Experimental Study of Concrete Early Creep Determination by Using Lying-Tensile Creep Device
Lying-tensile concrete creep device was designed, and the device was used at the early age of concrete in measuring the tensile elastic modulus, creep and tensile strength. Meanwhile, the using of the device to determine the parameters has been authenticated. Tests show that the usage of the device not only can determine the early age of concrete creep, elastic modulus, but also can maintain constant loads without stabilized device. Study shows that under the same conditions, the ultimate tensile strength of the concrete which were measured creep should be lower than than that of non-creep of concrete. The earlier the loaded age, the greater decreased of ultimate tensile strength, it indicats that the creep of concrete has a certain weakening effect on concrete bearing strength.
