Khoom Description

Silica fume tuaj yeem siv los ua cov khoom siv cementitious ntxiv rau hauv cov pob zeb, tshwj xeeb tshaj yog nyob rau hauv nws tus kheej consolidating pob zeb, vim nws cov khoom tshwj xeeb xws li kev ua haujlwm siab pozzolanic, txhim kho kev ua haujlwm, muaj zog thiab ua haujlwm ntev. Nws qhov me me me me tso cai rau nws los sau qhov sib txawv ntawm cov cement particles, txhim kho cov ntim ntom ntom, txo cov porosity, thiab ua kom lub zog ntawm cov cement matrix. Tsis tas li ntawd, silica fume reacts nrog calcium hydroxide los tsim ntxiv calcium silicate hydrate (CSH) gel, uas txhim khu lub zog, durability, thiab tshuaj tiv thaiv ntawm cov pob zeb. Silica fume kuj txo cov permeability ntawm pob zeb, uas ua rau nws tsis tshua muaj kev puas tsuaj los ntawm khov-thaw cycles, acid nres, thiab chloride ion nkag mus.
