Zeolita natural proveniente de Puebla como tratamiento de suelos de la región de Querétaro en vías terrestres: Efectos en su comportamiento plástico Antonio Hernández-Francisco Teresa López-Lara Juan Bosco Hernández-Zaragoza Jaime Moisés Horta-Rangel Ingeniería cal Zeolita natural límites de Atterberg clinoptilolita de Puebla mejoramiento de suelos Querétaro Las puzolanas naturales tienen fama de emplearse como materiales puzolánicos de origen natural desde hace mucho tiempo, y es uno de los compuestos principales en la fabricación de concretos de alta resistencia. Como material de construcción, su uso ha sido explorado en la estabilización de suelos, haciendo necesaria la adición de cal a la mezcla para llevar a cabo la activación puzolánica y que la formación de cristales cementantes se lleve a cabo. Sin embargo, factores como pH del suelo, intercambio catiónico, hume- dad natural y mineralogía del suelo afectan en gran medida la cantidad de cal libre con la que puede combinarse la zeolita y realizar su actividad. Como consecuencia, para la estabilización de algunos suelos es necesario utilizar productos químicos más complejos cuya obtención implica diversos problemas ambientales y económicos. Por ello, el siguiente trabajo tiene como propósito la evalua- ción de diferentes cantidades de zeolita en la estabilización de un suelo expansivo utilizando cal como activador puzolánico, eva- luando las propiedades índices del suelo estabilizado y la relación de los porcentajes implicados. Los resultados de las pruebas realizadas en la muestra de suelo arcilloso expansivo (CH) indican que la dosificación óptima de cal-zeolita es de 10-6 % respectiva- mente, obteniendo valores de: Límite Líquido (LL)=55.25, Límite Plástico (LP) =46.1, Límite de contracción (LC)=31.86; con un promedio de disminución del Índice Plástico (IP) de 33 % respecto a los límites del suelo natural. En virtud de los resultados, se concluye que el uso de cal y zeolita natural resulta favorable para la estabilización de arcillas en la región de Querétaro. 2021 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40471798008 https://www.redalyc.org/journal/404/40471798008/ https://www.redalyc.org/journal/404/40471798008/html/ https://www.redalyc.org/journal/404/40471798008/40471798008.epub https://www.redalyc.org/journal/404/40471798008/movil 10.14482/INDES.30.1.303.661 es http://www.redalyc.org/revista.oa?id=404 Ingeniería.
