Graphene oxide (GO) has obtained great interest in the construction industry, particularly in enhancing the performance of cement-based materials such as mortar and concrete.
Graphene Oxide is the substance that we propose should be utilized in concrete since it gets easily dispersed with water-based systems compared to graphene and rGO. GO’s functional groups and concrete’s alkalinity provide stability and efficient distribution and adhesion within the concrete matrix.
Advantage of Graphene Oxide in Concrete:
Enhanced Mechanical Properties:
GO can significantly increase the compressive, tensile, and flexural strengths of Concrete . This is attributed to its high surface area and strong interfacial bonding with the cement matrix.
Crack Bridging and Arresting:
GO has a high aspect ratio and excellent mechanical properties, which allow it to bridge and arrest microcracks, thereby enhancing the durability and fracture toughness of the mortar.
Increased Strength:
Studies have shown that even small amounts of GO can substantially increase the compressive and tensile strength of Concrete .
Durability:
GO-modified mortars exhibit improved resistance to water permeability, chemical attacks, and freeze-thaw cycles, enhancing the longevity of structures.
Flexibility in Applications:
Enhanced mechanical properties and durability make GO-modified Concrete suitable for various applications, including high-performance buildings, bridges, and infrastructure projects.
Graphene for Concrete Applications Products :
Adnano technologies has been working towards concrete application with their group of researchers with great dedication and successfully created fabulous products which not even increase the strength but are also environmentally conscious. They are mentioned below,
- UNIGO : Graphene oxide product for concrete applications
- Nano-GTN : is a paste admixture of graphene nanoplatelets
- Nano-GTX : is a paste admixture of few layer graphene
Dosage and Application
- Recommended Dosage: 15g per 50kg bag of cement is the recommended dose; 30g per 50kg bag of cement for more higher strength.
- Addition: First the paste needs to be added in small quantity of water and mixed well to get concentrated solution, later the concentrated solution needs to be diluted in total water as per the water/cement ratio.
Product Benefits :
- Improved workability: The mixture is workable for longer enabling max plasticity to be achieved.
- Enhances flexibility: Leads to significantly improved crack resistance in the plaster/mortar mix.
- Minimizes cracking and blistering: Facilitates homogenous mixing and reduces cracking due to retarding effect leading to a denser mix.
- Develops higher strength in all cemented applications.
Conclusion:
In the dynamic realm of construction materials, the integration of graphene oxide into Concrete emerges as a promising avenue for improvement. This research not only introduces a novel modification but demonstrates tangible enhancements in mechanical and durability properties. As we seek resilient and sustainable solutions for the built environment, graphene oxide-modified cement mortar stands as a beacon of innovation.
