Resumo
The influence of titanium dioxide powders obtained from the waste sorbent produced when discharges with nonferrous heavy metals are purified on the main technical properties and processes of structure formation of Portland cement stone was studied. It is shown that titanium dioxide modified with nanodispersed powder added to the cement composition plays the role of a modifier accelerating processes of hydration and hardening of cement. In the presence of titanium dioxide, the cement stone acquires the capability of self-purification owing to photocatalytic activity of the introduced additive.
