Effect of curing condition on shrinkage reducing property of self-consolidating concrete with different expansive admixtures

Abstract

In accelerated bridge construction, self-consolidating concrete (SCC) shows great potential of application to fill the gap between the deck soffit and precast concrete girders with heavy reinforcement especially in precast construction . An experimental program was undertaken to evaluate the performance of SCC incorporating different expansive admixtures for filling distance between precast bridge deck panels and girders. The study aimed to investigate shrinkage reducing properties as well as wokability of proposed SCC mixture under different curing conditions (water, air-dry and sealed cure). A combination of tests including slump flow, J-ring, V-funnel flow time, L-box and static bleeding were also conducted to measure the workability as well as mechanical properties of developed SCC.
