advantages 6:27 Sponsorship 7:11 Disadvantages 8:12Conclusion Scientists use a variety of waste materials, industrial byproducts, and minimally processed natural materials instead of Portland Cement. 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. -------------------- SOURCES:    • 7 questions à Joseph Davidovits sur l...   https://www.youtube.com/watch?v=znQ bk_yBHre4    • Geopolymers: what are geopolymers mad...      • Brisbane West Wellcamp Airport projec...      • EFC geopolymer pavements at Wellcamp ...      • Video      • Video   -------------------- Fluffy by Smith The Mister https://smiththemister.bandcamp.com Smith The Mister https://bit.ly/Smith-The-Mister-YT Free Download / Stream: https://bit.ly/stm-fluffy Music promoted by Audio Library    • Fluffy – Smith The Mister (No Copyrig...   --------------------- Disclaimer: This video was created for educational/informational purposes and qualifies as Fair Use.
