Moreover, all fiber reinforced geopolymer composites yielded a drying shrinkage of less than 400 microstrains and an abrasion resistance of less than 1 g.
This process results in polymerization shrinkage of less than 1% [1].
Lower shrinkage and less damage of internally cured mortar were also observed by Zou and Weiss (2014) and Zou et al. (2015) in two different studies.
Moduli of elasticity measured for selected mixtures were accurately predicted by the ACI equation, and shrinkage was less than predicted by typical models.
Despite this variation, across the eight evaluation studies we identified, evidence does suggest that more visible tags tend to be associated with greater reductions in shrinkage than less visible tags.
The results indicate that the RBCB has a slight expansion ratio during hydration process, and it has a much lower dry shrinkage ratio, less hydration heat and a more stable hydration process than P.S 32.5 cement.
On the first day, the control gel size was reduced to ~50% of the initial value, followed by gradual shrinkage to less than 20% on the fifth day.
When [Na+]o was increased by 175 mM to 300 mM, more than double the physiological level, the increase in [Na+]i (after correction for osmotic cell shrinkage) was less than 20 mM.
