Abstract

Applying the X-ray diffraction technique, we have investigated the dependence of the residual stress components on ettringite crystals in expansive cement paste depending on the content of ye’elimite admixture. The results of above stress analysis were used to analyze how the shrinkage-compensating effect and the content of ye’elimite admixture are correlated with each other.
