从图1（a）可以清晰的观察到，随着养护龄期的延长，标养环境下的砂浆的抗

It can be clearly seen from FIG. 1 (a) that, with increasing age of curing, the compressive strength of mortar under standard curing environment is increasing, and by introducing nano-alumina and nano-silicon oxide, is higher than the compressive strength not mixed system nanomaterials.

It can be clearly observed from Figure 1(a) that with the extension of the conservation age, the pressure resistance of the mortar in the standard environment is increasing, and through the introduction of nanosilica oxide and nanoaluminum, the pressure resistance strength is higher than the system without nanomaterials.
