文摘
- •
Effect of different sizes of nano-SiO2 particles on HPC properties was investigated.
- •
By decreasing w/b ratio, coarser nano-SiO2 improved mechanical properties of HPC more than finer type.
- •
Finer nano-SiO2 showed higher pozzolanic activity than coarser nanoparticles.
- •
Probability of nano-SiO2 agglomeration was increased by using finer type.
- •
Coarser type of nano-SiO2 led to a finer pore structure compared to finer particles.
