Kafukufuku pa mfundo yogwirira ntchito ya ufa wamatope ndi polycarboxylic acid kuchepetsa madzi:
Nthawi zambiri amakhulupirira kuti chifukwa chachikulu chomwe ufa wamatope umakhudza konkire wothira lignosulfonate ndi naphthalene-based reduction agents of water reduction ndi mpikisano wa adsorption pakati pa ufa wamatope ndi simenti. Palibe kulongosola kogwirizana pa mfundo yogwirira ntchito ya ufa wamatope ndi polycarboxylic acid yochepetsera madzi.
Akatswiri ena amakhulupirira kuti mfundo yogwira ntchito ya ufa wamatope ndi wochepetsera madzi ndi yofanana ndi simenti. Wothandizira kuchepetsa madzi amadsorbed pamwamba pa simenti kapena ufa wamatope ndi magulu a anionic. Kusiyanitsa ndiko kuti kuchuluka ndi mlingo wa adsorption wa wothandizira kuchepetsa madzi ndi matope ufa ndi wochuluka kwambiri kuposa simenti. Pa nthawi yomweyo, mkulu enieni pamwamba m'dera ndi wosanjikiza dongosolo la dongo mchere komanso kuyamwa madzi ochulukirapo ndi kuchepetsa madzi aulere mu slurry, zomwe zimakhudza mwachindunji ntchito yomanga konkire.
Zotsatira za minerals zosiyanasiyana pakugwira ntchito kwa ochepetsa madzi:
Kafukufuku akuwonetsa kuti matope okhawo omwe ali ndi kukula kwakukulu komanso kuyamwa kwamadzi ndi omwe angakhudze kwambiri magwiridwe antchito komanso pambuyo pake makina a konkriti.
Matope adongo wamba pamagulu ambiri amaphatikiza kaolin, illite ndi montmorillonite. Mtundu womwewo wa mankhwala ochepetsera madzi uli ndi zomverera zosiyana ndi matope amatope omwe ali ndi zolemba zosiyanasiyana za mchere, ndipo kusiyana kumeneku n'kofunika kwambiri pa kusankha mankhwala ochepetsera madzi ndi chitukuko cha matope oletsa madzi oletsa matope ndi odana ndi matope.
Zotsatira za ufa wamatope pazinthu za konkriti:
Kugwira ntchito kwa konkire sikungokhudza kupanga konkire, komanso kumakhudzanso mphamvu zamakina pambuyo pake komanso kulimba kwa konkire. Kuchuluka kwa tinthu tating'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono, timafota tikauma ndikukula pakanyowa. Pamene matope akuwonjezeka, kaya ndi polycarboxylate yochepetsera madzi kapena naphthalene yochepetsera madzi, idzachepetsa kuchepetsa madzi, mphamvu, ndi kugwa kwa konkire. Kugwa, etc., kubweretsa kuwonongeka kwakukulu kwa konkire.
