Esokuqala siwudaka esihlabathini.Lapho okuqukethwe kodaka esihlabathini kuphezulu, izinga lokunciphisa intela lei-ejenti yokunciphisa amanzi ye-polycarboxylic acidkuncishiswe kakhulu, futhi ushintsho alubonakali lapho okuqukethwe kunyuswa.Isixazululo: Sebenzisa leli qoqo lesihlabathi ukhonkolo ojwayelekile wezinga eliphansi;lawula ngokuqinile okuqukethwe kodaka esihlabathini futhi udinga ukuthi okuqukethwe kodaka okungenani kube ngaphansi kuka-2%.
Okwesibili yinkinga engancibilikiyo yesihlabathi kanyeamanzi e-polycarboxylic acid i-ejenti yokunciphisa.Uma ukuhlukaniswa, okuqukethwe kodaka, nodaka lwesihlabathi kuhlangabezana nezidingo, akuncibiliki nge-ejenti yokunciphisa amanzi ye-polycarboxylic acid.Ukwakheka kwamakhemikhali kushayisana nokwakheka kwe-i-ejenti yokunciphisa amanzi ye-polycarboxylic acid, futhi ukhonkolo oxubile awunawo uketshezi.Isixazululo: Eqeqebeni ngalinye lesihlabathi esingena endaweni, uma izinkomba ezibonakalayo zifanelekile, phinda uhlole isilinganiso sokuxuba ukwakhiwa kokhonkolo ukuze ukhiphe isihlabathi esingancibiliki esizeni.
Khona-ke ukulahlekelwa kwe-concrete slump kuyashesha, okudingayoumenzi we-ejenti yokunciphisa amanziukwengeza i-ejenti yokugcina i-slump, bese usebenzisa izinto zokusetshenziswa ezikusayithi ukwenza ukuhlolwa kabusha kwe-mix ratio ukulungisa ukulahleka kokuwohloka ukuze kuhlangatshezwane nezidingo zokwakha.
