For this purpose cement grouts on the base of boron-containing LRW were prepared by:
- intermixing manually during 3 minutes for a comparison;
- intermixing manually during 1 minute with consequent treatment in the vortical mixer
with ferromagnetic particles, varying time of treatment.
From cement grouts we prepared samples and determined compression strength at vari-
ous terms of hardening. Samples were stored under humid air conditions.
