Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
I-superplasticizer yinto engezwa emkhiqizweni noma impahla ukuze kwandiswe ipulasitiki yayo. Inganciphisa okuqukethwe kwamanzi futhi yenze umkhiqizo ube thambile. Kungandisa futhi ukuqina namandla omkhiqizo.
Ama-Superplasticizers asetshenziswa njengenhlanganisela yokuthuthukisa ikhwalithi nokuqina kukakhonkolo. Bangasiza ekwenzeni ngcono ukugeleza kukakhonkolo, ukuvimbela ukuhlukaniswa kwezinhlayiya ekumisweni, kanye nokubambezeleka kokumiswa kukasimende. Bangasiza futhi ekwehliseni ukungena kokukhonkolo.
Amanye ama-superplasticizer ayenziwe kanti amanye angokwemvelo. Ngokuvamile zisekelwe ku-lignosulphonate. Ama-molecule e-superplasticizer makhulu ngokuphindwe kayikhulu kune-molecule yamanzi.
Ngokuvamile zisetshenziselwa ukunciphisa inani lamanzi adingekayo kungxube kakhonkolo. Bangakwazi ukunciphisa isilinganiso samanzi kuya kusimende, okungase kwandise amandla nokuqina kokhonkolo. Bangaphinde banciphise ukushwabana kukakhonkolo futhi bangandisa inqubo ye-hydration. Bangasiza futhi ekulawuleni izinga lokushisa likakhonkolo ngamavolumu amakhulu.
Zibuye zisetshenziswe kaningi njenge-axiliary kuma-plaster, izimonyo, kanye nama-ejenti okuhlanza. Zivame ukungezwa kusimende cishe 0.5-0.3% yesisindo sikasimende. Zibuye zisetshenziswe njengensiza ekukhiqizeni imikhiqizo yepulasitiki.
Umthamo we-plasticizer unqunywa ukuhlolwa kwe-Marsh Cone. Ingahluka kusuka kumalitha amahlanu kuya kwamashumi amabili we-plasticizer per cubic meter kakhonkolo. Kuvame ukuxutshwa ngesikhathi sokuxuba futhi ngesikhathi sokuthululela isayithi.
