Including several experimental directions, the project aimed to learn about and exploit the potential inherent in the use of mycelium in the construction industry. | |||
First, to replace the already widely used substrate for the growth of mycelium, the mixture of hemp, wheat bran, water and gypsum, with a simpler and cheaper material, with straw. | |||
We wanted to see if the growth can be just as successful with fewer measurements, and ingredients, therefore stepping out from the lab would be possible in the future. | |||
According to our observations, the mycelium grew just as quickly and intensively on the straw, compared to the mixture just mentioned, and no significant difference could be observed on the exterior of the finished objects either. | |||
On the other hand, the mushroom threads formed a close connection between the elements placed next to each other and joined together. It is well proven that even after the 40% size reduction of the test cubes that occurred during the pressure tests, it didn't start to separate where the elements were joined. | |||
During the pressure tests, the compressive strength of the test cubes of each mixture was revealed. A significant difference is that the general substrate, i.e. the mixture consisting of four materials, can carry almost twice as much load as straw alone. This is due to the larger particle size of the straw and its natural tubular design, as a result of which a lower density was achieved, which also greatly affected the compressive strength. If the straw is ground to a smaller size, it could certainly compete with the density of the one made with hemp. |
