Mineral slag micro powder and preparation method thereof
The invention discloses a mineral slag micro powder and a preparation method thereof. The mineral slag micro powder is composed of following raw materials, by weight, 75-85% of blast furnace slag, 5-15% of coal slag and 10% of fly ash. The mineral slag micro powder can greatly improve strength of cement concrete, can be used for preparing ultrahigh-strength cement concrete, can effectively improve the anti-erosion performance of the cement concrete and is especially suitable for anti-corrosion engineering. The mineral slag micro powder can significantly reduce water bleeding and improve workability of the cement concrete, can significantly improve the compactness and the anti-permeability of the cement concrete, can significantly hydration heat of the cement concrete, and is suitable for preparing large-volume concrete. The mineral slag micro powder can effectively inhibit an alkali-aggregate reaction of the cement concrete, can significantly improve the performance of alkali-aggregate reaction resistance of the cement concrete and can improve the durability of the cement concrete.
