Polycarboxylic acidIi-arhente zokunciphisa amanzi zinokuhlangabezana neengxaki ezininzi kwizicelo ezibonakalayo. Ngoku makhe sithethe iingxaki eziqhelekileyo ekudityanwe nazo kwizicelo zobunjineli kunye nezisombululo zazo.
Eyokuqala sisiqulatho sodaka esantini. Xa isiqulatho sodaka esantini siphezulu, izinga lokunciphisa irhafu yei-agent yokunciphisa amanzi ye-polycarboxylic acidiyancipha kakhulu, kwaye utshintsho alubonakali xa umxholo wonyuswa. Isisombululo: Sebenzisa le bhetshi yesanti kwi-concrete yomgangatho ophantsi; lawula ngokungqongqo umxholo wodaka lwesanti kwaye ufuna umxholo wodaka ube ngaphantsi kwe-2%.
Okwesibini yingxaki enganyibilikiyo yesanti kunyepolycarboxylic acid amanzi i-arhente yokunciphisa. Xa i-gradation, umxholo wodaka, kunye nomxholo wodaka wesanti uhlangabezana neemfuno, awunyibiliki nge-polycarboxylic acid yokunciphisa amanzi. Ukwakhiwa kweekhemikhali kuyangqubana nokubunjwa kwei-agent yokunciphisa amanzi ye-polycarboxylic acid, kwaye ikhonkrithi edibeneyo ayinayo i-fluidity. Isisombululo: Kwibhetshi nganye yesanti engena kwisiza, ukuba izikhombisi ezibonakalayo zifanelekile, phinda uphinde udibanise umxube wokwakhiwa kwekhonkrithi ukususa isanti engenakunyibilika kwisiza.
Emva koko ilahleko yekhonkrithi yekhonkrithi ikhawuleza, efunaumenzi wearhente yokunciphisa amanziukongeza i-ejenti yokugcinwa kwe-slump, kwaye emva koko usebenzise izixhobo eziluhlaza kwisayithi ukwenza uhlaziyo lomxube wokuxuba ukulungelelanisa ilahleko ye-slump ukuhlangabezana neemfuno zokwakha.
Eyokugqibela yimeko yokopha kwekhonkrithi. Ngaphantsi kweemeko zemvula, i-concrete ye-C50 yagalelwa kwaye ikhonkrithi yakhutshwa kwi-tanker ikwimeko efanelekileyo, kodwa emva kokuba ikhonkrithi ishukunyiswa, kwakukho ukopha kunye nokwahlula. Isisombululo: Nciphisa ukusetyenziswa kwamanzi, ukwandisa ixesha lokuxuba, ukunciphisa umxholo we-0.1%, i-concrete vibrating ayigazi, kwaye wenze imizekelo yekhonkrithi ngeentsuku ezingama-28 zamandla okunyamezela ukufikelela kumandla oyilo.
