Lub pob zeb siv sijhawm ntev npaum li cas los kho nrog accelerator?

Yuav koom tes nrog peb li cas?

Thaum cov pob zeb tshiab tso, nws yog ib qho tseem ceeb kom nkag siab txog nws qhov rhiab heev thiab qhov tseem ceeb ntawm kev kho kom zoo. Kev tsis saib xyuas cov txheej txheem tseem ceeb no tuaj yeem ua rau tsis muaj zog, tsis muaj kev ntseeg siab, ua rau raug nqi kho cov kab. Kev kho kom raug tsis yog tsuas yog ntxiv dag zog rau cov pob zeb, tab sis kuj txhim kho nws txoj kev ntseeg siab.

Vim li cas Curing tseem ceeb heev?

Curing tswj qhov kub thiab noo noo nyob rau hauv cov pob zeb, cia nws harden zoo. Cov txheej txheem no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau thawj lub lim tiam tom qab nchuav, vim nws cuam tshuam rau koj txoj haujlwm tiav. Yog tsis muaj kev kho kom zoo, kab rov tav nto, txawm tias cov hniav zoo nkauj lossis cov qauv, yog qhov tsim cov kab nrib pleb zoo, hu ua crazing. Ib lub pob zeb uas tsis tau kho tuaj yeem raug kev txom nyem los ntawm qhov tsis tshua muaj zog thiab qhov chaw abrasive, uas txo nws txoj sia ntev.

Curing Timeframes

Txoj kev kho tag nrho tuaj yeem siv li ib hlis, tab sis pob zeb feem ntau siv tau sai dua. Nov yog cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov:

• 24-48 teev:Tom qab kev teeb tsa thawj zaug, cov ntaub ntawv tuaj yeem raug tshem tawm, thiab lub teeb pom kev zoo yog tso cai.
• 7 Hnub:Nyob rau lub sijhawm no, cov pob zeb tau kho ib nrab thiab tuaj yeem txhawb nqa tsheb thauj mus los.
• 28 Hnub:Tam sim no lub pob zeb yuav tsum tau kho tag nrho, ua tiav lub zog zoo.

Nkag siab Kev Kho: Nws Lub Hom Phiaj thiab Cov txiaj ntsig

Curing ua haujlwm tseem ceeb:

1. Moisture Retention:Nws ua kom cov pob zeb ua kom ntub dej, ua kom lub zog nce ntxiv.
2. Shrinkage Control:Ua kom qhuav shrinkage kom txog thaum lub pob zeb tuaj yeem tiv taus qhov tawg.
3. Lub zog thiab Durability:Txhim khu kev ua tau zoo tag nrho, ua rau nws tiv taus hnav thiab dej nkag.

Kev kho tsis yog tsuas yog hais txog qhov chaw noo noo; nws yog hais txog kev tsim kom muaj ib puag ncig zoo rau kev txhim kho lub zog los ntawm hydration-cov tshuaj tiv thaiv ntawm Portland cement thiab dej. Cov dej noo txaus tso cai rau cov txheej txheem crystalline tsim, uas yog ib qho tseem ceeb rau cov pob zeb kev ncaj ncees.

Temperature's Role in Curing

Qhov kub thiab txias yog lwm qhov tseem ceeb hauv txoj kev kho.

• Huab cua txias:Hauv qab 50 degree F, hydration slows ho; qis dua 40 degree F, nws yuav luag nres. Qhov no tuaj yeem ua rau kev txhim kho lub zog tsis txaus.
• Huab cua kub:Kev kub siab ua kom cov tshuaj tiv thaiv, uas tuaj yeem ua rau tsis sib xws thiab tawg vim muaj hluav taws kub sai.

Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws, nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas ob qho tib si kub thiab noo noo thoob plaws lub sijhawm kho.

Xaus

Peb lub hom phiaj yog los xyuas kom meej tias koj cov pob zeb ncav cuag nws lub peev xwm. Los ntawm kev tswj hwm kev kho kom zoo, peb tuaj yeem tiv thaiv "Cement Monster" los ntawm kev ua kom tsis muaj zog thiab hloov pauv lub hauv paus ruaj khov, kav ntev. Txhawm rau kom tau txais txiaj ntsig zoo, koom nrog cov kws tshaj lij kev cog lus uas tuaj yeem muab cov kws tshaj lij uas xav tau rau kev kho kom zoo.
