A Promising Additive Based on the TiO2–Bi2O3 System for Cement Compositions

One of the central tasks of the development of modern building materials science is the search, development and synthesis of new modifying components for cement composites that can provide traditional materials with new unique characteristics. The current environmental situation worldwide contributes to the fact that building materials must safe for nature, humans and animals. This article considers the possibility of using bismuth titanates as a fine additive to cement composites, which can provide traditional cement based materials with bactericidal properties, as well as the ability to self-cleaning due to the mineralization of organic and inorganic pollutants adsorbed on the surface of the material. During the experiment the additive was synthesized by citrate technology and introduced into the cement composition in the form of a stabilized suspension instead of mixing water. The optimal methods of processing to stabilize suspensions of bismuth titanates particles were studied, which is an important factor for achieving uniform particle distribution in the volume of the cement composite. There was an increase in compressive strength on the first and third days of hardening from 29 to 42 MPa (by 31, 38 and 45%) and from 53 to 70 MPa (by 28, 30 and 32%), respectively. At 28 days age the compressive strength increased from 83 to 97 MPa (by 2, 9 and 14%) compared with the control sample.
