What is ECC?
|
|||||||||||||||||||||||
|
1. |
High ductility---High tensile strain capacity, and high fracture resistance. |
|
 |
Strain exceeding 3%, representing several times of magnitude higher than conventional FRC. | |
|
2. |
Fracture with multiple and micro-crack dispersion |
|
|
|
|
Preventing water permeability or leakage, and neutralization of cementitious matrix. |
|
3. |
Low fiber volume fraction---Typically less than 2vol% is sufficient. |
|
|
4. |
Economically suitable and good workability |
