Apr 28, 2020
Superplasticizers yog cov tseem ceeb ntawm cov pob zeb ua niaj hnub, tso cai rau kev tsim cov txheej txheem ruaj khov nrog txo kev cuam tshuam ib puag ncig. Lawv cov haujlwm ua haujlwm ua raws lawv cov txheej txheem molecular thiab lub cev – tshuaj sib cuam tshuam ntawm lawv thiab cov nplaim ntawm cov nplaim hluavtaws.Yog qee lub sijhawm, nws nyuaj lossis nrhiav tsis tau qhov sib xyaw ua ke muab qhov xav kom ua haujlwm thiab ua haujlwm kom paub yam tsis muaj lub siab ntev. Cov xwm txheej zoo li no tau piav qhia ua cov cement – superplasticizer incompatibilities. Ib qho kev sim ua kom zoo dua qub keeb kwm ntawm cov kev tsis sib xws tau nthuav tawm hauv tshooj no, hais txog lub luag haujlwm ntawm soluble alkali, C 3 A, thiab ib qho chaw tshwj xeeb. Cov kev paub ntawm cov neeg kho tshuab nrog rau cov kev qhia pom zoo yuav tsum tau pab ua kom zoo dua tswj kev ua tau zoo ntawm admixed pob zeb ua ke.
