Determination of the reinforced concrete strength by

Uniaxial compressive strength is a direct method for the determination of concrete strength. However, this process gives damage to the structure. According to the validity standards, uniaxial compressive strength is determined by taking various sizes core samples from the existing structure.

Experimental Study of Concrete Early Creep

Lying-tensile concrete creep dev was designed, and the dev was used at the early age of concrete in measuring the tensile elastic modulus, creep and tensile strength. Meanwhile, the using of the dev to determine the parameters has been authenticated. Tests show that the usage of the dev not only can determine the early age of concrete creep, elastic modulus, but also can maintain
