What is Hemp Crete?
Hempcrete also known as hemp lime, is a bio-composite material that can be used in
Uses of Hempcrete :
construction as an alternative to materials such as brick, concrete and traditional insulation. It can be used for walls, floors and roof insulation. It provides excellent acoustic and thermal insulation, its light weight and reduces construction cost and its environment friendly.
What is Hemp Crete made of?
Hempcrete is a bio-composite made of the inner woody core of the hemp plant mixed with a lime-based binder. The hemp core or “Shiv” has a high silica content which allows it to bind well with lime. This property is unique to hemp among all natural fibers. The result is a lightweight cementitious insulating material weighing about a seventh or an eighth of the weight of concrete.
Advantages of Hemp Crete :
Hempcrete is a very useful Hemp product which has following properties :-
Environment Friendly construction material- Hempcrete is carbon negative. When we manufacture it, more carbon dioxide is consumed than emitted. Most of the raw materials are not only sustainable, they are renewable too.
Increases Farmers Income -Mere food crops do not create enough income for the survival of farmers and the economy moving away from bio-based is seriously hurting them. The raw materials that are used to produce hempcrete come from agriculture. In fact, the raw materials for all bio-based building materials come from agriculture. By adopting hempcrete products in projects we will be contributing to the welfare of farmers from whom the hemp stalks are bought. The manufacture and retail of hempcrete could improve the income of farmers by up to 20% per annum.
Enabling an Ecosystem :- With the world looking at an impending doom because of global warming and climate change owing to a non-renewable manufacturing industry, it is important to lay a foundation in renewable sources. Since infrastructure is the foundation for manufacturing industries, by establishing it using renewable materials would inspire a shift towards a bio-based economy. Furthermore, adopting bio-based materials also has social benefits by making agriculture more profitable, sparking innovation, employment and growth in the agricultural industry. As a result, an entire geoengineering process for mitigating climate change can be executed profitably without additional inputs.
Cost Effective :- Making the case stronger for itself, the larger unit sizes and lightweight of hempcrete blocks can help reduce construction costs by up to 25% initially. With density lesser than that of water, the dead loads of the building can be reduced drastically as compared to red bricks or other conventional building materials resulting in considerable savings in steel and concrete. Additionally, the larger block sizes similar to that of AAC blocks would require lesser mortar joints, and the flat finished surface of hempcrete would require lesser plastering. The use of lime in hempcrete also means the wall is only set to get stronger with time, improving it’s durability.
Apart from the normal properties that would be expected from a walling material, hempcrete also has additional advantages such as thermal insulation and hygrothermal behaviour. Put simply, hempcrete has the ability to regulate indoor relative humidity thus enhancing the thermal comfort of the occupants, resulting in considerable electricity savings from heating and cooling.
Our Goal with Hemp Crete :
A good business cares not only for profits but also for the society and the planet. It has been proven time and again that a business that cares for sustainability is always more profitable.
Being an agriculture based product which grows naturally (No Fertilizers, no pesticides required and very less water requirement), it will boost farmers income significantly.
Hempcrete is a low cost sustainable and renewable building material which can be a catalyst to achieve “Affordable Housing for All” goal.
The primary application of Hempcrete is to build walls for small houses. Also it can be used to form floor tiles, roof insulation, False ceiling and shuttering.
