Quantification of hydration products in cementitious materials incorporating silica nanoparticles

L. P. SINGH,A. GOEL,S. K. BHATTACHARYYA,G. MISHRA

Frontiers of Structural and Civil Engineering 2016, Volume 10, Issue 2,   Pages 162-167 doi: 10.1007/s11709-015-0315-9

Abstract: silica nanoparticles (30-70nm) were supplemented into cement paste to study their influence on degree of hydrationAs the hydration time proceeds, the degree of hydration reach to 76% in nano-modified cement paste whereasAn influence of degree of hydration on the porosity was also determined.is ~35 % only, it revealed that silica nanoparticles refines the pore structure due to accelerated hydrationThese studies reveal that the hydration mechanism of the cement can be tuned with the incorporation of
