“…Sorption test results indicated significant reduction in water uptake by samples constituted using bacteria-containing solutions. Baltakys et al (2014) studied the effect of gyrolite substituted with cadmium ions on the hydration kinetics of OPC at early stages. Since their solubility minima tend to be at elevated pH values, a cement pore solution provides an attractive environment in which hydroxides of toxic elements can be sequestered.…”
