The biggest disadvantage is similarly related to a lack of knowledge: we don’t know how well it works because we simply haven’t used it on a wide variety of construction projects, in varying climates, over varying durations of time. Once hempcrete is more widely used, we’ll know more about how well it works — or doesn’t work. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Interestedinhemp 0 Questions 42 Answers 0 Best Answers 85 Points View Profile Interestedinhemp 2020-06-22T20:33:14-04:00Added an answer on June 22, 2020 at 8:33 pm Hempcrete has been around for many years. It has been used in Europe to renovate some old buildings that are made of stone or lime material. Whilst hempcrete seems to work well a disadvantage of hempcrete is that it is not as strong as residential grade concrete. Hempcrete has a low density and is known for its resistant to cracking under movement. Another issue with hempcrete is that this product must be used with a framing material, however this is similar to other types of building products that require a frame to make the product more sturdy. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Cleverclogs 0 Questions 50 Answers 0 Best Answers 104 Points View Profile Cleverclogs 2020-06-22T21:02:36-04:00Added an answer on June 22, 2020 at 9:02 pm There are a number of drawbacks to using hempcrete, and while some would argue it’s benefits outweigh these; you need to consider these disadvantages carefully before deciding whether or not to use it. 1. As of yet, there are no standardized processes in manufacturing. The end-result is an unstandardised product that is only considered safe for non-structural purposes. 2. There is a lack of evidential research of the material science of this product. 3. At present, the only construction method that has been validated scientifically is that of a timber frame structure. 4. Hempcrete has only been utilized as a non-load-bearing material. 5. Mechanical Durability issues have been widely reported. 6. Hempcrete is not yet known to be suited for all climates. In hotter climates where there is a higher level of moisture, this could result in increased heating occuring in a building. As such, ventilation needs to be considered with due care and attention. As use of the product grows, there will eventually be more evidence-based data on the specific disadvantages, applications, and uses for hempcrete, but for now, it remains a largely undocumented material. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Melody 0 Questions 145 Answers 0 Best Answers 295 Points View Profile Melody 2020-06-22T13:59:55-04:00Added an answer on June 22, 2020 at 1:59 pm Hempcrete is for non-loadbearing applications as a fill material for timber frame construction. Nothing else has really been examined, so it is hard to know exactly how other applications will work. And without standardized manufacturing processes, the product varies which is why it’s only used for non-structural purposes. So far, at least. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp hempbarn32 4 Questions 39 Answers 0 Best Answers 79 Points View Profile hempbarn32 2020-06-22T12:33:46-04:00Added an answer on June 22, 2020 at 12:33 pm The real question should be hempcrete advantages and disadvantages, so we get a better understanding of this material. Advantages of hempcrete a few, stores heat which may help in cold weather.Resistant against mold and non-toxic. The negative side to it is most architects are not familiar with this product and costs are higher. But remember concrete also has disadvantages also. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp torijane 0 Questions 9 Answers 0 Best Answers 19 Points View Profile torijane 2020-06-22T13:59:38-04:00Added an answer on June 22, 2020 at 1:59 pm Despite the fact that hempcrete is much sturdier than traditional concrete, it comes with disadvantages that are definitely tough to ignore. For one, it’s expensive- using hempcrete, if available, can increase the cost of a home by up to 12%! It’s also a biological material, and one must pay very close attention to humidity when using hempcrete as it can mold if left too moist. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Katie Halder 0 Questions 18 Answers 0 Best Answers 36 Points View Profile Saikat Halder 2020-06-22T12:00:24-04:00Added an answer on June 22, 2020 at 12:00 pm Hempcrete is particularly a brand new alternative to traditional concrete we use. It is actually made of hemp waste. Even though hempcrete is made of recycled materials and offers almost the same level of strength, there are certain disadvantages. Not many people have used it for top priority projects, still a lot of research needs to be done on it, much more sticky and thicker than normal concrete, the mechanical properties of hempcrete is not the same like that of traditional concrete – are some of the most important disadvantages. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
