In fact, the addition of a proportion of 6% nano-silica is enough to attain marked increases in performance [43,46]. The incorporation of nano-silica affects mainly the process of hydration, which is sped up, fostering a greater production of calcium silicate hydrates as nano-silica reacts with the calcium hydroxide in the concrete.
Permanent deformation is pavement distress that has been the root cause of failure of roads globally. With the formation of a rut, follows cracking which inevitably damages the asphalt and sub-base layers. To curb the rutting distress, this study investigates the use of nanosilica, miniaturized silica particles to the power of 10-9 to modify the binder of the …

Peerapan Dittanet studied nano silica with different ranges of filler content, which are 23, 74, and 170 nm. The result shows that the value of Young's modulus K IC and G IC increased from the value of neat epoxy. The 170 nm size nano silica particles showed the highest Young's modulus among other size of nano particles.
