Blends contain sulfate resisting cement (SRC), micro silica (MS) and nano-sized TiO2 (nT) were prepared. The phase of nT is a pure anatase. Incorporating 5 wt.% of nT into cement blends gave more desirable physico-mechanical properties than others. The prepared mixes exhibited adsorptive action towards the hazard water-soluble xanthenes dye (pyronin Y, PY). The Delta G degrees of the PY contact with the nT-SRC/MS blend giving an estimate of -27.3 kJ. Adsorption capacity was calculated using UV-Vis spectroscopy. Contact time, pH and blend composition had an effect on the adsorption process. Blend surface is photoactive in the photomineralization of the adsorbed PY.
