Dab tsi additives ntxiv dag zog rau mortar?

Portland Cement: Raws li ib feem tseem ceeb ntawm mortar, Portland cement pab txhawb rau nws lub zog. Nws hydrates los tsim cov cementitious compounds, khi cov aggregates ua ke.
Txiv qaub: Cov tshuaj mortar feem ntau suav nrog txiv qaub, uas txhim kho kev ua haujlwm thiab plasticity. Txiv qaub kuj pab txhawb rau mortar tus kheej-kho cov khoom thiab ua rau nws tiv taus huab cua.

Silica Fume: Cov khoom siv ultrafine no, cov khoom siv ntawm silicon hlau ntau lawm, yog qhov muaj zog heev thiab txhim kho mortar lub zog thiab ua haujlwm ntev los ntawm kev sau cov voids thiab txhim kho cov cementitious matrix.
Fly Ash: Ib qho khoom siv los ntawm cov thee combustion, ya tshauv tuaj yeem txhim kho kev ua haujlwm, txo cov cua sov, thiab txhim kho lub zog mus ntev thiab ua haujlwm ntev los ntawm kev ua haujlwm nrog calcium hydroxide los tsim cov cementitious ntxiv.

Metakaolin: Ua los ntawm calcining kaolin av nplaum nyob rau hauv qhov kub thiab txias, metakaolin yog ib tug pozzolan uas txhim khu lub zog mortar, txo permeability, thiab txhim kho durability los ntawm reacting nrog calcium hydroxide los tsim cov cementitious ntxiv.
Polymer Additives: Ntau yam polymers, xws li latex, acrylics, thiab styrene-butadiene roj hmab, tuaj yeem muab ntxiv rau hauv mortar los txhim kho adhesion, yooj, toughness, thiab tsis kam mus rau dej thiab tshuaj.

Cellulose Ether: Cov additives no txhim kho kev ua haujlwm, dej tuav, thiab adhesion ntawm mortar. Lawv kuj txo qis shrinkage thiab tawg thaum txhim kho durability thiab tsis kam mus rau khov-thaw mus.
Superplasticizers: Cov additives no txhim kho qhov ntws ntawm mortar yam tsis muaj dej ntxiv, txhim kho kev ua haujlwm thiab txo qhov xav tau dej ntxiv, uas tuaj yeem cuam tshuam lub zog.
Cua Entrainers: Los ntawm kev sib xyaw cov cua npuas me me rau hauv mortar, cov cua nkag tuaj yeem txhim kho kev ua haujlwm, khov-thaw tsis kam, thiab ua haujlwm ntev los ntawm kev hloov pauv ntim los ntawm qhov kub thiab txias.
Calcium Chloride: Nyob rau hauv me me, calcium chloride accelerates lub hydration ntawm cement, txo lub sij hawm teem thiab txhim kho lub zog thaum ntxov. Txawm li cas los xij, kev siv ntau dhau tuaj yeem ua rau kev txhim kho corrosion.

Sulfate-raws li Additives: Cov tshuaj xws li gypsum los yog calcium sulfate tuaj yeem txhim kho mortar tiv thaiv sulfate nres thiab txo qhov nthuav tawm los ntawm cov tshuaj tiv thaiv ntawm sulfate ions thiab aluminate theem hauv cement.
Corrosion Inhibitors: Cov additives no tiv thaiv embedded steel reinforcement los ntawm corrosion, yog li tswj cov txheej txheem kev ncaj ncees thiab ntev lub neej ntawm mortar ntsiab.
Xim Pigments: Txawm hais tias tsis ncaj qha ntxiv dag zog rau mortar, cov xim xim tuaj yeem muab ntxiv los txhim kho kev zoo nkauj thiab UV tiv thaiv, tshwj xeeb tshaj yog hauv kev siv vaj tse.
Shrinkage Reducing Additives: Cov tshuaj ntxiv no txo ​​qis kev tawg ntawm cov dej los ntawm kev txo cov dej, txhim kho kev sib raug zoo, thiab tswj tus nqi evaporation thaum kho.
Microfibers: Kev sib xyaw cov microfibers, xws li polypropylene lossis iav fibers, txhim kho mortar lub tensile thiab flexural zog, txo kev tawg thiab txhim kho cov kav ntev, tshwj xeeb tshaj yog nyob rau hauv nyias seem.

Cov khoom siv ntxiv ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom khib nyiab, thiab lawv cov kev xaiv thiab kev siv yog qhov tseem ceeb rau kev ua tiav qhov xav tau lub zog, durability, thiab kev ua haujlwm ntawm ntau yam kev siv.
