Cement pob zeb pavement yog ib qho kev pavement tam sim no. Tsuas yog los ntawm kev ua kom ntseeg tau lub zog, flatness thiab hnav tsis kam, tuaj yeem ua haujlwm zoo. Daim ntawv no ua rau muaj kev ntsuam xyuas dav dav ntawm kev tsim kho cov cement pob zeb hauv kev txhawm rau txhim kho nws cov kev ua tau zoo thiab ua tau raws li cov kev xav tau ntawm cov tsheb zoo.

Pavement engineering yog qhov tseem ceeb tshaj plaws ntawm txoj kev tsim kho engineering. Nws tsis tsuas yog siv ntau cov ntaub ntawv, tab sis kuj muaj cov txheej txheem nyuaj. Yog tias nws tsis raug kho kom raug, teeb meem yuav tshwm sim, cuam tshuam rau kev nyab xeeb ntawm tsheb. Qhov cuam tshuam ncaj qha tshaj plaws ntawm kev kho pavement tsis raug yog tias cov txheej txheem rhiab yuav raug tsim los ntawm kev hloov pauv ntawm qhov chaw sab nraud, uas ua rau muaj ntau yam teeb meem ntawm pavement zoo. Cov cheeb tsam sib txawv yuav tsum tau xaiv cov ntaub ntawv pavement raws li lawv tus kheej ib puag ncig, thiab txhim kho kev txawj ntse ntawm pavement raw khoom xaiv, grading composition design, test detection level, build process control, process level, equipment technology level, building environment, etc. ., yog li mus nteg lub hauv paus rau kev tsim kho ntawm high-quality highways. Tam sim no, feem ntau cov pavement yog cement pob zeb pavement, uas muaj kev ruaj ntseg siab vim nws compression, dabtsi yog khoov thiab abrasion tsis kam. Nyob rau tib lub sijhawm, txoj kev taug kev zoo li no kuj muaj ntau yam zoo, xws li kev ua haujlwm ntev, cov nqi tu txhua hnub tsawg dua, thiab muaj txiaj ntsig zoo rau kev tsav tsheb thaum hmo ntuj. Txhawm rau kom ntseeg tau tias cov cement pob zeb ua haujlwm tuaj yeem ua nws lub luag haujlwm, nws yuav tsum tau ua tib zoo tsim thiab nruj kev tsim kho, thiaj li ua kom zoo thiab muab kev ua si rau qhov zoo ntawm cement pavement.

Kev xaiv cov dej ntxiv:

Kev tsim kho cement xav tau cov khoom siv ntxiv, uas tuaj yeem txhim kho lub zog thiab hardness ntawm cov cement. Cov khoom siv feem ntau suav nrog cov dej txo tus neeg sawv cev, tus neeg sawv cev fluidizing thiab lwm yam ntaub ntawv. Los ntawm kev sib xyaw nrog cov cement, qhov ua tau zoo ntawm cov pob zeb tuaj yeem ua kom zoo dua qub. Cov dej huv uas tsis muaj impurities yuav tsum raug xaiv los siv. Dej nrog impurities tsis tuaj yeem siv, uas yuav cuam tshuam rau hardening ntawm cement.

Influence ntawm additive npaum li cas ntawm qhob slump:

Additive yog ib yam khoom tseem ceeb. Nws cov nyiaj muaj txiaj ntsig zoo rau cov pob zeb tawg thiab yog ib qho tseem ceeb. Additive yog ib qho catalyst los txhawb lub cev thiab tshuaj lom neeg ntawm pob zeb. Ntau dhau los yog tsawg dhau yuav tsis tsim cov txiaj ntsig zoo.
