Abstract—A new X-ray diffraction technique is developed, for the first time enabling the detection of internal
microstresses (of the II mode) developing in cement hardening structures in the course of their formation, and
macrostresses (of the I mode) caused by capillary forces during the removal of pore-confined water. Prospects
of the application of this method are demonstrated for estimating the effect of various factors on the quality of
cement materials.
