Second, graphical comparisons were conducted to illustrate
the statistical analysis results. Figures 3-22 and 3-23
show graphical comparisons of the coarse and fine aggregate
properties, respectively, determined using the four soaking
methods. The effect of the soaking methods on the measured
properties was more profound for Gsa and water absorption
results. For each measured property, the effect was more significant
for more absorptive and vesicular aggregates, especially
the BF slag material. However, the effect of the soaking
methods on the test results for fine aggregates was less significant
compared to that for the coarse aggregates, likely because
the fine aggregates have less connected voids than the coarse
aggregates. The effect was more significant for water absorption
but less profound for the other measured properties.
