Micro silica yog siv dav hauv pob zeb, uas ua rau cov pob zeb muaj zog dua compressive, dej tsis kam thiab tshuaj lom neeg.Qhov no tuaj yeem txo cov nqi khoom siv thiab kev siv hluav taws xob.Cov ntaub ntawv tshiab nano, xws li nano silica lossis nanotubes, ua rau kev txhim kho ntxiv ntawm kev tiv thaiv thiab lub zog.Nano silica hais los yog nanotubes tau hloov mus rau hauv nano cement hais nyob rau hauv cov txheej txheem ntawm pob zeb solidification.Cov khoom me me ua rau luv luv particle nrug, thiab cov khoom siv nrog qhov ntom ntom dua thiab tsawg porosity.Qhov no nce lub zog compressive thiab txo cov permeability.Txawm li cas los xij, ib qho ntawm qhov tsis zoo ntawm nanopowders thiab cov ntaub ntawv yog tias lawv yooj yim rau kev sib sau ua ke thaum ntub thiab sib tov.Tshwj tsis yog tias tus neeg hais tawm tau zoo dispersed, caking yuav txo qhov cuam tshuam qhov chaw, uas ua rau degradation ntawm pob zeb ua haujlwm.
