Describe how 'HEMP-CRETE' works and give 2 advantages and disadvantages.
Hemp-crete is a building material made from the woody core of the hemp plant. It is mixed with a lime-based binder to create a lightweight, breathable, and insulating material. Hemp-crete is used as an insulation and structural material in walls, floors, and roofs. It is also used as a fire retardant and soundproofing material.
Advantages:
1. Hemp-crete is a sustainable building material that is carbon negative, meaning it absorbs more carbon dioxide than it produces.
2. Hemp-crete is lightweight and breathable, making it an ideal material for insulation and soundproofing.
Disadvantages:
1. Hemp-crete is more expensive than traditional building materials.
2. Hemp-crete is not as strong as traditional building materials, so it is not suitable for load-bearing structures.
