Pob zeb yog tam sim no siv cov khoom siv hauv tsev ntau tshaj plaws, thiab kuv lub teb chaws yog cov neeg siv khoom loj tshaj plaws hauv lub ntiaj teb.Raws li ib hom kev sib xyaw ua ke, cov dej reducer tsuas muaj keeb kwm ntawm ntau xyoo lawm, tab sis nws txoj kev loj hlob sai heev, thiab nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog siab thiab kev ua haujlwm siab ua vaj tse.

Txij li thaum lub advent ntawm polycarboxylate superplasticizer nyob rau hauv lub xyoo 1980s, vim nws zoo heev zoo xws li tsis tshua muaj npaum li cas, zoo slump tuav, thiab tsis tshua muaj pob zeb shrinkage, nws tau nyiam ntau thiab ntau xim los ntawm kev lag luam, thiab tam sim no tau los ua ib tug npaj txhij-sib xyaw.Lub ntsiab hom dej txo tus neeg sawv cev yog dav siv nyob rau hauv high-speed railways, txoj kev loj, txuas hniav, tunnels, subways, high-sawv vaj tse thiab lwm lub teb chaws tej yaam num tseem ceeb, daws ib tug series ntawm technical teeb meem.

Txawm hais tias pob zeb dej reducer muaj kev lag luam dav heev, cov qauv ntawm cov tsev niaj hnub no thiab kev tsim kho hnyav ntawm qhov kub thiab txias tau muab tso rau ntau thiab ntau dua cov kev xav tau rau kev ua tau zoo ntawm cov khoom siv pob zeb, thiab kev ua haujlwm siab ntawm cov pob zeb ua dej reducer raws li ib qho tshiab. Cov khoom siv tshuaj lom neeg kuj ntsib teeb meem ib puag ncig loj.Cov xwm txheej tam sim no tau ua rau cov kev tshawb fawb thiab kev tsim khoom ntawm cov pob zeb ua dej txo qis kom txuas ntxiv ua cov kev tsim kho tshiab ntawm cov pob zeb ua dej reducers.

Nrog rau kev txhawb nqa loj tam sim no ntawm kev lag luam vaj tsev, kev tsheb ciav hlau thiab lwm yam kev tsim kho hauv nroog thiab lub sijhawm thoob ntiaj teb ntawm lub teb chaws "Belt and Road", tus neeg saib xyuas dej txo qis yuav pab kev lag luam pob zeb thiab ua rau nws lub caij nplooj ntoos hlav.Rau lub sijhawm ntev nyob rau yav tom ntej, polycarboxylate superplasticizers yuav tuav txoj haujlwm tseem ceeb hauv cov pob zeb sib xyaw ua ke hauv cov qauv tshwj xeeb xws li cov tsev siab siab thiab ultra-loj spans thiab nyob rau hauv ib puag ncig hnyav xws li kub.
