There exists a mutual influence and mutual promotion relationship between the fluidity and strength of Ewende silica fume, as follows:

 

Effect of fluidity on strength

 

- Better filling: good fluidity makes the silica fume can be distributed more evenly in concrete and other materials, better fill the gaps between cement particles, reduce porosity, make the material structure more dense, so as to improve the strength.

 

- Improvement of construction performance: Good fluidity facilitates construction operations such as mixing, transportation, pouring and vibration of concrete, which ensures that the concrete is fully compacted and shaped during the construction process, avoiding internal defects due to construction difficulties and thus improving the overall strength of concrete.

 

Effect of strength on fluidity

 

- Structural optimization: Silica fume participates in the hydration reaction of cement, and the generated hydration products make the internal structure of the material more dense and stable. This optimized structure is to a certain extent conducive to maintaining better fluidity, because the stability of the structure can prevent excessive agglomeration or clogging between the particles, so that the material in the flow process more smoothly.

 

- Enhanced water retention: As strength increases, the water retention properties of the material usually improve. The gel formed by silica fume and cement hydration products adsorbs and retains water, reducing water loss and thus keeping the concrete somewhat wet for a longer period of time, helping to maintain its flowability.
