| Abstract: | An experimental investigation on mechanics characteristics,such as compressive strength and plastic modulus,and shrinkage of high strength concrete at early ages is presented.The effects of the initial drying age on compressive strength,Young's modulus and shrinkage including autogenous and drying shrinkage are discussed.Further,the contribution of autogenous shrinkage and drying shrinkage strain to total strain is evaluated. |

| Keywords: | high strength concrete early mechanics characteristics autogenous shrinkage drying shrinkage initial drying age |
