Application Research of Method of Noumenon Sampling Detection in Strength Test on Structural Concrete

Noumenon sampling, a new detection technology for strength of structural concrete, is proposed.The conversion relationship between the strength of noumenon sampling specimen and the strength of standard maintenance specimen was explored by correction coefficient and regression analysis．the conversion coefficient for concrete strength between the standard curing specimen and the structural concrete was1.08, which is less than the specification of conversion coefficient(1. 10); therefore, the test result by noumenon sampling is more accurate and reliable.
