Home » EARTH, FEATURED, WATER 2 February 20106,411 viewsOne Comment It’s probably not a good idea for another architect to be spreading the word about a ”building in a bag” developed by architects and Concrete Canvas co-founders Peter Brewin and William Crawford, but it’s just such a clever and useful concept that I can’t keep it to myself.
Besides, they’re not very pretty (the buildings – I haven’t laid eyes on Peter Brewin or William Crawford) so I don’t think we’ll be officing or living in Concrete Canvas Shelters except under the most extreme circumstances: the local design review board starts experimenting with peyote for example, or suddenly people only want buildings that look like trilobytes.

Reservoir materials list ... Improved Concrete Via Use Of Sunflower Seed Husks. Recycling Published on May 1st, 2013 | by James Ayre An improved form of concrete, made by utilizing a waste material of the agricultural industry — sunflower seed husks — has been created by researchers at the Namik Kemal University in Turkey.
The husks are a waste product of the vegetable oil and food industry, and are produced in enormous quantities, so any potential use for them would be a big plus with regards to waste reduction.

Studio Edirisa » Blog Archive » 1cm of concrete + cloth + chicken mesh = the death of the iron sheet? Role models & bad models21 May 2010 The Faculty of Technology at Makerere University (Kampala, Uganda) last evening hosted a presentation by an impressive man, George Nez.
He came to discuss the pilot project that he had been leading for a month, and the innovative roof he had spent a lifetime promoting. Are you also tired of iron sheets that boil us up in sunshine and stop our talking in rain? George’s visit is thanks to Dr. Moses Kizza Musaazi, an inventor and a lecturer in electrical engineering. It starts with a simple wooden frame which gets covered by cloth… … and chicken mesh. Can 'Green Cement' Make Carbon Capture and Storage Obsolete? Calera and Novacem use concrete to capture CO2 » Innovation Toronto. Image via Wikipedia It just looks like mud, and appears to do nothing except sit there and harden. The fact is, though, concrete is the world’s third-largest source of man-made carbon dioxide.
Overview « Novacem. Novacem has developed a new cement based on magnesium oxide which will address the carbon problem faced by the cement industry, and as a result will contribute significantly to an overall shift to a low carbon world.
Production of our cement is carbon negative; more carbon dioxide (CO 2 ) is absorbed during the process than is emitted. We aim to offer cost parity with traditional cement, even before any cost of carbon is factored in, and also performance parity. Abundant accessible sources of the magnesium silicates we use to produce magnesium oxide exist on Earth, and will support large scale roll out of Novacem cement production. Our long term vision is to be adopted on a broad basis and eventually to represent a significant percentage of cement industry production. Calera Expands Options for Capturing Carbon. Nature isn’t as bountiful as once anticipated, Calera has learned.
The sometimes controversial startup originally focused on the idea of mixing carbon dioxide with seawater containing traces of calcium and other minerals to produce calcium carbonate, one of the key ingredients in cement. The process -- ideally -- would sequester greenhouse gases from power plants and industrial sites fairly inexpensively and curb the need to mine carbonates, an energy intensive process, for the construction industry. A key element to the concept involves exploiting exotic polymorphs, or forms, of calcium in sea water to minimize the amount of energy and additional raw materials required to turn flue gases into a solid. It turns out, however, that the brines infused with the appropriate feedstocks aren’t as common as once believed, says new CEO Will Roach, and they often aren’t located right next door to power plants.
