Just Add Water Concrete Mix: Separating Fact from Fiction

Concrete, a ubiquitous building material, has long been the go-to choice for construction projects worldwide. However, with growing concerns about sustainability and environmental impact, a new player has emerged to challenge its dominance – hempcrete. This innovative material has sparked intense interest, particularly among eco-conscious builders and homeowners. But can it truly replace traditional concrete, or is this just another hype? In this article, we'll delve into the world of hempcrete, examining its advantages and limitations, as well as exploring the potential benefits of adopting this 'miracle crop.'

The Cost Factor

When it comes to pricing, hempcrete seems to have a significant advantage. According to our data, the average cost of standard concrete per yard is around $108 or 10,800 cents (NRMCA). In contrast, hempcrete's cost differentials are relatively low, making it an attractive option for those looking to reduce their environmental footprint. Our examined batch weighs 3,690 pounds per yard, with a corresponding cost of $0.0293 per pound.

Hydration and Hardening

Standard concrete undergoes hydration, where water reacts with the Portland Cement to harden (Popular Mechanics). This process is crucial for its structural integrity. Hempcrete, on the other hand, can be reused through milling and rehydration. This property not only reduces waste but also makes it a more sustainable option.

Applications and Advantages

Hempcrete has been reported as better for the environment, easier to grow, and 'has been suppressed for decades by corporate interests' (American Hemp, LLC). With 25,000 potential uses, hemp is often touted as a miracle crop. In concrete applications, it offers several benefits:

* Stem walls (part of the foundation) can be constructed using hempcrete.

* It provides strong insulation, flame resistance, pest resistance, moisture balancing, and biodegradability when exposed to water.

Separating Fact from Fiction

The notion that hempcrete can replace standard concrete is a topic of ongoing debate. While it has its advantages, several factors need to be considered before making the switch:

* Cost: Although hempcrete may seem cheaper upfront, the cost difference might not be significant enough to justify the transition.

* Performance: Concrete's strength and durability are unmatched in many applications.

In conclusion, while hempcrete shows promise as a sustainable alternative to standard concrete, it is crucial to separate fact from fiction. Further research and testing will help determine its viability in various construction scenarios. As the saying goes, 'Now is the time for hemp to regain its rightful place.' Will this 'miracle crop' revolutionize the construction industry? Only time will tell.
