What Is Hempcrete?
Hempcrete is a bio-composite that is made from the inner wood core of the hemp plant and mixed with the lime and other natural materials. It is also known as hemp-concrete.
Hemp is a plant that grown without any use of plant protection chemicals. It required a very little amount of water and it will also help to contribute to the agricultural regeneration of soil.
Hempcrete is basically a bio-based Construction material that is widely used to build, renovate, and restore various types of structures. Hempcrete has low density but it can be used for minor structural purposes.
Hempcrete is a carbon-negative material that consumes carbon which makes it an ecofriendly construction material.
Hempcrete is fully Recycled material which can be reused for making fertilizers. It has a low carbon footprint and environment-friendly construction material.
There are many products that are available in the market which are made up of Hempcrete. But Hempcrete blocks are widely used in the construction.
Hempcrete blocks are lightweight, durable, and have good insulation. Hempcrete blocks are generally used for insulation purposes.
Hempcrete consists of high silica content which helps to give high strength. The main function of the silica is to bind other natural materials with each other.
The density of hempcrete ranges from 300 to 900 kg/m3.
The compressive strength of hempcrete blocks is found to be around 1 Mpa.
Advantages of Hempcrete Blocks
- Hempcrete blocks are eco-friendly and energy-efficient construction material.
- Hempcrete blocks help in the thermal regulation which regulates the temperature of the building.
- Hempcrete blocks are very light in weight and can transport easily from one place to another place.
- Hempcrete blocks help in contributes to the breathable walls.
- It is a disaster-resistant, which helps to ensure the safety of the buildings.
- It is a strong and durable eco-friendly construction material.
- Hempcrete blocks have good sound as well as heat insulation properties.
- Hempcrete blocks are fire resistance.
- Construction with the help of Hempcrete blocks is easy and fast.
- Hempcrete is a sustainable construction material.
- It provides a healthy indoor environment for the occupants.
- Hempcrete can be the best option for which is used in the Renovation of the buildings.
- It has high moisture handling capacity.
- It is also used for decorative work.
Disadvantages of Hempcrete Blocks
- Hempcrete walls are thicker in size as compared to other walls which reduce the carpet area.
- Hempcrete has low compressive strength.
- It also has low elastic modulus which makes it unsuitable for direct loads.
- It cannot be used for heavy loads, it requires frames to carry loads.
- The raw material required for Hempcrete does not grow everywhere.
- Hempcrete cannot be used in the foundation of the buildings.
- Hempcrete is not readily available as compared to the concrete, because it is difficult to find hemp.
- Builders have a lack of knowledge about Hempcrete Construction.
Applications of Hempcrete
- It is widely used in the Extension or Renovation of the buildings.
- It is used for insulation for the old buildings.
- It is also used for plastering work.
- It is lightweight so that it is the best option where the dead load of the building is required to be less.
- It is used for floor as well as roof insulation.
- It is also used in the external and internal insulation of the buildings.
- It is used for creating an air-tight seal around the home.
Hempcrete is a natural Construction material which comes with excellent insulation properties.
Hempcrete was constructed by mixing the raw materials on the site and placing that mixture in the formwork.
Nowadays there is an increase in the demand of Hempcrete due to its various excellent properties.
There are many Hempcrete products are available in the market among which the Hempcrete is one of the best and widely used Hempcrete product in the Construction.
Here are the steps which are used while the Construction of the Hempcrete blocks.
Mixing of Hempcrete
- The raw materials like hemp shives, lime and water are mixed properly in the right proportion.
Moulding of Hempcrete
- The mixed Hempcrete is then fill in the mould and compacted properly so that the air voids get removed.
Curing of Hempcrete
- After that, the blocks are kept for curing in the open air. Curing is very important, which gives strength and hardness to the Hempcrete blocks.
Hemp brick is a solid piece of construction material that is made up of fibre. Hempcrete brick is a natural eco-friendly construction material that is widely used for the construction of green buildings.
The benefit of hempcrete bricks is that it is fire resistance. Once the mixture set it will not catch fire.
Hempcrete bricks are energy efficient and sustainable construction material.
The walls which are made from hempcrete generally range from 250 mm to 500 mm thick in size. Due to this thickness, there is less carpet area, it is good in thermal and acoustic performance.
The bricks which are made from hempcrete does not use for load-bearing structure because hempcrete has low compressive strength.
How to Make Hempcrete Bricks
The process of making Hempcrete bricks is very easy and fast.
Hempcrete is properly mixed in the right proportion. The four parts of hemp and one part of lime which act as a Binder and one part of the water is used for making Hempcrete bricks.
Hempcrete bricks are durable and have various beneficial properties as compared to traditional bricks.
It helps to naturally regulate the building’s humidity and temperature and reduce condensation and energy consumption.
Hempcrete bricks also help to stay free from bacterial attacks.
The Hempcrete price is a little bit high as compared to other Construction material. But it helps you to save money in the long term due to its energy efficiency and excellent properties.
It helps in the thermal insulation of the building. It helps to store heat and keep the indoor environment of the building cool and clean.
