Hempcrete is made by mixing lime and hemp in proportions adapted to the work to be done. This makes it very versatile, and it can be used to build insulating walls, linings, roofs, screeds, attic spaces and renders.
How Is Hempcrete Made?
Hempcrete is a unique building material that is made from a combination of hemp and lime. It is an eco–friendly, breathable, and lightweight material that has been gaining traction in the construction industry in recent years.
Hempcrete has a variety of benefits, including its ability to reduce carbon emissions and provide excellent insulation, making it an ideal choice for green–minded builders.
But how is hempcrete made? Let’s take a closer look. The process of making hempcrete begins with the harvesting of the hemp plant.
The hemp is then dried, milled, and screened to separate the long, strong fibers from the hurds, which are the woody inner core of the plant.
The hurds are then finely ground into a powder–like material called shiv. The shiv is then mixed with a lime–based binder to create the hempcrete.
The amount of binder used in the mixture is determined by the desired strength and consistency of the final product. Generally, the ratio is 6 parts shiv to 1 part binder, although this ratio can vary depending on the desired application.
The mixture is then poured into molds or frames and left to cure. When the hempcrete has cured, it
