Santamaría, Amaia Ortega López, Vanesa Skaf Revenga, Marta Chica Páez, José Antonio Manso Villalaín, Juan Manuel 2020-03 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. application/pdf http://hdl.handle.net/10259/5295 eng Elsevier The study of properties and behavior of self compacting concrete containing Electric Arc Furnace Slag (EAFS) as aggregate info:eu-repo/semantics/article TEXT RIUBU.
