Method and system for lossless measurement and concrete durability inference

The invention discloses a method and system for lossless measurement and concrete durability inference. The method comprises the following steps of 1, drawing a determined maturity-chloride ion diffusion coefficient characteristic relationship curve based on reinforced concrete of which raw materials and a raw material ratio are known, 2, embedding a maturity tester into concrete of an entity component and testing concrete maturity, and 3, according to the maturity-chloride ion diffusion coefficient characteristic relationship curve obtained by the step 1, reversely inferring concrete chloride ion diffusion coefficients corresponding to maturity values in different periods in the on-site test, comparing the chloride ion diffusion coefficients and standard or design requirements to determine if the concrete chloride ion diffusion coefficients under the on-site conditions satisfy the standard or design requirements so that concrete durability inference is realized. The system and method save time and labor, realize accurate inference of a reinforced concrete member chloride ion diffusion coefficient and do not damage a concrete member in the whole process.
