Hace ya algunos a\u00f1os, la empresa DOE RUN ha iniciado los trabajos de pavimentaci\u00f3n de todas sus labores, tanto en la planta de Fundici\u00f3n como en Refiner\u00eda. Las cargas que recibir\u00e1n estos pavimentos es la de los volquetes que transportan el mineral y que llegan a tener m\u00e1s de 30 ton de carga bruta. Adem\u00e1s, parte de la losa servir\u00eda como parte de la estructura del tren de transporte de mineral. Es de conocimiento general, que las obras en mina deben tener el m\u00ednimo tiempo de ejecuci\u00f3n posible para no perjudicar la extracci\u00f3n de los minerales y, por consecuencia, no comprometer el rendimiento. Por ello, era necesario que la losa tenga un procedimiento constructivo bastante sencillo y r\u00e1pido. Adem\u00e1s de las grandes cargas a las que estar\u00eda expuesto este pavimento, se tendr\u00edan las condiciones clim\u00e1ticas presentes a 4,800 m.s.n.m, donde se presentan temperaturas de -5\u00baC por la noche y de 25\u00baC en el d\u00eda.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Para obtener un alto rendimiento en la ejecuci\u00f3n de la obra y una larga vida \u00fatil de la estructura en condici\u00f3n de servicio; se present\u00f3 una propuesta consistente en una losa de concreto que inclu\u00eda el uso de fibra de acero Wirand. La soluci\u00f3n propuesta consist\u00eda de una losa de concreto de 20 cm de espesor con una dosificaci\u00f3n de 25 kg de Wirand FF1 por m\u00b3 de concreto. Con el gran desempe\u00f1o de las fibras de acero en el concreto se logr\u00f3 optimizar los espesores de la losa obteniendo un sustancial ahorro en el proyecto, y tambi\u00e9n se mejor\u00f3 la performance reflejada en mayor resistencia a la abrasi\u00f3n, al impacto y a la fatiga. La asesor\u00eda t\u00e9cnica durante la elaboraci\u00f3n del expediente y ejecuci\u00f3n de la obra fue realizada por Maccaferri de Per\u00fa.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
