Chloride migration in PPF concrete under dry-wet cycle

Abstract

In order to study the Clpenetration depth in polypropylene fiber concrete with different volume, indoor artificial method was used to simulate dry-wet cycle, and the concentrations of AgNO 3 solution indicator on the Clconcentration at the color change boundary of the specimens was investigated. The results indicated that the chloride penetration depth increased as the cycles of dry-wet was increased, adding 0.1%
