Abstract：The phase composition and micro-morphologies of hydration products of shrinkage-compen-sating mortar were investigated under the simulated condition of the core of massive concrete using semi-quantitative XRD and SEM-EDS. The cracking of mortars induced by delayed ettringite formation is due to the uniform expansion of rnicrocrystalline ettringite in the hardened mortars.
