Thanks to graphene, Graphenano Smart Materials products improve the mechanical performance, the quality and performance of conventional building materials.
SmartADDITIVES is a GRAPHENE TECHNOLOGY adapted for the manufacture of multifunctional admixtures incorporating graphene materials that, when added to concrete and mortars, produce substantial improvements in mechanical performance, durability and thermal conductivity.
Specifically, SmartADDITIVES technology provides mechanical, durable and conductive improvements by acting as an internal molecular mesh in the concrete.
In terms of sustainability, the application of these latest-generation graphene additives provides the ability to maintain the durability and strength of concrete by reducing the clinker factor, which is responsible for the largest percentage of CO2 emissions contributed by cement, the main component of concrete.
All these improvements in the properties of concrete are based on a physical-chemical basis, which is due to the fact that nanomaterials transfer their properties to this composite when they are added during the mixing process. In this way, graphene reacts with free lime during the cement hydration process, chemically bonding to its structure and transferring its mechanical properties to densify the cementitious matrix and make it more resistant.
In this way, it is possible to reduce the amount of cement needed for the concrete to reach the same level of performance required by the standard and thus contribute to the decarbonization of the sector. By using SmartADDITIVES graphene additives, the carbon footprint in all processes can be reduced by around -20% annually.
Likewise, graphene-based materials have a particle size of nanometers (nm) that occupies pores in the concrete that were previously occupied by air. Thus, graphene gives concrete its hydrophobicity, preventing water from entering by penetration or absorption. This phenomenon gives the concrete improved durability, prolonging its useful life and, at the same time, reducing maintenance costs.
