Kev siv cov tshuaj sib tov los txhim kho cov txiaj ntsig zoo:

Cov pob zeb sib xyaw nrog cov khoom siv ntxiv, xws li kev ua haujlwm siab dej txo tus neeg saib xyuas thiab tus neeg saib xyuas lub zog thaum ntxov, tuaj yeem ua pob zeb 7 ​​hnub ntawm lub zog ntau dua 1 zaug, txo cov ntshav los ntshav, txhim kho cov dej txo qis, thiab hauv cov qauv 28 hnub tom qab lub zog sib piv. tuaj yeem ncav cuag ntau dua 150%, yog li hauv kev npaj lub zog siab lossis ultra siab zog pob zeb ua tau yooj yim ua tiav. Nyob rau hauv lub zog ntawm cov pob zeb sib xyaw nrog admixture txhim kho tib lub sijhawm, txhim kho nws cov haujlwm ua haujlwm thiab cov dej tso tawm, thiab kho cov ntsiab lus ntawm huab cua, txhim kho corrosion kuj, alkali aggregate cov tshuaj tiv thaiv, txhim kho cov hlau xeb, txhim kho lub zog cohesive, qhov no tsis yog xwb. Txhim kho qhov siv ntau yam ntawm cov pob zeb, thiab txuag cov khoom siv, txuag cov cement lossis hloov cov cement tshwj xeeb. Thiab nyob rau hauv cov pob zeb sib xyaw nrog qeeb hom dej txo tus neeg sawv cev, tuaj yeem kho lub sijhawm teeb tsa, txhim kho lub twj tso kua mis, ncua lub sijhawm ua vaj tse thiab lub sijhawm hardening, tuaj yeem ua tau raws li qhov sib txawv engineering, tshwj xeeb tshaj yog cov pob zeb ua vaj tse loj thiab kev xav tau zoo. Thaum xaiv cov khoom sib xyaw hauv cov pob zeb, nws yog ib qho tsim nyog yuav tsum xav txog cov yam ntxwv ntawm cov cement ntau yam thiab lwm yam khoom siv tib lub sijhawm, thiab xaiv ntau hom dej txo tus neeg sawv cev raws li lub hom phiaj sib txawv. Thaum xaiv cov dej txo tus neeg sawv cev, nws yog ib qho tsim nyog yuav tsum xav txog kev lag luam thiab ua tib zoo saib xyuas qhov zoo ntawm cov dej txo tus neeg sawv cev. Yog tias ua tau raws li qhov teeb meem uas cov cement thiab cov khoom siv tsis tau siv rau, yuav tsum tshem tawm cov kev txhawj xeeb los ntawm kev sim, xaiv cov dej uas tsim nyog txo tus neeg sawv cev, tsom xam cov cement txhawj xeeb txog qhov teeb meem zoo, txiav txim siab qhov tsim nyog cov khoom sib xyaw, kev sib xyaw ua ke sib piv. Nyob rau hauv kev siv ntawm ob peb admixtures, nws yuav tsum tau them sai sai mus rau lub compatibility ntawm ntau yam thiab cov kev cuam tshuam ntawm kev ua vaj tse, yuav tsum tau kuaj ua ntej siv, xws li polycarboxylic acid system high-performance water reducer thiab naphthalene system dej reducer yuav tsum tsis txhob yuav. kev siv sib xyaw. Nrog rau kev txhim kho thiab kev siv cov khoom sib xyaw ua ke, nws tau kov yeej qhov tsis muaj zog ntawm qhov tsis muaj zog, siab brittleness thiab lwm yam, thiab ua kom muaj kev txhim kho txuas ntxiv, txo lub sijhawm luv luv, txhawb kev txhim kho ntawm cov twj tso kua mis thiab cov cuab yeej tshiab ntawm kev siv thiab pouring, thiab accelerated txoj kev loj hlob ntawm kev lag luam pob zeb. Txoj kev loj hlob ntawm kev lag luam pob zeb tau coj cov txiaj ntsig zoo ntawm kev lag luam thiab kev tiv thaiv ib puag ncig rau Tuam Tshoj kev tsim kho kev lag luam, thiab ntxiv dag zog rau kev tsim kho kev lag luam thiab kev txhim kho kev tsim kho tshuab.
