các kiến trúc sư tìm đến vật liệu dựa trên cây gai dầu (thay bê tông) có thể cách mạng hóa cách chúng ta xây nhà...

In search of more sustainable (có thể chịu được) ways to build our homes, some architects are turning to a surprising (đầy bất ngờ) resource — hemp (cây gai dầu), the sister plant to cannabis, which can be transformed into a material called hempcrete.
What is hempcrete?
Hempcrete is a carbon-negative building material made out of hemp, which is increasingly being used in place of concrete.
The biocomposite material is created from hemp shiv — the woody core of hemp stalks (thân cây) — and mixed with a binder, such as lime powder, and water.
Hempcrete is most often suited for building internal walls (tường phân chia các phòng) and insulation (cô lập), but it might also appear in roofs (mái nhà), attic (gác xép) spaces, and flooring screeds (lớp láng nền).
Why is hempcrete important?
For one thing, hemp makes an extraordinary (khác thường) carbon sink when it is growing — research suggests that the crop can capture twice the amount of carbon dioxide that trees can.
That carbon dioxide is then locked away in the walls of your hempcrete home for as long as it stays standing.
