Qhov cuam tshuam tom qab siv admixture polycarboxylate superplasticizer

Los ntawm kev thov rau admixture polycarboxylate superplasticizer hauv cov pob zeb ua pob zeb, thawj zaug, nws tuaj yeem txhim kho lub peev txheej tiv thaiv kev tiv thaiv hauv av. Vim hais tias ntawm ib puag ncig kev ua qias tuaj, muaj ntau yam phom sij hauv av, uas muaj qee yam ntxim nyiam hauv cov pob zeb. Yog li no, txhim kho qhov muaj peev xwm tiv thaiv corrosion ntawm pob zeb tuaj yeem txhim kho kev ua vaj tse ruaj khov. Thib ob, txhim kho lub peev xwm dej permeability, lub hauv paus pob zeb loj yog qhov yooj yim engineering ntawm lub tsev, lub permeability ntawm cov dej hauv av tsis tso cai tsis quav ntsej: qhov thib peb, txhim kho lub peev xwm chloride ion permeability, chloride ion muaj qhov cuam tshuam loj heev rau ntawm qhov cuab lub zog. , lub sijhawm ntev yuav cuam tshuam rau kev ruaj khov ntawm tag nrho cov qauv.
