Concretes Containing Hematite for Use as Shielding Barriers

Hematite was prepared as aggregate by crushing and grounding the ore in a laboratory mill, then sorting it via sieves into two groups of coarse (H c) and fine (H f) aggregates. Specific gravity, water absorption and loose unit weight were determined according to ASTM C 127, ASTM C 128 and ASTM C 129 standards.
