Hemp is a versatile and sustainable material capable of absorbing a significant amount of CO2 per hectare. By combining hemp shives with a lime binder, hempcrete is created, a material that combines the strength of concrete with the flexibility of clay. This material naturally regulates heat and moisture, is carbon-negative, and biodegradable.

Within the spatial design for the Finals, hempcrete can be utilised in various ways. For example, it can be used to create pedestals made of high-quality natural materials. This ensures that the design aligns closely with the overarching narrative central to the exhibition; the introduction to the Symbiocene.

By choosing hempcrete as a building material, not only is a sustainable and environmentally friendly choice made, but also a statement about the importance of natural materials in contemporary design. The use of hempcrete contributes to a more circular and responsible approach to the construction sector, demonstrating the potential of innovative materials that can aesthetically and functionally enhance the design process.

The first experiment was largely successful, but the proportions were not quite correct (two parts hemp, one part lime, and one part water). The mix was too dry, causing the materials to not adhere well to each other and resulting in an unsolid block.

In the second experiment, the ratio between the different materials was adjusted. This time, one part hemp, two parts lime, and one and a half parts water were chosen. The intention was to create a substance that could adhere better. To further promote the bonding process, a small amount of wood glue was added to the mix.

Despite these adjustments, unfortunately, it was not successful in creating an improved version, as seen in the photo. The main problem lies in the fact that the plastic box is too large, causing damage to the hemp block when removing it. This issue can be addressed by finding a different mold that is open at the top and bottom, allowing for easier removal of the mold.

Although the desired result has not been achieved yet, these experiments are valuable learning experiences. Adjusting the ratios and finding the right mold can lay the groundwork for further improvements in the process. It is a matter of experimenting, evaluating, and adapting to achieve a good version of the hemp block.

For my third experiment, I opted for a different mold. This mold has an open top and bottom, making it easier to remove the hemp without breaking. The ratios remained the same to maintain consistency in the experiment. This allows me to obtain similar results and accurately investigate the effects of the different mold designs.
