Quartz sand was a mixture of three fractions (0.0/0.5 mm, 0.5/1 mm, 1/2 mm) that were mixed in the mass ratio 1:1:1. Similarly, zeolite was mixed from three fractions, 0.063/0.5 mm, 0.5/1 mm, and 1/2 mm, respectively. The mixing ratio was 1:1:1 by mass. The binder-to-aggregate volume ratio was 1:1.15 and was similar for all studied mortars.
