    Durante el a\u00f1o 2006, la empresa administradora Chungar del grupo VOLCAN, tom\u00f3 la decisi\u00f3n de construir losas en los talleres de mantenimiento de maquinaria pesada. Debido a las grandes cargas de la maquinaria pesada que transitar\u00eda en el taller, era necesario dise\u00f1ar una losa de concreto armado. Este proyecto consist\u00eda no solo de todas las losas que formaban parte del taller; sino tambi\u00e9n, de las rampas de acceso que este tendr\u00eda. El tr\u00e1nsito de estos talleres ser\u00eda muy considerable debido a la magnitud de la mina. 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. 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 4,900 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\u00ae<\/b>. La soluci\u00f3n original era de una losa convencional de 25 cm de espesor en concreto simple. 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\u00ae<\/b> FF1 por m\u00b3 de concreto. Con el gran desempe\u00f1o de las fibras de acero en el concreto se logr\u00f3 reducir 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>
