Graphene is a two dimensional mesh of carbon atoms arranged in the form of a honeycomblattice. It has earned the title “miracle material” thanks to a startlingly large collection of incredible attributes - this thin, one atom thick substance is the lightest, strongest, thinnest, best heat-and-electricity conducting material ever discovered, and the list does not end there.s
As it is a nanotechnological additive, this material acts as a structural reinforcement, since it increases the flexibility of the concrete by 45%.
The main function of fibers in concrete is to improve its toughness and ductility, which means that the concrete can better resist cracking under tension and bending. When fibers are added to the concrete, they act as small reinforcing elements that help to distribute the tensile forces that develop in the concrete. This results in a more durable and resistant concrete, which can withstand greater loads and is less likely to crack.
✔ Reduces shrinkage cracking - plastic ✔ Reduces segregation. ✔Reduces bleeding water. ✔ It is a three-dimensional reinforcement in comparison with the two-dimensional welded Mesh
Macrofibers are included in the concrete to increase the toughness of the material, that is, to make the structures, even after the matrix cracks, able to continue being loaded.Its inclusion forms a three-dimensional matrix, creating macrogrids throughout the volumetric space of the concrete that act by absorbing the efforts after the concrete has set, produced by the flexing of the pavement under service loads.
Macrofibers are considered to be better steel fibers as reinforcing concrete for several reasons:
✔ They have a larger aspect ratio (length to width ratio) than microfibers, which allows them to provide better distribution of tensile forces in concrete.
✔ They have a higher modulus of elasticity than the concrete matrix, which results in a more efficient transfer of stresses from the concrete to the fibers.
✔ They have a higher yield strength than the concrete matrix, which means that they can carry a higher load before they begin to deform.
Overall, macrofibers are better steel fibers as reinforcing concrete because they have a higher aspect ratio and higher modulus of elasticity and yield strength than microfibers, which makes them more efficient in distributing tensile forces and carrying loads. Additionally, they are easier to mix into the concrete and have a wider range of application and lower dosage rate.
✔ They can be added to the concrete mix in a dry form, which makes the mixing process easier and more efficient.
✔ They can be used in a wider range of applications, including precast concrete, shotcrete, and sprayed concrete.
✔ They have a much lower dosage rate than microfibers, allowing for cost savings on the material and transportation.
