What's the use of water residue? Where is the special slag powder?

Special high-quality and stable water slag resources are used, and no grinding AIDS are added in the production, so that special slag micropowder has stable chemical components that other mixed materials (such as fly ash and stone powder) do not have. ) can't compare. The S95 grade mineral powder produced conforms to the national standard GB/T 18046-2008 "Blast Furnace Slag Powder for Cement and Concrete", and has passed the inspection by Hebei Product Quality Supervision and Inspection Institute and Hebei Water Conservancy Engineering Quality Inspection Center. As the sixth component of concrete-mineral admixture, slag powder can replace cement in the same amount and be directly mixed into commercial concrete. According to the difference of activity and specific surface area, the dosage is generally 20 ~ 40%. The performance of concrete mixed with slag powder is obviously improved, and it has the following advantages:

① It is easy to control the rheology of concrete at the initial stage of mixing, improve the fluidity of concrete and have good pumping performance;

(2) reduce the hydration heat value;

③ Reduce the dosage of cement in concrete and improve the later strength of concrete;

④ Strong sulfate resistance, because the content of C3A in concrete mixed with slag powder decreases, correspondingly, the content of Ca(OH)2 decreases during hydration, so the sulfate resistance is enhanced;

⑤ Anti-alkali aggregate reaction;

⑥ Anti-miniaturization, strong adhesion with steel bars.

The above properties determine that slag micropowder is especially suitable for high-rise buildings, dams, airports, underwater and underground buildings and other special projects.
