The SCBA used in this research was chosen based on a previous study [21],
where low-energy consumption post-treatment methods, including sieving and
grinding, were implemented; furthermore, different cement replacement and curing
times were evaluated at different ages. The Strength Activity Indexes (SAIs),
which is an indication of the pozzolanic activity of the SCBA using the ASTM
C311-04 recommendations, were determined [28]. From that work, it was found
that according to the SAIs values the most effective and less energy demanding
treatment was sieving the material through #200 sieve. It was also found that
by adding 10% of SCBA cement replacement, the SAIs obtained for all the mixtures
were much higher than 75%, even for early ages (Table 4) [29]. Based on
this, it was decided to use only 10% of SCBA for the soil stabilization in the present
study.
