STEELMAKING SLAG EXCELLENT IN WEAR RESISTANCE WHICH IS CONDITIONED AS AGGREGATE FOR ASPHALT OR CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide steelmaking slag which is excellent in wear resistance and shows little loss in quantity through abrasion when used as an aggregate for asphalt or concrete.

SOLUTION: The steelmaking slag excellent in wear resistance shows≤15% loss in quantity through abrasion as the aggregate which is low as shown in the figure, and has a ratio of dicalcium silicate (2CaO-SiO2) content to P2O5content (2CaO-SiO2/P2O5) adjusted to≤90.
