Buenas, tengo una duda si es que aplico un concreto de mayor resistencia en columnas (sus nucleos) al momento de hacer el vaceado de loza y que dicha resistencia es mayor ala de la loza verificando esto puede que exista algun problema o esta aprobado en alguna normal o regla?.

Saludos, el codigo ACI (American Concrete Institute) actualmente las reglas en los paises se basan a dicho codigo, no menciona que se debe analizar bien el cambio de resistencia de los diferentes concretos a utilizar en una construcción, ya que el coeficiente de retraccion es diferente y puede tener como concecuencia generar esfuerzos en dicho nudo, es mejor revisar la memoria de calculo.
