Txawm hais tias cov khau khiab tau nce ntxiv, tseem muaj ntau cov tshuaj seem thiab txawm tias tsis yog, uas cuam tshuam rau cov kev sib tw ntawm cov pob zeb. Ntxiv cov dej me me khaws tus neeg sawv cev tau ua rau muaj teeb meem ntau rau kev tsim kho. Cov xuab zeb piv ntawm cov pob zeb muaj cuam tshuam rau daim ntawv thov cov nyhuv ntawm poly carboxylate superplasticer. Thaum siv cov dej uas muaj peev xwm txo cov dej num hauv dej siab, cov xuab zeb sib piv tuaj yeem tsim nyog nce thiab cov ua kom zoo dua qub tuaj yeem txhim kho.

Thaum sib xyaw nrogPolycarboxylate Superplasticizer, cov xuab zeb piv yog cov siab thiab lub fluidity ntawm cov pob zeb ua tsis zoo. Cov khoom lag luam ntawmPolycarboxylate SuperplasticizerHom dej txo tus neeg sawv cev nrog huab cua nkag muaj cov carboxyl adsorption noob thiab muaj ntau cov ceg. Polyether Sideins muab sticer thaiv, thaum cov polyethers muaj ntau lub zog.

Vim muaj qhov sib txawv hauv cov txheej txheem ntau lawm thiab cov roj molecular qhov sib txawv ntawm cov ntaub ntawv raw siv los ntawm cov khoom lag luam sib txawv, tseem muaj qhov sib txawv ntawm huab cua enrainment. Ntawm ob peb poly carboxylate superplasticizer cov khoom peb tau sim, cov ntshav qis dua 3%, thiab muaj 6%, thiab qee cov khoom lag luam txawm txog 8%.

Yog li ntawd, thaum siv cov dej num dej siab ua kom txo cov neeg sawv cev, nws yog qhov tsim nyog los ua ntej siv ua ntej siv ua ntej siv tau ntawm qhov project.
