Khoom nta:

Cov khoom siv cement-raws li ib txwm muaj lub zog tsawg, thiab ntxiv qee qhov ntawm nano-silica tuaj yeem txhim kho kev ua tau zoo ntawm pob zeb.

Daim ntawv thov rau pob zeb txhawm rau txhim kho lub zog:

1. Ntxiv nano-SiO2 rau cov cement mortar tuaj yeem txhim kho cov compressive thiab flexural zog ntawm cement mortar ntawm ntau lub hnub nyoog.
2. Nws tuaj yeem txo qhov poob qis thiab nthuav dav ntawm pob zeb.
3. Nws tuaj yeem ua rau autogenous shrinkage strain ntawm pob zeb;
4. Nws tuaj yeem txhim kho qhov kev hloov pauv ntawm cov qauv sib txuas ntawm kev sib sau ua ke thiab muab tshuaj txhuam hauv pob zeb.

Kev pom zoo ntxiv tus nqi: 2-5% lossis nyob ntawm qhov xwm txheej tiag tiag.
