Abstract

Abstract

By studying the relationship between early autogenous shrinkage and ultimate tensile strain of concrete, the influence laws of water-cement ratio and sand percentage on early autogenous shrinkage are analyzed. Research results show that the relationship between autogenous shrinkage at early ages and ultimate tensile strain can be approximately figured by a quadric equation. It is also demonstrated that autogenous shrinkage of concrete at very early ages increases evidently with the decrease of water-cement ratio and the increase of sand percentage.
