Abstract:
Many investigations on self-consolidating concrete (SCC) have been carried out in the last several years and the mechanical behavior of this type of concrete is well understood by now. The fire behavior of this specialized concrete, however, is not fully understood, and contradictory results on the fire behavior of SCC were presented in the literature. Therefore, different types of SCCs with compressive strengths between 25 and 65 MPa (3.6 and 9.4 ksi) were designed, and specimens with an edge length of 300 mm were subjected to fire according to ISO 834 at an age of 180 days. The compressive strength at 28 days, the weight loss due to drying, the spalling of the specimens, and the residual compressive strength of the concretes after fire testing were measured and related to the performance of a reference vibrated concrete.
