Iarhente yokunciphisa amanzi yePolycarboxylate inconywe kakhulu luluntu lobunjineli boshishino ngenxa yedosi yayo ephantsi, izinga eliphezulu lokunciphisa amanzi kunye nelahleko encinci yekhonkrithi, kwaye ikwaqhubele phambili uphuhliso olukhawulezayo lwetekhnoloji yekhonkrithi.

Impembelelo yomgangatho wesanti eyenziwe ngumatshini kunye nokulungelelaniswa kwe-admixture kumgangatho wekhonkrithi:

(1) Xa uvelisa isanti eyenziwe ngumatshini, umxholo womgubo welitye kufuneka ulawulwe ngokungqongqo malunga ne-6%, kwaye umxholo wodaka kufuneka ube ngaphakathi kwe-3%. Umxholo we powder wamatye uyongezwa kakuhle kwisanti engapheliyo eyenziwe ngumatshini.

(2) Xa ulungiselela ikhonkrithi, zama ukugcina umlinganiselo othile womgubo welitye kwaye wenze ukuhlelwa ngokufanelekileyo, ngakumbi isixa esingaphezu kwe-2.36mm.

(3) Ngaphantsi kwesiseko sokuqinisekisa ukomelela kwekhonkrithi, lawula umlinganiselo wesanti kwaye wenze umlinganiselo wegrabile enkulu kunye nencinci ibe nengqiqo. Isixa segrabile encinci sinokunyuswa ngokufanelekileyo.

(4) Isanti yomatshini ohlanjiweyo igalelwe imvula kwaye isuswe udaka ngeeflocculants, kwaye isixa esikhulu se-flocculants siya kuhlala kwisanti egqityiweyo. Ii-flocculants ezinobunzima be-molecular high zinempembelelo enkulu ngokukodwa kwiinciphisi zamanzi. Ngelixa uphinda-phinda idosi ye-admixture, ubumanzi bekhonkrithi kunye nelahleko yokudilika nazo zinkulu kakhulu.

Impembelelo ye-admixtures kunye nokulungelelaniswa kwe-admixture kumgangatho wekhonkrithi:

(1) Yomeleza ukubonwa kothuthu lwempukane emhlabeni, ubambe utshintsho kwilahleko yayo yokutshisa, kwaye unike ingqwalasela enkulu kumlinganiselo wemfuno yamanzi.

(2) Inani elithile le-clinker linokongezwa kwi-fly ash yomhlaba ukwandisa umsebenzi walo.

(3) Akuvumelekanga ngokungqongqo ukusebenzisa izinto ezifunxa kakhulu emanzini ezifana nelahleko yamalahle okanye i-shale ukugalela uthuthu lwempukane.

(4) Inani elithile leemveliso ezinezithako zokunciphisa amanzi zingongezwa kuthuthu lwempukane yomhlaba, enempembelelo ethile ekulawuleni umlinganiselo wemfuno yamanzi. Umgangatho wezinto ezahlukeneyo unempembelelo ecacileyo ngokukodwa kwimeko yekhonkrithi, kwaye ukusombulula ingxaki yokulungelelanisa kufuna inkqubo yohlalutyo olucacileyo.
