With the construction industry paying more and more attention to carbon emission reduction and sustainable development, choosing environmentally friendly building materials has become an important trend, and EPS Cement Sandwich Panel is a typical representative of green low-carbon wall materials. The raw materials of the panel include cement, EPS particles, and fly ash, making full use of industrial waste fly ash that would otherwise cause environmental pollution, reducing the consumption of natural resources. No harmful volatile substances will be released during the whole production and use process, and the wall will not produce any radiation or toxic gas, creating a healthy indoor living environment for occupants. Compared with the production process of traditional clay bricks that consumes a large amount of cultivated land resources and produces a lot of carbon emissions, the production process of EPS Cement Sandwich Panel has much lower carbon emissions, which helps to reduce the overall carbon footprint of the construction project. The panel can be recycled and reused after the end of the building’s service life, almost no construction waste will be generated, which conforms to the development trend of circular economy in the construction industry. Many green building certification projects have taken this panel as the preferred wall material to obtain corresponding environmental assessment scores.
