Key points
- Fly-ash addition increases slag acidity (Mk) and viscosity (Mη) coefficients.
- Higher fly-ash content leads to a decrease in slag's hydrogen ion index (pH).
- Slag fiber stability improves with increased fly-ash ratio.
- A homogeneous solid solution forms above 8% fly-ash, beneficial for fiber production.

Abstract
AbstractThe impact mechanism of the modifying slag added fly-ash as a raw material preparation of slag fiber was studied. The results show that when the ratio of fly-ash increases, the acidity coefficient Mk and the viscosity coefficient Mη increase, but the hydrogen ion index pH decreases. In addition, the stability of the slag fiber increases at the same time. The viscosity of the slag decreases. The main crystalline phase of the slag is melilite. Air-cooled or water-cooled slag forms a homogeneous infinite solid solution when the ratio of fly-ash is above 8%. So it is conducive as a raw material of preparation of slag fiber.Keywords: FiberMineralSlagViscosity
