Texas A&M University Given Hempcrete Research Funds By U.S. Department of Energy,

Under a project funded by the U.S. Department of Energy, researchers at Texas A&M University are working to 3D print buildings using hempcrete.

Hempcrete has been used for thousands of years for construction purposes – and not a lot has changed in the mix during that time. The versatile building material primarily consists of hemp hurd/shiv, – the woody core of the hemp plant – lime and sand.

Hempcrete offers a number of advantages in building; including being breathable, a high insulation value, high fire resistance, insect and mold resistance and good sound dampening attributes.

Additionally, while conventional concrete production is energy and carbon emissions intensive, hempcrete has a net carbon-negative environmental effect. This means hempcrete can absorb more carbon from the atmosphere than released during production and construction.

Supporting the Texas A&M University’s work in 3D printing hempcrete is a $3.74 million grant from the Department of Energy under the HESTIA program. This program aims to support the development of technologies that cancel out embodied emissions while transforming buildings into net carbon storage structures.

The Texas A&M University team is being led by Petros Sideris, assistant professor in the Zachry Department of Civil and Environmental Engineering. Other team members include Manish Dixit, associate professor of construction science,Wei Yan, professor of architecture, Maria Koliou, assistant professor of engineering, Professor Zachary Grasley and Anand Puppala, professor of engineering. .
