Wothandizira kuchepetsa madzi a Polycarboxylate adayamikiridwa kwambiri ndi gulu laumisiri wamakampani chifukwa cha kuchepa kwake, kuchuluka kwa madzi ochepera komanso kutsika pang'ono kwa konkriti, komanso kwathandizira kukula mwachangu kwaukadaulo wa konkriti.

Chikoka cha mchenga wopangidwa ndi makina komanso kusinthasintha kosakanikirana pamtundu wa konkriti:

(1) Popanga mchenga wopangidwa ndi makina, ufa wamwala uyenera kuyendetsedwa mosamalitsa pafupifupi 6%, ndipo matope ayenera kukhala mkati mwa 3%. Zomwe zili mu ufa wamwala ndizowonjezera bwino pamchenga wopangidwa ndi makina osapitirira.

(2) Pokonzekera konkire, yesetsani kusunga kuchuluka kwa ufa wamwala ndikupangitsa kuti chiwerengerocho chikhale choyenera, makamaka kuchuluka kwa pamwamba pa 2.36mm.

(3) Pansi pa malo owonetsetsa mphamvu ya konkriti, sungani chiŵerengero cha mchenga ndikupanga chiŵerengero cha miyala yaing'ono ndi yaikulu. Kuchuluka kwa miyala yaying'ono kumatha kuonjezedwa moyenera.

(4) Mchenga wamakina otsukidwa umakhala wocheperako komanso wothira matope ndi ma flocculants, ndipo ma flocculants ambiri amakhalabe mumchenga womalizidwa. High molecular weight flocculants zimakhudza kwambiri zochepetsera madzi. Ngakhale kuwirikiza kawiri mlingo wa admixture, kusungunuka kwa konkire ndi kutayika kwakukulu kumakhalanso kwakukulu.

Chikoka cha ma admixtures ndi kusinthika kwa admixture pamtundu wa konkriti:

(1) Limbikitsani kuzindikira phulusa la ntchentche, mvetsetsani kusintha kwa kuyatsa kwake, ndipo samalani kwambiri ndi chiŵerengero cha madzi.

(2) Kuchuluka kwa clinker kumatha kuwonjezeredwa ku phulusa la ntchentche kuti liwonjezere ntchito yake.

(3) Ndizoletsedwa kugwiritsa ntchito zinthu zomwe zimakhala ndi madzi okwera kwambiri monga malasha gangue kapena shale pogaya phulusa la ntchentche.

(4) Kuchuluka kwa zinthu zokhala ndi zosakaniza zochepetsera madzi zitha kuwonjezeredwa ku phulusa la ntchentche, zomwe zimakhala ndi zotsatirapo zake pakuwongolera chiŵerengero cha madzi. Ubwino wa zipangizo zosiyanasiyana umakhudza makamaka zoonekeratu pa dziko konkire, ndi kuthetsa vuto kusinthasintha amafuna mwatsatanetsatane kusanthula ndondomeko.
