Abstract:Self-consolidating concrete (SCC) is a relatively new approach to makingconcrete and is characterized by its high flowability and resistance to aggregatesegregation in the plastic state. SCC has become a popular alternative for commercialprecast elements and is being evaluated for use in precast bridge girders. This paperoutlines structural testing of six precast, pretensioned, AASHTO Type II girders. Threewere constructed using SCC, and three using a conventional mix. The major tasksincluded performing plastic and hardened property tests, constructing SCC beamswithout vibrating, determining the prestress transfer length, monitoring the camber,and finally testing the beams in such a manner as to produce flexure and sheardominated failure modes. Results of the construction and testing are presented.
