摘要

PROBLEM TO BE SOLVED: To make it possible to accurately evaluate surface quality of concrete with consideration of moisture dependence in results of a surface air permeability test.;SOLUTION: A method for evaluating surface quality of concrete includes: steps (S1, S2) of calculating an approximate linear expression showing the relation between electrical resistivity measurement values obtained by performing electrical resistivity measurement on concrete and material age; steps (S3, S4) of calculating an approximate linear expression showing the relation between surface air permeability coefficients obtained by performing a surface air permeability test on the concrete and the material age; a step (S5) of calculating a surface air permeability index by dividing a slope value of the approximate liner expression of the electrical resistivity by a slope value of the approximate liner expression of the surface air permeability coefficient; and a step (S6) of evaluating surface quality of the concrete by using the value of the surface air permeability index.;COPYRIGHT: (C)2013,JPO&INPIT
