Okwangoku, ukusetyenziswa kwei-polycarboxylate superplasticizerii-arhente zokunciphisa amanzi ziqhelekile ekwakhiweni, kuba ukusebenza kwemveliso yabo kunokuphucula amandla okwakha kunye nomgangatho wobunjineli.Le mveliso iluhlaza, ayinakutsha, kwaye ayiqhumi, kwaye inokuthuthwa ngokukhuselekileyo ngololiwe kunye nemoto.Xa i-dosage ye-agent yokunciphisa amanzi ifikelela kwi-0.9% ~ 1.1%, ukuchithwa kwekhonkrithi kunye nomlinganiselo we-samente wamanzi we-0.12-0.16 kunye nesiqulatho sesanti se-38% sinokugcinwa ngaphezu kwe-250mm kwiiyure ze-2, ukwandiswa kunokufikelela kwi-600mm, ixesha lokugqibela lokumisela lingaphakathi kweeyure ze-24, kwaye akukho nto yokwahlula.Amandla oxinzelelo kwiintsuku ze-90 nangaphezulu kwe-180MPa.Ngoko idlala indima ebaluleke kakhulu ekwakheni, kwaye oku kulandelayo kuya kuzisa iingenelo zayo.
1. Umxholo we-alkali kunye nomxholo we-ion we-chloride uphantsi kakhulu, kunye nokongezwa kwei-polycarboxylate superplasticizerutywala oomama akubangeli umonakalo wokugqwala kwiintsimbi zentsimbi kwaye akukho miphumo emibi kwikhonkrithi.Kwangaxeshanye, imveliso ayinayo ityuwa okanye icwebe ngexesha lobushushu obuphantsi, nto leyo eyenza kube lula ukuyisebenzisa.
2. Kuyinzuzo ekusebenzeni kwemixube ekhonkrithi, kunciphisa ukuphuma kwegazi, kuphucula umgangatho wokubonakala kunye nokuqina kwekhonkrithi eqinile, kwaye ifaneleke ngokukodwa ukusetyenziswa kwiiprojekthi zekhonkrithi ezicacileyo.
3. Ikhonkrithi elungiswe ngei-polycarboxylate superplasticizeramanzi okunciphisa arhente umama utywala akayi kubonakalisa ukwahlulwa okucacileyo okanye ukopha naphantsi kweemeko eziphakamileyo zokudilika, kunye nenkangeleko yombala wekhonkrithi iyunifomu.Xa isetyenziselwa ukulungisa i-concrete yezinga eliphezulu, ikhonkrithi inokusebenza kakuhle, ukudibanisa okulungileyo, kwaye kulula ukuyixuba.
Ke iiarhente zokunciphisa amanzi epolycarboxylate ziyimfuneko kakhulu ekwakhiweni.Xa zisetyenziswa, zidla ngokudityaniswa ngokomlinganiselo, nto leyo enganeli nje ukwenza iprojekthi yomelele ngakumbi kodwa ikwanciphisa neengozi ezahlukahlukeneyo.Kuphela ngokuqonda iimpawu eziphathekayo kunye neenzuzo sinokuzisebenzisa kakuhle kwixesha elizayo.Polycarboxylate superplasticizeri-arhente yokunciphisa amanzi yi-arhente yokunciphisa amanzi ephezulu kunye ne-samente dispersant esetyenziselwa ukusetyenziswa kwekhonkrithi yesamente.Isetyenziswa kwiiprojekthi ezifana nohola wendlela, iibhulorho, amadama, itonela, kunye nezakhiwo eziphakamileyo.
