Studying concrete modification using nano-composite particles
Continuing Education Institute of Hefei Vocational and Technical College, Hefei, China
The methods of concrete modification are described in the article. The effects of TiO2 nanoparticles on the hydration, mechanical properties and durability of the cement matrix were studied. The results showed that the addition of TiO2 nanoparticles increased the moisture of the concrete in the early stages; that made the concrete denser, increased the homogeneity of the elements distribution and caused 14 % increasing the strength under pressure.
