Composite Materials of the Future
Materials of the future will be made from wastes used for their physical as well as chemical properties. Composite technology will result in the development of:
- Materials with new properties that reduce embodied energies and emissions.
- Smart materials with new properties that further reduce lifetime energies.
Robotic building methods of the future will require pumpable highly thixotropic self hardening materials. These materials will be composites as only then can the varying properties required be easily achieved
We are already well on our way to this exciting world of composites. All over the world governments are imposing taxes or introducing laws requiring recycling. With this purpose in mind TecEco have developed cement technology that is low reactivity and has high adhesion to all manner of materials. Our mineral binder system is ideal for the manufacture of composites based on wastes recycled for physical property as well as chemical composition. Paper and plastic for example have in common the physical properties low weight, high tensile strength and low conductance. Bound together in a composite by TecEco Eco-Cement such wastes add value and make ideal green composites with the right rheology for the future. Many wastes will be able to be converted to resources in this way.
The potential of the built environment to utilise these wastes is enormous. The built environment is made of materials and is our footprint on earth. It comprises buildings and infrastructure. Building materials comprise:
- 70% of materials flows (buildings, infrastructure etc.)
- 40-50% of waste that goes to landfill (15 % of new materials going to site are wasted.)
At 1.5% of world GDP Annual Australian production of building materials likely to be in the order 300 million tonnes or over 15 tonnes per person. Over 20 billion tonnes of building materials are used annually on a world wide basis. These materials mainly use virgin natural resources that include many toxic elements combined in such a manner they cannot easily be separated..
The concept of mining waste for physical and well as chemical properties makes much more sense than doing so on chemical property alone. It can be practiced on a decentralised basis by large and small companies alike. Wastes can deliver a wide range of properties to composites and most importantly, using wastes in this way makes zero landfill a realistic destination.
The Built Environment of the Future will be Made with Composites Incorporating Wastes and Delivering new Properties
Construction in the future will be largely done by robots because it will be more economic to do so. Like a colour printer different materials will be required for different parts of structures, and wastes such as plastics will provide many of the properties required for the cementitious composites of the future. A non-reactive binder such as TecEco Tec-Cements can supply the right rheology, and like a printer, very little will be wasted .
Robotic Construction Methods will Require Self Hardening Composites with Highly Thixotrophic or Bingham Plastic Properties
Properties such as ultra low conductance or very high specific heat are all feasible and will be designed into composite materials of the future.
