HydroGraph Clean Power has announced its second research study in partnership with Arizona State University (ASU) highlighting the advancements in extending the use of HydroGraph’s Fractal Graphene™ into cement and concrete applications.
The report reportedly validates the potential of HydroGraph’s graphene for the construction industry, with graphene-enhanced concretes offering practical and sustainable options for high-performance applications, from ultra-strong construction materials to cutting-edge 3D printing techniques.
HydroGraph and ASU have discovered that ultra-low doses of Fractal Graphene™ (0.02%) can enable higher use of supplementary cementitious materials (SCMs) while delivering up to 70% better early-age performance.
Further, two graphene types produced by HydroGraph – Fractal Graphene™ and Reactive Graphene – were incorporated into cementitious binders at ultra-low dosages (≤0.02% by weight of the binder, rather than the total weight of concrete or cement mixture) in the study. The addition of HydroGraph’s graphene in minimal quantities led to impressive results, including significantly improving compressive strength by up to 21% after 28-day curing. The increase in strength enables the use of less cement, while maintaining the same level of strength, with a reduction of 16.7% less cement.
“These findings support the use of HydroGraph’s graphene in innovative concrete solutions, such as ultra-high-performance concretes and 3D-printed structures, while promoting sustainability,” said Prof. Narayanan Neithalath of School of Sustainable Engineering and the Built Environment at State University, who led the study.
“Our Fractal Graphene™ has been shown to perform very well, as an additive, in many forms of composites, leading to significant light weighting in these applications. With the present study, we are extending the applicability of Hydrograph’s Fractal Graphene™ into cement and concrete applications, where we show the possibility of making high performing construction materials with significantly improved sustainability,” said Kjirstin Breure, President and CEO of HydroGraph.
