Experimental Study on Creep Behavior of Prestressed Concrete
In order to study the influencing factors and variation patterns of the creep performance of prestressed concrete, the creep deformation of concrete specimens caused by long-term constant pressure and the instantaneous elastic deformation at the initial moment of applying this load were measured through experiments. The creep coefficient is mainly related to water reducing agents and additives, and the creep coefficient of concrete with single addition of fly ash at the same age is higher than that of concrete with double addition of fly ash and slag micro powder. Therefore, current research has not revealed the variation pattern of creep in prestressed concrete structures and the mechanism of its impact on prestressed relaxation. The measurement values of concrete creep and elastic modulus provided in this paper can be used as a reference for engineering construction control.
