Advanced Functional Material- Ultra Fine Nanoengineered Inorganic Polymer Concrete Composites for Multifunctional Applications
Allotropy or allotropism is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of these elements. Allotropes are different structural modifications of an element; the atoms of the element are bonded together in a different manner.
There is a constant drive for development of ultrahigh performance multifunctional construction materials by the modern engineering community. These materials must exhibit enhanced durability and mechanical performance, while at the same time embracing functionalities that satisfy multiple uses in order to be suitable for future emerging structural and environmentally resistant applications.
Consensus in the research community suggests that concrete, the most used construction material worldwide, should be engineered at the nanoscale, where its chemical and physio-mechanical properties can be truly enhanced. This report reveals an innovative multifunctional nanoengineered concrete capable of an unprecedented range of enhanced properties when compared to standard ordinary concrete. These include an increase of up to 100% in the compressive with a 50% reduction in cement, while at the same time an enhanced resistance to thermal destruction by fire. A surprising decrease in water retention compared to normal concrete makes this novel composite material ideally suitable for constructions in areas subject to water saturation.
The unprecedented array of functionalities that are reported in this paper are produced by the addition of water‐stabilized alumino-silicate colloids, an advancement in the emerging field of nanoengineered concrete which can be readily applied in a more sustainable construction industry.
Central California Valley soils technicians have developed a pioneering new technique that uses nanoengineering technology to incorporate clay into low carbon concrete production.
The new composite material is designed to reduce the carbon dioxide footprint found in existing concretes and can be used directly by the construction industry. All of the concrete samples tested are according to ASTM standards and California Department of Transportation specifications for construction.
The new nano-clay-reinforced composite material drastically reduces the carbon footprint of any conventional concrete production method, making it more sustainable and environmentally friendly under California’s SB32 mandate for green-house gas reductions to 2030.
This nascent composite material is an absolute game-changer in terms of improving traditional concrete to meet the need for a Greener California. Not only is it stronger and more durable, but it is also more resistant to chemical attack, making it uniquely suitable for construction in areas which require maintenance work and are difficult to access.
Most importantly, by including this pozzolanic clay composite, producers
can reduce the amount of carbon materials required to make concrete by around 50%. – leading to a significant reduction in GHG emissions.
An unprecedented range of functionalities and properties uncovered during a decade of research are an important step in encouraging a more sustainable, environmentally-friendly construction industry worldwide.
Previous work on using nanotechnology has concentrated on modifying existing clay powder components as used in the cosmetics and ink-jet printer markets.
In the innovative new application, the research team has created a new technique that centers on thin clay mineral powder low in energy demand and compatible with modern, large scale manufacturing requirements.
