Chikoka cha matope zili mchenga papolycarboxylate superplasticizernthawi zambiri zimapha, zomwe zimawonekera kwambiri kuposa mndandanda wa naphthalene ndi aliphatic superplasticizers. Pamene matope akuwonjezeka, ntchito ya konkire imapangidwa bwino powonjezera kuchuluka kwapolycarboxylate superplasticizer, nthawi zina ndi theka la khama, ndipo nthawi zina magazi amayamba kutuluka madzi asanafike. Pamene matope ophatikiza bwino amaposa 5%, kuchepetsa madzi a konkire osakanikirana ndipolycarboxylate superplasticizeradzachepa, ndipo ngakhale
fluidity idzatayika kotheratu, ndipo kusungika kocheperako kudzakhalanso koyipa. Pazinthu za ufa wamwala, m'pofunikanso kuchita mayesero a pa siteti kangapo kuti muzitha kulamulira zomwe zili mu ufa wa mwala, kuti chidziwitso chikhoza kulamuliridwa bwino, madzi a konkire atha kutsimikiziridwa, ndi ntchito ya konkire akhoza wokometsedwa.
Pavuto lamakono la matope, pali njira zingapo zothetsera mavuto:
(1) Wonjezerani mlingo kapena kuonjezera chiwerengero cha kutsika pang'onopang'ono-kusunga wothandizila, koma kulamulira kuchuluka kwa kupewa chikasu, magazi, tsankho, tagwira pansi ndi konkire retarding nthawi yaitali kwambiri;
(2) Sinthani kuchuluka kwa mchenga kapena kuwonjezera kuchuluka kwa mpweya. Pamaziko a kuonetsetsa kuti ntchito yabwino ndi mphamvu, kuchepetsa mlingo mchenga kapena kuwonjezera mpweya-entraining kuchuluka kukwaniritsa cholinga kuonjezera madzi aulere ndi slurry kuchuluka kwa dongosolo konkire. kusintha katundu wa konkire;
(3) Onjezani moyenerera kapena kusintha zigawozo kuti muthetse vutoli. Mayesero asonyeza kuti kuwonjezera mlingo woyenerera wa sodium metabisulfite, sodium thiosulfate, sodium hexametaphosphate, ndi sodium sulfate ku chochepetsera madzi kungachepetse chikoka cha matope pa konkire kumlingo wakutiwakuti.
Zoonadi, njira zomwe zili pamwambazi sizingathetse mavuto onse a matope, ndipo zotsatira za matope pa kukhazikika kwa konkire zimafunikira kufufuza kwina, kotero njira yofunikira ndiyo kuchepetsa matope a zipangizo.
