可以得出纳米氧化硅和纳米氧化铝的加入可以提高水泥砂浆的抗压强度和抗折强

Added can be derived nano-alumina and nano-silicon oxide can be improved compressive strength and flexural strength of the cement mortar. This is mainly due to the pozzolanic activity of nano silica and nano alumina consumed hardening mortar holes calcium hydroxide solution, calcium silicate hydrate and generate additional calcium aluminate hydrate, the pores are filled, so that the microstructure more dense, it exhibits increased strength.

It can be concluded that the addition of nano-silicon oxide and nano-alumina can improve the pressure strength and folding strength of cement mortar. This is mainly due to the volcanic ash activity of nanosilica oxide and nanoaluminum oxide, which consumes calcium hydroxide in the perforated solution of the hardened mortar, generates additional calcium hydroxinate and calcium hydrated aluminum, fills the pores, makes the microstructure more dense, so it shows an increase in strength.
