• Abstract:
  Many agencies have adopted the standard tests for electrical ; indication of concrete’s ability to resist chloride ion penetration ; (AASHTO T 277 and ASTM C1202), commonly known as the rapid ; chloride permeability test (RCPT), in their specifications for qualification ; and acceptance and as a means of indirectly assessing ; the permeability of concrete mixtures. (See references 1–5.) ; Nevertheless, the RCPT is labor-intensive and costly and presents ; high variability.(3,6,7) ; Research studies have shown that the surface resistivity (SR) ; test (AASHTO TP 95) is a promising alternative to the RCPT. ; (See references ; 3, 6, 8, and 9.) Recently, some agencies have ; shown interest ; in replacing the RCPT with the SR test and have ; started implementation ; efforts.(3,8) However, none of the studies ; have included high-volume fly ash (HVFA) mixtures or mixtures ; containing ; fly ash and fine limestone powder.
