The present work assessed the feasibility of applying blasted copper slag (BCS) as addition to cementitious composites. Series with 0-15% of BCS were produced and characterized by compression strength, durability, spread and specific gravity. In fres

The modulus of elasticity of concrete is often calculated as a function of the compressive strength, and as a deterministic value. However, variations in the aggregates properties may result in module values different than those estimated, which may
