当引入一种纳米材料的时候可以显著提试件的高抗压强度，但是当同时引入两种

When introducing a nanomaterial time significantly increase the compressive strength of the test piece, but when the simultaneous introduction of two kinds of nanomaterials as effective as the introduction of a single nanomaterial, which is for two nanomaterials have a high the specific surface energy, agglomeration occurs in the mixing process, resulting in improvement NSA1 system of reduced strength.

When the introduction of a nanomaterial can significantly raise the high pressure strength of the test piece, but when the introduction of two nanomaterials at the same time the effect is not as good as the introduction of a single nanomaterial, this may be because both nanomaterials have a high surface energy, in the mixing process of reunion, so the NSA1 system on the strength of the improvement effect is weakened.

When a nano material is introduced, the high compressive strength of the test piece can be significantly improved, but when two nano materials are introduced at the same time, the effect is not as good as that of a single nano material, which may be because both nano materials have high specific surface energy and agglomerate during the mixing process, so the effect of nsa1 system on strength improvement is weakened.
