Iiarhente zokunciphisa amanzi epolycarboxylic acid zinokudibana neengxaki ezininzi kwizicelo ezisebenzayo. Ngoku makhe sithethe iingxaki eziqhelekileyo ekudityanwe nazo kwizicelo zobunjineli kunye nezisombululo zazo.

Eyokuqala sisiqulatho sodaka esantini. Xa udaka lwesanti luphezulu, izinga lokunciphisa irhafu ye-polycarboxylic acid ye-agent yokunciphisa amanzi iyancipha kakhulu, kwaye utshintsho alubonakali xa umxholo wanda. Isisombululo: Sebenzisa le bhetshi yesanti kwi-concrete yomgangatho ophantsi; lawula ngokungqongqo umxholo wodaka lwesanti kwaye ufuna umxholo wodaka ube ngaphantsi kwe-2%.

Okwesibini kukungahambelani phakathi kwesanti kunye ne-agent ye-polycarboxylic acid yokunciphisa amanzi. Xa i-gradation, umxholo wodaka, kunye nodaka lwesanti luhlangabezana neemfuno, alunyibiliki kunye ne-polycarboxylic acid yokunciphisa amanzi, kunye nesanti inezinye Ukwakheka kweekhemikhali kungqubana nokubunjwa kwe-polycarboxylic acid yokunciphisa amanzi, kwaye ikhonkrithi exutyiweyo ayinamanzi. Isisombululo: Kwibhetshi nganye yesanti engena kwisiza, ukuba izikhombisi ezibonakalayo zifanelekile, phinda uphinde udibanise umxube wokwakhiwa kwekhonkrithi ukususa isanti engenakunyibilika kwisiza. Emva koko ilahleko yokuthotywa kwekhonkrithi ikhawuleza, nto leyo ifuna umenzi wearhente yokunciphisa amanzi ukongeza i-arhente yokugcina i-slump, kwaye emva koko usebenzise izixhobo ezikrwada ezikwisiza ukwenza uhlengahlengiso lomxube wokudibanisa ukulungelelanisa ilahleko yokudilika 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%, ukungcangcazela kwekhonkrithi akuphalazi igazi, kwaye wenze imizekelo yekhonkrithi nge-28-day compressive force ukufikelela kumandla oyilo.
