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. Lapho 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 kusayithi, uma izinkomba ezibonakalayo zifanelekile, phinda uhlole isilinganiso sengxube yokwakha ukhonkolo ukuze ususe 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 ukuze ulungise ukulahleka kokuwohloka ukuze kuhlangatshezwane nezidingo zokwakha.
