Creep and shrinkage of self-consolidating concrete (SCC)

Self-consolidating concrete (SCC) has been used increasingly over the last two decades, especially in the pre-cast concrete industry because of its ability to consolidate without vibration even in congested areas. The development of SCC mixture design has been driven mostly by private companies who desired to utilize SCC's advantages and consequently there exists limited public information regarding the performance of SCC mixtures. The goal of this research is to establish the creep and shrinkage properties of several SCC mixtures. During the course of the research, a new testing apparatus was developed to correct inadequacies of the established measuring apparatus. The development of this new apparatus proved partially successful and several improvements are proposed. The creep and shrinkage data collected were not of sufficient quality and quantity to allow for a comprehensive evaluation of the mixtures. Further improvements to the test methodology are proposed.
