Article Preview

In order to effectively assess the concrete damage under sea water erosion environment, concrete prediction damage model was presented based on damage mechanical and the experimental test. The degeneration of tension strength of concrete was tested after dry-wet cycles. The fact is proposed that the degeneration of concrete is an interior damage evolving process. Freezing and thawing damage accumulation of concrete was analyzed based on the discrete grid with probability of stochastic method. Three-dimensional multi- parameters Weibull distribution model about concrete damage evolutions were presented. Parameters were estimated based on gradient method. The mathematical model was verified using measured data. Corresponding algorithm was designed to establish concrete durability prediction model under sea water chemical erosion conditions. The research can be referenced for prediction of frost damage of concrete.
