The invention provides an advanced prediction method for chloride ion permeability resistance of concrete based on water binder ratio monitoring. The method comprises the following steps: (1) preparing concrete test pieces of different water binder ratios, and determining the water binder ratios of the test pieces; (2) testingchloride ion diffusion coefficients of 28 d and 56 d periods of the concrete test pieces of different water binder ratios; (3) fitting the curve of the characteristic relationship between the determined water binder ratios and the chloride ion diffusion coefficients; (4) testing the water binder ratio of on-site mixed concrete, and on the basis of the characteristic relationship curve, calculating chloride ion diffusion coefficients of 28 d and 56 d periods of the on-site mixed concrete and obtaining prediction values of chloride ion diffusion coefficients; and (5) judging if the chloride ion permeability resistance of the concrete accords to the standard or design requirement. The method can predict the chloride ion permeability resistance of on-site casting concrete before casting, and adjusts timingly the concrete which do not meet the standard or design requirement, can avoid the potential economic loss arising from lag of conventional control methods.
