Although hempcrete cannot be used in foundations, hempcrete can be lighter than concrete. A more lightweight foundation can be poured, so long as it is in accordance with your local building codes and engineer's instruction.
Hempcrete does not exhibit the compressive strength assoicated with concrete - one reason being its not a dense material. It contains lots of small voids, with the result being that there are fewer points of contact between all the individual particles.
Hempcrete can replace standard concrete. Hempcrete is a material that has been around for a long time. Further, it is said to be more sustainable than concrete and a carbon sink. Hempcrete can also be reused through milling and rehydration.
Fiber Properties Hemp fabrics are stronger, more absorbent, more durable, and better insulating than cotton. On the other hand, cotton is ideal for t-shirts, jeans, and other apparel where some stretch is desirable. Cotton fabric is softer and more comfortable against the skin than hemp fabric.
Hempcrete can be used as insulation, flooring, roofing, and even drywall. It is fireproof, waterproof and rot proof provided it is above ground. Limestone is the binder in hempcrete, and it does not need to be heated as much as conventional concrete mixture, reducing energy costs.
Hemp : Hemp requires almost half the amount of water to produce the same amount of cotton. It grows fast which makes it ready for making fibers in much lesser time than cotton. Moreover, hemp produces 200–250% more fiber than cotton cultivated in the same land stretch.
Hemp has a 50% protein content and is regarded highly because it is so easily digestible. Hemp protein also boasts all 20 amino acids, including the 9 essential amino acids. Whey does contain saturated fats as well as cholesterol, while hemp protein only has unsaturated fats.
