Hoʻohana nui ʻia ka micro silica i ka ʻuala, kahi e loaʻa ai ka ikaika compressive kiʻekiʻe, ke kūpaʻa wai a me ke kūpaʻa kemika. Hiki i kēia ke hoʻemi i nā kumukūʻai waiwai a me ka hoʻohana ʻana i ka ikehu. ʻO nā mea nano hou, e like me ka nano silica a i ʻole nanotubes, ke alakaʻi i ka hoʻomaikaʻi hou ʻana i ke kū'ē a me ka ikaika. Hoʻololi ʻia nā ʻāpana nano silica a i ʻole nanotubes i nā ʻāpana sima nano i ke kaʻina o ka paʻa paʻa. ʻO nā mea liʻiliʻi liʻiliʻi e alakaʻi i ka mamao pōkole, a me nā mea me ke kiʻekiʻe kiʻekiʻe a me ka liʻiliʻi o ka porosity. Hoʻonui kēia i ka ikaika compressive a hoʻemi i ka permeability. Eia nō naʻe, ʻo kekahi o nā hemahema nui o nā nanopowders a me nā mea waiwai he maʻalahi lākou e hana i nā aggregates i ka wā e hoʻomaʻemaʻe a hui ʻia. Inā ʻaʻole e hoʻopuehu maikaʻi ʻia kēlā me kēia ʻāpana, e hōʻemi ka caking i ka ʻili o ka ʻili i ʻike ʻia, e hopena i ka hoʻohaʻahaʻa ʻana o ka hana ʻana.
