Resumen

En este trabajo se reportan resultados parciales derivados de una serie de experimentos de laboratorio, con los que se estudia el  empleo de caucho de llantas de desecho como agregado en concreto de cemento Portland, reemplazando el 10% en peso del agregado pétreo. Se estudiaron tres mezclas de concreto: simple, con caucho grueso y con caucho fino. Los tamaños de las  partículas del caucho grueso variaron de 6.32 - 9.53 mm, mientras que para el fino iban de 2.35 - 2.80 mm. La influencia de este material en la resistencia mecánica del concreto se evaluó mediante cilindros y vigas, a los 28 días de edad, bajo condiciones de carga uniaxial de compresión, tracción indirecta y flexión. Para las tres condiciones de carga estudiadas, los resultados  experimentales mostraron una reducción de la resistencia del concreto, cuando se sustituye parte del agregado pétreo con caucho. La mezcla de concreto con partículas finas de caucho presentó un mejor comportamiento mecánico que la mezcla con partículas gruesas; incluso en condiciones de flexión, la resistencia era casi igual a la del concreto simple.
