WEST LAFAYETTE, Ind. \u2014 Jeffrey Youngblood<\/a>, a Purdue University researcher, has increased the strength and resilience of cement by integrating patent-pending chemically modified cellulose nanocrystals and nanofibers that he has developed.<\/p>\n\n\n\n

Mechanical tests show a 30% increase in concrete\u2019s flexural strength, or the ability to resist bending when an external force is applied, when 0.2% volume of the nanocellulose is integrated.<\/p>\n\n\n\n

Youngblood is a professor and graduate chair in the School of Materials Engineering<\/a> and an affiliate of the Division of Environmental and Ecological Engineering<\/a>, a stand-alone academic unit in the College of Engineering<\/a>.<\/p>\n\n\n\n

Youngblood and his team found that by increasing the heat of hydration, the chemically modified nanocellulose reacted to improve the behavior of cement paste in a variety of chemical reactions.<\/p>\n\n\n\n

\u201cThis results in a greater potential to alter microcracking of cement and bolster the mechanical properties for better performance,\u201d he said. \u201cWe validated this through isothermal calorimetry and thermogravimetric analysis.\u201d<\/p>\n\n\n\n

Youngblood disclosed the use of the chemically modified cellulose to the Purdue Innovates Office of Technology Commercialization<\/a>, which has applied for a patent to protect the intellectual property. Industry partners interested in developing or commercializing the innovation should contact Dipak Narula, lead technology development liaison and assistant director of business development and licensing \u2014 physical sciences, at dnarula@prf.org<\/a> about track code 70131<\/a>.<\/p>\n\n\n\n

Applications and next development steps<\/h2>\n\n\n\n

The applications for the Purdue innovation include road, bridge and building construction.<\/p>\n\n\n\n

\u201cIt supports the widespread effort to divert from traditional, unsustainable engineering practices and instead opt for materials with a minimal carbon footprint,\u201d Youngblood said. \u201cThe chemically modified nanocellulose offers a naturally sourced solution to make cement more eco-friendly and reduces the volume and demand of raw materials.\u201d<\/p>\n\n\n\n

Youngblood said more research will be conducted into the best surface treatments, ratios, types of cement, supplementary cementitious materials and additives.<\/p>\n\n\n\n

Youngblood received funding for his research from P3Nano, a partnership between the U.S. Endowment for Forestry and Communities and the U.S. Forest Service.<\/p>\n\n\n\n
