Problems solved by technology

However, the damage degree, damage process and repair effect of reinforced concrete are far from meeting the requirements only by appearance observation. It is necessary to use advanced physical and chemical means to detect its state, evaluate its "health", and predict its remaining life

Embodiment Construction

[0040] 1. Design of mathematical model for remaining life prediction

[0041] The mathematical model establishes the corresponding relationship between electric flux and chloride ion diffusion coefficient through regression prototype observation, exposure test and indoor test; quantitative calculation is carried out by using relevant model parameters. As shown in Table 1, it is a list of basic mix proportions of high-performance concrete.

[0044] Note: w / b—water-cement ratio, b coagulation material, F1-I grade fly ash, F2-II grade fly ash, S—silica fume, K—mineral powder, the symbols in the mixing ratio of the following contents are the same as this .

[0045]SL in the table refers to slump

[0046] As shown in Table 2, it is the test result of high performance concrete resistance to chloride ion penetration.

Abstract

The invention discloses a concrete structure life prediction system, consisting of a concrete structure durability parameter measuring system, a concrete structure residual life calculation analysis system and an early warning system. Comprehensive evaluations parameters of the quality of a concrete protective layer and steel bar surface state conditions are measured through the parameter measuring system and are calculated through the concrete structure residual life calculation analysis system. Early warning instructions are sent out by the early warning system. The invention integrates computer hardware and software, a concrete structure durability research, an electrochemical technique, an intelligent sensor technology, a wireless network digital technology, a data acquisition analysis, etc. The practical operation is simplified and the working efficiency is improved.

Description

technical field [0001] The present invention relates to a set of system flow design capable of remotely monitoring the durability parameters of concrete structures in service, issuing early warnings on whether the durability limit is healthy or not by wireless network remote transmission, and calculating and analyzing the remaining service life of concrete structures through computer program software . Background technique [0002] Marine concrete structures such as ports, roads and bridges in the marine environment, due to the corrosion of chloride salts, cause steel bar corrosion, which is recognized as the most important cause of concrete structure damage, and the resulting concrete structure damage has become a worldwide phenomenon. A major disaster of widespread concern and growing prominence. The direct and indirect losses caused by steel corrosion damage are far beyond people's expectations, and have constituted a serious financial burden in developed countries in Eu...
