The hydrati.n of tri.alci.m alumi.ate （ C3A ） has a si.ni.i.ant effect on the effecti.eness of cement-based systems. i. addi.i.n, the carbonati.n of hydrati.n products of C3A i. parti.ularly i.portant i. respect of durabi.i.y performance. The present work i.vesti.ates the hydrati.n and carbonati.n reacti.ns of C 3A and the changes i.duced by the presence of the heavy metal i.ns such as Zn^2＋ , Pb^2＋ , Cu^2＋ and Cr^3＋ by X-ray di.frac- tometry （ XRD ）. Duri.g hydrati.n of C3A, gehleni.e hydrate, hydrogarnet , calci.m monoalumi.ate （ C4AHx ） and calci.m carboalumi.ate were detected i. C3A pastes except the Zn^2＋ doped paste, where hydrogarnet di. not form. The exami.ati.ns revealed that heavy metals coexi.ted wi.h gehleni.e hydrate, calci.m monoalumi.ate （ C4AHx ） and calci.m carboalumi.ate, i.hi.i.i.g the formati.n of hydrogarnet. Hydrati.g C3A was li.ble to be carbonated on exposure to ai. and carbon di.xi.e, especi.lly i. the presence of heavy metals, resulti.g i. the formati.n of carboalumi.ate and/or calci.m carbonate. The presence of heavy metals i.-fluenced the polymorphi.m of calci.m carbonate, ndi.ati.g that heavy metals could co-preci.i.ate wi.h calci.m to form a carbonate soli. soluti.n.
