Cov nyhuv ntawm Compatibility ntawm Admixture Thiab Cement Ntawm Qhob

Yog hais tias ntxiv cov dej txo tus neeg sawv cev tuaj yeem ua kom cov dej ntws ntawm cov pob zeb ua kom zoo tib yam dej haus, lossis txo cov dej hauv chav ua kom zoo li qub, yog li kev txhim kho lub zog ntawm cov pob zeb, txhim kho cov durability ntawm cov pob zeb, thiab lwm yam. Yog li, tuaj yeem nkag siab pob zeb. admixture thiab lub tswv yim ntawm adaptability ntawm cement thiab inadaptability: raws li cov kev qhia tshwj xeeb rau cov pob zeb admixture daim ntaub ntawv thiab yuav ua raws li cov qauv tsim tom qab kev tshuaj xyuas ntawm qee yam admixture ntxiv rau kev siv raws li cov kev cai, tuaj yeem siv ntau hom admixture. cement sib tov ntawm pob zeb, yog tias tuaj yeem tsim cov txiaj ntsig, yog hloov mus rau cov cement thiab cov khoom sib xyaw; Ntawm qhov tsis sib xws, yog tias cov nyhuv tsis tuaj yeem tsim tau, muaj qhov tsis zoo ntawm cov cement thiab cov khoom sib xyaw. Xws li: nrog rau ntau yam Portland cement thiab sib xyaw nrog qee yam kev ua haujlwm siab dej txo tus neeg sawv cev (kev sim ua raws li cov qauv zoo rau kev ua haujlwm siab dej txo tus neeg sawv cev) tsim cov pob zeb, nyob rau hauv cov xwm txheej ntawm kev npaj cov xwm txheej zoo ib yam, muaj yog ib qho cement pob zeb npaj los ntawm qhov tsis txaus ntawm cov dej txo qis, qhia tau hais tias cov cement no thiab cov neeg ua haujlwm siab dej txo tus neeg saib xyuas tsis hloov, thiab ob peb lwm cov cement thiab cov neeg ua haujlwm siab dej txo tus neeg sawv cev. Ib zaug ntxiv yuav zoo li, thaum cov pob zeb uas qee yam ntawm cov cement qhov chaw ua kom sib xyaw ntxiv cov neeg ua haujlwm nrawm uas ua raws li cov txheej txheem tsim nyog los ntawm kev ntsuam xyuas kom tau txais cov nyhuv coagulate ceev txawm li cas los xij, lossis ntxiv tus neeg saib xyuas ncua coagulate kom tau txais cov nyhuv coagulate cuav txawm li cas los xij, tuaj yeem ua tau. xav tias yog tshwm sim los ntawm kev tsis sib haum xeeb ntawm kev sib xyaw thiab cement. Yuav luag txhua yam ntawm cov cement thiab admixture ntawm adaptability teeb meem, yog tam sim no feem ntau siv, dej txo tus neeg sawv cev thiab thaum nws thiab cement tsim inadaptability rau intuitive teb sai sai, xws li tsis zoo liquidity, tsawg dej txo tus nqi, los yog harden sib tov tshwm sim xws li. raws li kub taub hau, fluidity poob sai heev).
