Feature CO2 Eco-Structure

Versatile Multi-functional Material

CO2 Eco-Structure creation is represented by the chemical formula below.

The CO2 Eco-Structure has never been used as a building material, so various experiments were conducted to confirm its strength. It was found that adding epoxy resin not only increases tensile strength, but also improves heat resistance, electrical insulation, and waterproofing for the Type II CO2 Eco-Structure. In other words, CO2 Eco-Structure possesses the mechanical properties of two materials, which can be employed according to the required performance and cost limitations.
The mechanical properties are summarized below.

Potential Structures for CO2 Eco-Structure

Choosing between Type (I) and Type (II) depends on the amount of tensile strength needed for the structure. The illustration below describes possible structures for each type.
Type (I) is made just as the chemical formula states, by injecting CO2 to damp sodium silicate sand. This means that the solidification process absorbs CO2, the cause of global warming.

圧縮・せん断抵抗で可能な空間の骨格

Similar to stone, Type (I) allows for masonry, arch structures, and domes.

 
Co2+nで可能となる空間の骨格

Type (II) utilizes epoxy resin to increase tensile resistance and stably fix the CO2.
As tensile strength is increased, the potential to design structures with more open space in low-rise buildings is possible.

Environmental Benefits of Epoxy

Using epoxy negates the necessity of steel, thereby reducing CO2 generated during steel production.

The CO2 Eco-Structure has been designed with the environment in mind. The next section will introduce current examples of how we plan on using this new technology.
