Thaum ntxiv Polycarboxylate superplasticizer, qhov xwm txheej ntawm vau yog qhov tsawg, uas tseem tsis hloov ntawm qhov kub tsis tshua zoo, thiab qhov ntsuas ntawm kev nthuav dav tau nce ntxiv. Yog tias qhov ntsuas kub siab tshaj 20 degree, qhov poob qis me ntsis ploj. Nrog rau qhov ua kom tsis zoo ntawm qhov qis hauv qhov siab, yuav tsis muaj qhov sib cais lossis los ntshav, tus neeg sawv cev txo cov dej yog feem ntau haum rau cov pob zeb siab, thiab yooj yim sib xyaw.
Lub sijhawm ua haujlwm ntawm polycarboxylate superplasticizer zoo dua, thiab nws sau thiab kev ruaj khov zoo dua li ntawm cov superplasticizer zoo tib yam. Thaum nws tau muab sib xyaw nrog cov sib txawv ntawm cov xis mas, kev sib raug zoo ntawm lwm cov khoom plig thiab cov cementitious tuaj yeem daws teeb meem.
Tom qab siv cov polycarboxylic acid superplasticizer, cov khoom muaj cov kev ruaj ntseg zoo dua, thiab yuav tsis muaj nag lossis daus thaum tsis kub. Nws yog cov khoom lag luam ntsuab heev, uas tuaj yeem txo cov pa phem rau ib puag ncig. Yog qhov khoom haum los ntawm feem ntau ntawm cov neeg siv khoom.
