- •
SNPs shows its maximum nucleation effect at 8 h when the rate of product formation is high than the control.
- •
Maximum pozzolanic effect of SNPs observed at 24 h when the quantity of CH was lower than the control.
- •
∼25% addition C-S-H formed in the presence of SNPs at 24 h.
- •
More polymerized and well ordered crystalline C-S-H is formed in presence of SNPs.
- •
SNPs formed more compact and dense microstructure at 24 h which is responsible for the higher early age mechanical strength.
