[1126] AN EXPERIMENTAL STUDY OF THE COMBINED EFFECT OF BINDER TYPES AND CURING METHODS ON CHLORIDE INGRESS UNDER ACTUAL ENVIRONMENTAL CONDITIONS

An onsite exposure test in airborne chloride environment has been conducted. After 3-month, 1.5-year, and 3.5-year exposure, the series of chloride penetration profile and carbonation depth of the specimens with different mixtures and several curing methods are shown. Stagnation of chloride ingress is observed in the SCM-containing concrete, whereas perpetual ingress is observed in OPC concrete. Longer curing by the highly water-repellent sheet provides higher chloride and carbonation resistance to concrete, and is effective when using with the SCMs, but provides less benefits in OPC in terms of chloride resistance.
