The Influence of Super-Fine Steel Slag on the Properties of High-Strength Concrete

Abstract:

The properties of the concrete with super-fine steel slag were compared with those of the pure cement concrete. Results show that the concrete with 20% super-fine steel slag has similar compressive strength, elastic modulus, and permeability with the pure cement concrete at the age of 28 and 90 days. The addition of super-fine steel slag tends to decrease the initial slump of concrete, but it has a good ability of prevention of slump loss. The concrete with super-fine steel slag has similar anti-carbonation capacity with the pure cement concrete. The concrete with 30% super-fine steel slag has lower compressive strength, lower elastic modulus, and higher permeability than the pure cement concrete.
