Alternatives to Concrete

There are many alternatives to concrete that can be used in a construction project. Among these are Grasscrete, Hempcrete, Papercrete and Aircrete. Each material has its own unique advantages and disadvantages. These materials are also great for the environment. Learn more about the pros and cons of each of these materials so you can make an informed decision.

Grasscrete

When designing a building, it is important to consider safe emergency access. This is not always possible with precast concrete systems because they require infill panels. Additionally, a concrete slab is less durable than a grass-covered area. Grasscrete is a better option because the material has a high penetration rate and has the ability to resist differential settlement. In addition, the material can be peddled as needed once the desired strength is achieved.

Grasscrete can be installed in both concealed and open areas. Unlike concrete, grasscrete is less noticeable and requires fewer resources to maintain than other materials. In addition to being less expensive, grasscrete can be installed more quickly and easily than other materials. Grasscrete forms can be delivered by truckload, making it easier to cover large areas quickly than concrete. In addition, Grasscrete is eco-friendly, aesthetically pleasing, and low-maintenance.

Hempcrete

Hempcrete is an environmentally friendly building material. Unlike concrete, it doesn’t release any harmful toxins when it is growing or being processed into building material. This material also does not contain any oil or mineral deposits which can pollute the indoor environment. Meanwhile, concrete contains calcium silicates and other chemicals that are detrimental to the environment. In addition, the cement manufacturing process requires the use of fossil fuels, which are the third-largest source of greenhouse gas emissions in the U.S. Concrete also limits the ground’s ability to absorb precipitation and cuts off life in the underlying soil.

In addition to being an environmentally friendly alternative to concrete, hemp concrete has many other benefits. It can be made into durable structures that can be used in many mainstream applications. In addition to its superior ecological qualities, hemp concrete also has superior thermal and hygrothermal behavior. Moreover, it helps reduce the need for imported wood.

Papercrete

Papercrete is an alternative to concrete, made from waste paper and recycled as aggregate in the concrete manufacturing process. The use of papercrete is a green building solution that can reduce the resources consumed in the production of concrete. By recycling concrete debris, it is possible to reduce the resource consumption and the environmental impact of concrete production.

Papercrete is also a lightweight alternative to concrete. It is similar to concrete in appearance and can be cast into any shape. However, it does have a tendency to absorb moisture, which reduces its strength. As a result, it is not a good choice for load-bearing walls, but it can be used for other building projects. Papercrete is also more insulating than regular concrete and wood.

Aircrete

Aircrete is a concrete alternative that offers all the benefits of conventional concrete with the added properties of energy efficiency and sustainability. Concrete-based homes tend to feel damp and cold, and Aircrete is a great option for those who want to create sustainable and energy efficient homes. It provides superior insulation thanks to the foam and air bubbles that are built into the concrete. This means that it can provide superior insulating power for a building without the added cost of specialized labor.

Unlike concrete, aircrete is lightweight and easy to work with. It has many advantages over concrete, but it does not have the same strength or compression properties. For this reason, it is best to use concrete for load bearing applications.

Rammed earth

A few advantages of rammed earth over concrete include its low carbon footprint and versatility. Many architects find rammed earth as an ideal material for creating beautiful homes. Its natural color and texture variations give architects a chance to incorporate a variety of styles into their work. The natural color variation also allows architects to reduce their carbon footprint.

Rammed earth is created by compaction of damp subsoil. The right proportions of clay and sand are required, along with a small amount of cement. Stabilizers can also be added to prevent common problems associated with rammed earth. Since cement is not the most environmentally friendly building material, it isn’t recommended for use in rammed earth construction. However, lime and asphalt emulsions can be added to stabilize rammed earth.

Graphene

Graphene is a carbon atom-thick material that can be added to composite materials such as concrete. By adding graphene, composites will be stronger and lighter. The addition of graphene can also make these composite materials more energy-efficient. Some companies are already using graphene in their products.

The strength of graphene is 200 times greater than steel, which means that it could make concrete much stronger and more durable. Researchers are experimenting with different forms of graphene, including graphene nanoplatelets and graphene oxide. The researchers are using a technique called high-shear exfoliation to incorporate graphene into concrete. Graphene flakes suspended in water are injected into the concrete, which makes the material stronger. As the concrete cures, the flakes of graphene anchor themselves into the concrete, which prevents moisture from penetrating the concrete.
