Having explored the sustainable properties of hempcrete, let us now delve into the process of making this eco-friendly construction material. To illustrate its practical application, we will examine a hypothetical case study where an eco lodge is built using hempcrete.
The Process of Making Hempcrete
To begin with, the production of hempcrete involves three key steps: harvesting and processing hemp stalks, mixing them with a binder and water, and finally casting the mixture into molds for curing. The first step entails cultivating industrial hemp crops specifically bred for their fibrous stalks. Once matured, these plants are harvested and processed to extract the inner woody core known as hurd or shiv. This hurd is then finely ground to create a lightweight aggregate that forms the basis of the final material.
Next, in order to bind the aggregate together, a hydraulic lime-based binder is added along with water. The ratio between binder and aggregate can vary depending on factors such as desired strength and insulation properties. This mixture is thoroughly mixed until it reaches a homogeneous consistency resembling wet sand. It is important to note that no heat or energy-intensive processes are involved during this stage.
Finally, once mixed, the hempcrete is poured into formwork (molds) which define the shape and size of individual building components such as walls or floors. Over time, typically several days or even weeks depending on environmental conditions, the hempcrete cures naturally through carbonation – a process where carbon dioxide reacts with minerals present in lime – resulting in solidification and hardening of the material. During this curing period, it is essential to maintain suitable humidity levels to ensure proper mineralization.
