Experimental Study of Slag Powder Fineness Effect on Concrete Performance

Abstract:

Slag powder can improve concrete compression strength and durability owing to the activity of volcano ash and powder filling effect when replacing cement as active mineral admixture. Test results show that the 28-day strength can reach to 74MPa if slag powder with the fineness 810 m²/kg is used to replace 60% cement when making C40 concrete. And at 4.0MPa water pressure, the seepage height can be only 12mm, the electric flux in 6 hours can drop by 72% than that didn't use slag powder, the ability of freeze-thaw cycle can reach F350. But attention should be paid to the grinding process impact on the economy of the massive practical application process.
