Maitiro ekugadzira maitiro:
(1) Paunenge uchigadzira chikamu chekongiri musanganiswa, kushandiswa kwemusanganiswa kwepamusoro-inoshanda-inoderedza mvura mumiriri uye mhepo-inopinza mumiriri inogadzirisa zvinodikanwa zvekugara kwekongiri zvimiro munzvimbo dzinotonhora zvakanyanya;
(2) Nekubatanidza slump-preserving components mu-high-performance-reduction-deduction admixtures, kukanganisa kwekushisa kwepamusoro muzhizha pakushanda kwekongiri kunogadziriswa;
(3) Kuburikidza nekuongorora kwekuyedza, pesvedzero yedhaka yemukati mukongiri pakushanda uye kumanikidza simba rekongiri;
(4) Nekugadzira jecha rakaomarara uye jecha rakanaka mune imwe chikamu, chiitiko chekuti rudzi rumwe rwejecha rekongiri harugone kusangana nekushanda kwekongiri inogadziriswa;
(5) Zvinhu zvinokanganisa kushanda kwekrete zvinotsanangurwa, uye kukanganisa kwezvinhu zvakashata pakushanda kwekushanda kwekrete kunodziviswa panguva yekugadzira konkrete.
Iyo yekushanda musimboti wepamusoro-inoshanda yekudzikisa mvura mumiririri:
(1) Dispersion: Iyo inoderedza mvura inonamira yadsorbed pamusoro pezvimedu zvesimende, zvichiita kuti vatakure charger imwechete kuti iite electrostatic repulsion, iyo inosimudzira masement particles kuti apararire pamwe chete, inoparadza iyo flocculation chimiro chakaumbwa ne simende slurry, uye inosunungura chikamu chemvura yakaputirwa.Zvinobudirira kuwedzera fluidity kongiri musanganiswa.
(2) Lubricant effect: Mvura inoderedza mvura ine boka rakasimba re hydrophilic, iyo inoumba firimu remvura pamusoro pezvikamu zvesimenti, kuderedza kusvetera kupikisa pakati pezvikamu zvesamende, nokudaro kuwedzera kuwedzera kwemvura yekrete.
(3) Steric chipingamupinyi: Mvura inoderedza mvura ine hydrophilic polyether side maketani, iyo inoumba hydrophilic matatu-dimensional adsorption layer pamusoro pemasimende esimende, zvichiita kuti steric chipingamupinyi pakati pemasimende, nokudaro kuve nechokwadi kuti kongiri ine zvinhu zvakanaka.slump.
(4) Kunonoka-kuburitsa mhedzisiro yematavi akaiswa copolymerized: Panguva yekugadzira uye kugadzirira maitiro matsva ekudzikisa mvura, maketani ane matavi ane chaiwo mabasa anowedzerwa.Iyi ketani yebazi haina kungoita steric hindrance athari, asi zvakare inogona kushandiswa panguva yekukwira kwe hydration ye simenti.Polycarboxylic acids ine dispersing mhedzisiro inoburitswa munzvimbo ine alkaline, iyo inovandudza kupararira kwesement masisitimu uye zvinobudirira kudzora kudonha kwekongiri mukati meimwe nguva yenguva.
