Table 4 Drying characteristics of the \( C\overline{S} A \) and portland cement pastes.

Mixture ID	Total % weight change	Day to equilibrium (less than 0.02 %/day)
\( C\overline{S} A \) 0.4^a	−9.9	24 days
\( C\overline{S} A \) 0.5	−15.3	24 days
\( C\overline{S} A \) 0.6	−20.3	24 days
PC 0.4^b	−15.9	50 days
PC 0.5	−21.7	50 days
PC 0.6	−26.0	41 days

^aThe mixture ID \( C\overline{S} A \) 0.40 stands for the \( C\overline{S} A \) cement pastes or concrete with a water-to-cement ratio of 0.4.
^bThe mixture ID PC 0.40 stands for the portland cement pastes or concrete with a water-to-cement ratio of 0.4.
