2. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Filler can have a negative or positive effect on fatigue resistance depending on the filler type and shape. In general fillers create small discontinuities in the matrix. This can contribute to crack initiation point. If the filler is brittle fatigue resistance will be low, whereas if the filler is very ductile the composite will be fatigue ...

3. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   The curing of concrete when it continues to harden after its initial setting and progressively develops its mechanical strength is a critical phase to avoid unwanted cracks in concrete. Depending on the temperature (summer or winter conditions) and thus on the cement hydration kinetics controlling the setting and hardening rate of concrete ...

4. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.

5. Controlled low strength material - Wikipedia

   en.wikipedia.org/wiki/Controlled_low_strength...

   Since flowable fill is normally a comparatively low-strength material, there are no strict quality requirements for fly ash used in flowable fill or controlled low strength material mixtures. Fly ash is well suited for use in flowable fill mixtures. Its fine particle sizing (nonplastic silt) and spherical particle shape enhances mix flowability.

6. Self-healing material - Wikipedia

   en.wikipedia.org/wiki/Self-healing_material

   Upon cracking, these particles are exposed to oxygen, and in the presence of heat, they react to form new materials which fill the crack gap under volume expansion. [123] This concept has been proven using SiC to heal cracks in an Alumina matrix, [ 124 ] and further studies have investigated the high temperature strength, [ 125 ] and the static ...
