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: work, silica nanoparticles (30-70nm) were supplemented into cement paste to study their influence on degreeof hydration, porosity and formation of different type of calcium-silicate-hydrate (C-S-H) gel.As 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.These studies reveal that the hydration mechanism of the cement can be tuned with the incorporation of

Understanding the behavior of recycled aggregate concrete by using thermogravimetric analysis

Subhasis PRADHAN, Shailendra KUMAR, Sudhirkumar V. BARAI

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 6,   Pages 1561-1572 doi: 10.1007/s11709-020-0640-5

Abstract: A method is proposed to estimate the degree of hydration ( ) from chemically bound water ( ).concrete mixes with different aggregate type and mix design method as the present study confirms that the degreeof hydration is not the only parameter which governs the macro-mechanical properties of concrete.

Analysis of synergy degree and its influencing factors in hydropower EPC project management

Jiwei ZHU, Hua GAO, Jiangrui WANG

Frontiers of Engineering Management 2021, Volume 8, Issue 3,   Pages 402-411 doi: 10.1007/s42524-020-0098-0

Abstract: The mechanism and factors that influence the degree of management synergy are analyzed on the basis ofanalysis is utilized to identify the key factors that affect the synergy degree.Results show that the order degree of each subsystem presents a steady upward trend.Specifically, the order degree of the subsystem at the trial operation stage is low, which is the majorrestriction on the further improvement of the synergy degree of EPC project management.
