Size Effect of Concrete Compressive Strength with Different Reinforcement Ratio
An experimental investigation is reported into the size effect for compressive strength from 36 concrete prism specimens under axial loading and with three different kinds of dimensions of 100×100×300mm, 150×150×300mm, 200×200×400mm. Such parameters as strength grade of concrete and reinforcement ratio are taken into consideration. Three different strength grades of concrete and two different reinforcement ratio are included in those specimens, all tests are undertaken according to ASTM C 39/C 39M-2005. Based on the results obtained, a new size effect law for different kinds of concrete in prismatical compressive strength is suggested and those relative parameters on the size effect are discussed.
