“…In the existing literature, there are many studies that assess the potential of different types of slag from the production and refining of various metals to substitute sand in concrete. Possible such substitutes are steel slag (Rahmawati & Saputro, 2018), slag from the refining of lead and zinc (Tripathi & Chaudhary, 2016), and rapid cooling electric arc furnace oxidizing slag (Kim, Koh, & Pyo, 2016). Other industrial wastes, such as palm oil clinker, coal bottom ash (Ong, Mo, Alengaram, Jumaat, & Ling, 2018), fly ash (Rafieizonooz et al., 2017), fixated phosphate industry waste (Lieberman et al., 2018), and waste from granite and marble processing (Singh, Tiwari, Nagar, & Agrawal, 2016) can also be used to partially replace sand.…”

“…La escoria de acero puede verse como una alternativa potencial de agregados naturales y así ahorrar una gran parte de recursos naturales y proteger el medio ambiente (Rahmawati y Saputro, 2018). En Malasia, el vertido de escoria de acero es el método de eliminación más convencional, debido a esto, no solo causa escasez del vertedero, sino que el medio ambiente se verá afectado (Lim, Chew, Choong, Tezara, y Yazdi, 2016).…”

La presente investigación se basó en la innovación y elaboración de una mezcla asfáltica en caliente (MAC), debido al deterioro prematuro de los pavimentos flexibles, y poca capacidad de cumplir con su vida útil. He aquí la necesidad de asegurar una buena calidad de materiales para la mezcla asfáltica y una búsqueda de nuevo material que sea capaz de dar mayor durabilidad y evitar un prematuro deterioro del pavimento. Se evaluó así la incorporación de escoria de acero para el diseño de MAC, con el objetivo de determinar la estabilidad y flujo de la mezcla asfáltica en caliente incorporando escorias de acero. Para esto, se empleó la metodología Marshall con un porcentaje de escoria de acero respecto al agregado grueso en 0% - 15% - 25% - 50% - 75%. Los resultados obtenidos, en cuanto a calidad de los agregados, cumplieron con los estándares de calidad. Se concluyó que la mezcla asfáltica modificada con la escoria de acero al 15% es la mejor combinación, de igual forma, este porcentaje cumple para tránsito liviano, mediano, al 25% - 50% - 75% solo cumplen para transito liviano. Se logró aumentar la estabilidad y flujo de la mezcla asfáltica al incorporar hasta un máximo de 25% para una MAC respecto a la mezcla de control.

To investigate the compressive behavior of steel slag fine aggregate concrete (SSC) under impact loading, the normal concrete and steel slag fine aggregate concrete with varying steel slag fine aggregate (SSA) contents were prepared and a Split Hopkinson Pressure Bar (SHPB) with a diameter of 100 mm was used for the dynamic compression testing under various strain rates. The microstructure characteristics of concrete specimens were observed by scanning electron microscopy to investigate the impact behavior changes mechanism of SSC under dynamic loading. The research results indicate that the compressive strength, DIF, and impact toughness of the specimens exhibit significant strain rate effects, all of which increase with the increase of strain rate. At similar strain rates, both impact toughness and dynamic compressive strength show an upward trend with the increase of steel slag content, while DIF decreases with the increase of steel slag content. The microstructure of SSC is denser, and the hydration product of SSA fills the internal defects of concrete and significantly enhances the interface transition zone (ITZ) between fine aggregates and cement matrix, which has an enhancement effect on impact toughness and the dynamic compressive strength of concrete. The empirical formulas were proposed based on the testing results to predict the DIF of SSC with various SSA contents. The compression constitutive models considering strain rate and steel slag content of SSC were established, and the fitting consequences with the test results accord rather well.
