Theoretically, the higher the incorporation content of tire rubber to the concrete, the lower its resistance; however, this behavior was not observed for the TB2 pipe, which had the highest value among the pipes with rubber.
Teóricamente, a mayor incorporación de caucho de neumático en el hormigón, menor sería su resistencia; sin embargo, no se observó este comportamiento para el tubo TB2, que contenía el mayor valor entre los tubos con caucho incorporado.
