Exploring the influence of SiO2 and TiO2 nanoparticles on the mechanical properties of concrete
Abstract
Abstract The compressive strengths of concrete containing different contents of nano-SiO2 and nano-TiO2 have been investigated at ages of 3, 7, 21 and 28 days. Scanning electron microscopy and X-ray diffraction are used to evaluate the hydration products and paste-aggregate interface. The results indicate that both nano-SiO2 and nano-TiO2 can act as crystallization centers of calcium hydroxide and as fillers in the empty space, reduce the size of crystal at the interface and improve the compressive strength at 28 days. Also, both of them can react with calcium hydroxide, but only nano-SiO2 can produce C-S-H and enhance the early strength.

In the citing paper
“The increase in compressive strength with 2.5% of nps-TiO2 is attributed to nps-TiO2’s non-reactive fine filler properties, which reduced porosity, lacked pozzolanic activity, and played a significant role in ensuring cement matrix homogeneity [22,37,38,39,40,41].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
