2. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   After an initial layer of calcite is formed on the crack walls and the surrounding concrete matrix becomes less rich in calcium ions, the transition to the so-called "diffusion-controlled crystal growth" occurs, which means that the Ca 2+ ions must diffuse through the concrete, and the CaCO 3 layer in order to reach the crack surface and ensure ...

3. 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 ...

4. 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 ...

5. Alkali–silica reaction - Wikipedia

   en.wikipedia.org/wiki/Alkali–silica_reaction

   Typical crack pattern of the alkali-silica reaction (ASR). The gel exudations through the concrete cracks have a characteristic yellow color and a high pH. The fatty aspect of the exudations imbibing the concrete porosity along the cracks is also a distinctive feature of ASR. The alkali-silica reaction as a chemical cycle process

6. Spackling paste - Wikipedia

   en.wikipedia.org/wiki/Spackling_paste

   Spackling paste or spackle is a putty used to fill holes, small cracks, and other minor surface defects in wood, drywall, and plaster. [1] [2] Typically, spackling is composed of gypsum plaster from hydrated calcium sulfate and glue.

7. 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.
