Estudio del comportamiento de hormigones de muy alta resistencia sometidos a cargas de choque térmico
This paper analyses the mechanical behavior of very high strength concrete, reinforced with fibers, after being exposed to thermal shock loads. Two types of concrete are analyzed, one without any fiber (control concrete) and another reinforced with steel and polypropylene fibers. These concretes have undergone a heating process up to 300°C and have cooled in different ways, from slow cooling inside the oven to rapid cooling in water. In this way, the influence of the application speed of cooling loads on their mechanical properties is analyzed.
