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.
