The study of properties and behavior of self compacting concrete containing Electric Arc Furnace Slag (EAFS) as aggregate Santamaría, Amaia Ortega López, Vanesa Skaf Revenga, Marta Chica Páez, José Antonio Manso Villalaín, Juan Manuel Electric arc furnace slag Self-compacting concrete In-fresh properties Long-term hardened properties Sustained load testing Materiales de construcción Building materials Electric Arc Furnace Slag (EAFS) can be efficiently reused as aggregate in the production of high-volume batches of hydraulic concrete mixes that show interesting properties in both the fresh and the hardened state. Mixtures containing EAFS aggregate in proportions of nearly 50% by volume are prepared for use as pumpable and self-compacting mixes with consistency classes of S4 and SF2, respectively. Characterization of the mixtures is presented, examining practical aspects such as thixotropy, segregation in the fresh state (under 6%), and mechanical and microstructural evolution in the hardened state. The results yielded compressive strengths of approximately 60 MPa and elastic moduli of 38 GPa after one year. Finally, real-scale flexural elements are cast and subjected to sustained loading tests of moderate intensity. Long-term deflection values were approximately 50% (pumpable mixes) and less than 40% (self-compacting mixes) of the maximum admissible values specified in current standards.
