I-Retarder ingukuhlanganiswa okuvimbela i-hydration ka usimende nokwandisa isikhathi sokushintsha kwengxube kusuka epulasitiki kuya e-Hard State. Ngakho-ke, ingasetshenziswa ngokhonkolo kwezohwebo ukuthuthukisa ukugcinwa kokhonkolo kakhonkolo. Kubaluleke kakhulu kukhonkolo yezentengiso. izithako zokuhlanganiswa.
Eqinisweni, indima yabadayisi ingaphezulu kakhulu kunokuthuthukisa ubukhulu bekhonkolo yezohwebo.
. Ukuhlolwa kukhombisile ukuthi umphumela wokunciphisa amanzi we-sodium glucinate evame ukusetshenziswa kwe-sodium izikhathi eziningana enaye ama-superplastizer asetshenziswa kakhulu asetshenziswa ama-naphthalene. wamukelwa. Ngesikhathi sokwakhiwa kwamazinga okushisa aphezulu, kwandise umthamo we-sodium gluconate, izindleko zokwakha ngeke zikhuphuke, ngoba umthamo we-ejenti yokunciphisa amanzi ehambisanayo angancishiswa kakhulu.

Ukusetshenziswa ngokweqile kwesibuyisi ekwakhiweni kokhonkolo kwezohwebo akusizi ngalutho. Ukusetshenziswa ngokweqile kwe-retarder kukhonkolo ngeke kuthinte kuphela ukuthuthukiswa kokhonkolo kusenesikhathi ngokhonkolo, kodwa futhi kuthinta inqubekela phambili yokwakha. Ngenxa yesimo sepulasitiki sesikhathi eside, izovezwa umoya kanye nelanga emkhathini, futhi amanzi asendaweni ekhonkolo azothinteka. Inani elikhulu lokuhwamuka likhulisa ukulahleka kwamanzi ebusweni kokhonkolo, okuphumela ekuqhekekeni okuncane. Njengoba ukulahleka kwamanzi kukhuphuka, imifantu ikhula ekujuleni, izinga le-liquid lamanzi ku-pores ukhonkolo, ukucindezela okungatheni kwanda kancane, futhi okuholela ekunciphiseni amandla okuncipha ngenxa yokuncipha kwamanzi.
Ukhonkolo osesimweni sepulasitiki isikhathi eside uzobangela ukukhishwa kwegazi nokuguquguquka okungalingani phakathi kwama-aggregate kanye nezinto zokwakha dementile. Ngokusho kovivinyo, ukushwabana kwepulasitiki ngokhonkolo esimweni sepulasitiki isikhathi eside kungafinyelela ku-1%, okunomthelela omuhle kwikhwalithi kakhonkolo.
