it is the ratio of tensile strength to the flexural strength
no ductility
The toughness index of concrete is a measure of its ability to absorb energy and deform without failing, reflecting its ductility and resistance to crack propagation. It is calculated by comparing the area under the load-deformation curve of a concrete specimen during a fracture test. A higher toughness index indicates better performance under impact or dynamic loading conditions, making the concrete more suitable for applications where durability and resilience are critical. This property is essential for structures subjected to varying loads and environmental conditions.
Vebe time is an test index used to define the workbility of concrete, especially for the stiff concrete.
Examples: color, refractive index, density, electrical conductivity, ductility, etc.

Ductility
Hardness is the opposite of ductility.
A gas does not have any ductility.
Ductility, conductor, viscosity, density, etc.
Copper has high ductility, which means it can easily be stretched or drawn into thin wires without breaking. This property makes copper a commonly used material in electrical wiring and plumbing applications.
