Ochepetsa madzi nthawi zambiri amakhala anionic surfactants, ndipo omwe amagwiritsidwa ntchito kwambiri pamsika akuphatikizapo polycarboxylic acid based reduction agents, naphthalene based reduction agents, etc. , kuonjezera mphamvu ya konkire, ndi kuchepetsa kuchitika kwa ming'alu. Amagwira ntchito yofunikira pakuwongolera magwiridwe antchito a konkriti. Komabe, zosakaniza za konkire zosakanizidwa ndi zochepetsera madzi zimatha kukumana ndi zovuta monga kumamatira ku thanki ndi malo onama. Pofuna kupewa kupezeka kwa mavuto osiyanasiyana, Freeman adzasanthula zomwe zimayambitsa ndi njira zothetsera mavutowo m'modzim'modzi.

一. Kukhoza kumamatira chodabwitsa:
Chodabwitsa: Mbali ina ya matope a simenti imamatira pakhoma la silinda yosakaniza, zomwe zimapangitsa kuti konkire iwonongeke komanso kuchepa kwa phulusa, zomwe zimapangitsa konkriti yomata.
Kusanthula zifukwa:
Kumamatira konkire nthawi zambiri kumachitika mukawonjezera zochepetsera ndi zochepetsera madzi, kapena zosakaniza za ng'oma zokhala ndi ma axial m'mimba mwake ofanana.
Terms of kuthetsa:
(1) Yang'anirani nthawi yake pakuyeretsa ndikuchotsa konkire yotsala;
(2) Choyamba, onjezerani zophatikizira ndi madzi kuti musakanize, kenaka yikani simenti, madzi otsalira, ndi chochepetsera madzi kuti musakanizire;
(3) Gwiritsani ntchito chiŵerengero chachikulu cha shaft m'mimba mwake kapena chosakaniza chokakamiza.

二.Pseudo coagulation phenomenon
Chodabwitsa: Konkire ikachoka pamakina imataya madzi ake mwachangu ndipo imatha kutsanuliridwa.
Kusanthula zifukwa:
(1) Kusakwanira kashiamu sulfate ndi gypsum mu simenti kumabweretsa mofulumira hydration kashiamu aluminiyamu;
(2) Wochepetsera madzi ali ndi vuto losasinthika ku mtundu uwu wa simenti;
(3) Pamene zomwe zili mu triethanolamine zimaposa 0.05-0.1%, kukhazikitsidwa koyambirira kumakhala kofulumira koma osati komaliza.
Terms of kuthetsa:
(1) Sinthani mtundu wa simenti;
(2) Ngati n'koyenera, kusintha admixtures ndi kuchita wololera compounding;
(3) Onjezani gawo la Na2SO4 pazosakaniza.
(4) Chepetsani kutentha kosakaniza
