cov nyhuv ntawm superplasticizer rau cov pob zeb tshiab
Cov nyhuv ntawm superplasticizer ntawm cov khoom ntawm cov pob zeb tshiab yog nyob ntawm ntau hom thiab ntau npaum li cas. Ib qho superplasticizer yog siv los ua kom zoo dua cov dej-cement piv, workability thiab lub zog ntawm pob zeb. Nws tseem tuaj yeem txhim kho qhov ntws ntawm cov pob zeb thiab txhim kho tus kheej-leveling cov yam ntxwv los ntawm kev txo cov ntsiab lus dej.
Nyob rau hauv thawj theem ntawm hydration, lub superplasticizer txhawb kev muaj zog hydration cov tshuaj tiv thaiv los ntawm kev sib txuas ntawm cov cement particles uas ua rau ntau dua fluidity thiab permeability.. Nws kuj txo qis w / b ration ntawm cov cement uas ua rau muaj zog thaum ntxov thiab txhim kho durability.
Nws tuaj yeem siv los ua cov khoom siv tseem ceeb hauv kev sib xyaw ntawm tus kheej-compacting pob zeb rau kev txhim kho durability, los yog raws li ib tug thib ob admixture nrog rau lwm yam dej-txo additives nyob rau hauv siab zog thiab hardened pob zeb kom txo tau cov kev siv ntawm cov dej-retaining curing agents.
Cov tshuaj no tuaj yeem sib xyaw nrog cov khoom xyaw qhuav, los yog ntxiv rau hauv dej 10-15 feeb ua ntej casting. Nws tuaj yeem muab ntxiv rau hauv pob zeb thaum sib xyaw hauv cov cuab yeej siv tshuab lossis tshuaj khib tov (sib tov lub sij hawm yog 3 feeb).
Qhov txiaj ntsig tseem ceeb tshaj plaws ntawm kev siv superplasticizer yog tias nws tsis nce cov huab cua hauv kev sib xyaw. Cov cua no tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb, tab sis nws kuj txo cov kav ntev yog tias qhov sib tov tsis kho tag nrho ua ntej thov.
Nws raug nquahu kom siv superplasticizer thaum lub pob zeb ua haujlwm ntawm nws qhov siab tshaj plaws ntawm kev ua haujlwm thiab ua ntej nws mus txog qhov poob qis uas feem ntau yuav tshwm sim.. Nws kuj tseem pom zoo kom tsis txhob ntxiv cov khoom siv cua-entrained nrog cov khoom sib xyaw no vim tias nws yog qhov ua rau microbial nres..
