Ad-Nano Concrete applications products :
- 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.
