EAF Slag

Description

1. Product Overview

EAF Slag (Electric Arc Furnace Slag) is a high-strength, steelmaking by-product generated during the electric arc furnace process. Rich in iron oxides, calcium silicates, and other stable mineral phases, it is widely utilized as a durable aggregate and secondary raw material in construction, cement, and metallurgical applications. Its superior hardness, abrasion resistance, and volumetric stability make it a high-performance alternative to natural aggregates. As industries increasingly prioritize resource efficiency and circular economy practices, EAF slag represents a strategically important solution for sustainable infrastructure development and cost-effective material sourcing.
