特别的，与其他纳米材料不同的是，NS和NA不仅可以作为晶核在早期加速水

In particular, the other is different nanomaterials, NS and NA not only as a nucleating accelerating cement hydration at early hydration products may also be additional calcium hydroxide in the reaction with the pore solution, including hydrated silicic acid hydrated calcium aluminate and calcium, to form a more dense microstructure of [4], so that the concrete strength [5, 6] and [7 durability, 8] have been greatly improved

In particular, unlike other nanomaterials, NS and NA can not only be used as crystalcore to accelerate cement hydration in the early stages, but also produce additional hydration products with calcium hydroxide reaction in the hole solution, including, calcium hydroxinate and calcium hydrated, resulting in a denser microstructure, making concrete strength . and durability . . . 7, 8 are greatly improved

In particular, unlike other nano materials, NS and Na can not only accelerate the hydration of cement in the early stage as crystal nucleus, but also react with calcium hydroxide in pore solution to generate additional hydration products, including hydrated calcium silicate and hydrated calcium aluminate, so as to form a more compact microstructure [4], so that the strength [5, 6] and durability [7, 8] of concrete are very large Improvement<br>
