Pamene simenti imasakanikirana ndi madzi, chifukwa chokopeka mogwirizana pakati pa mamolekyulu a simenti pa tebulo mu njira ya michere, ndi mayanjano ena a madzi othetsa kanema pambuyo pa mchere wa simenti ndi hydrate. Zophatikizidwa, kutime simenti ikhale yopuma. Madzi ambiri oyambitsa amakulungidwa polota, kuti mawonekedwe a tinthu tating'onoting'ono asalumikizidwe mokwanira ndi madzi, zomwe zimapangitsa kuti kugwiritsidwa ntchito kwamadzi komanso kulephera kukwaniritsa ntchito yomanga.

Pambuyo powonjezera superplastic, gulu la hydrophobic la superpuliccise molekyuricliser padera la simenti za tinthu tating'onoting'ono timakhala ndi mlandu womwewo. Mothandizidwa ndi magetsi, tinthu tating'onoting'ono timasiyanitsidwa ndi wina ndi mnzake, ndipo kupatula malo opumira simenti asokonezedwa. Kumbali inayo, madzi aulere pakukongoletsa kwa simenti slurry amamasulidwa, yomwe imawonjezera kulumikizana pakati pa tinthu ndi madzi, potero kuwonjezereka madzimadzi; Kuphatikiza apo, kufinya pakati pa tinthu tating'onoting'ono kumachulukitsa chifukwa cha kukula kwa filimu yamadzi yomwe idapangidwa pamwamba pa simenti. Awa ndi mfundo yomwe mankhwala othandiza madzi amachepetsa kugwiritsa ntchito madzi chifukwa cha Adsorption, kubalalika, kunyowa komanso kuthira mafuta.

Mfundo Yophunzitsira: Mwachidule, madzi ochepetsa madzi nthawi zambiri amakhala okonda kwambiri kuti Adsors pansi pa simenti tinthu, ndikupangitsa tinthu tamagetsi. Tinthu tating'onoting'ono timatulutsana chifukwa cha magetsi omwewo, kuti madzi owonjezera a simenti amabalalitsidwa, ndipo madzi owonjezera pakati pa tinthu tamasulidwa kuti muchepetse madzi. Komabe, mutatha kuwonjezera madzi kuchepetsa mankhwala, filimu ya Adsorption imapangidwa pamwamba pa simenti, zomwe zimakhudza kuthamanga kwa simenti, kumapangitsa kukula kwa cmentart kukhala wangwiro, ma netiweki ndi ochulukirapo Kuwala, ndikusintha mphamvu ndi kachulukidwe kakang'ono ka simenti.

Pamene kutsika kwa konkriti ndikofanana, kuphatikiza komwe kungachepetse kumwa madzi konkriti. Madzi ochepetsa madzi amagawidwa m'madzi wamba amachepetsa wothandizila wa madzi ndi wothandiza. Omwe ali ndi kuchepa kwa madzi ochepera kapena ofanana ndi 8% amatchedwa kuti madzi wamba amadzitcha, ndipo omwe ali ndi madzi ochepetsa madzi oposa 8% amatchedwa kuti madzi abwino kwambiri. Malinga ndi zovuta zosiyanasiyana zomwe superplastiction zitha kubweretsa konkriti, zimagawika poyera ndi mphamvu zapamwamba komanso zapamwamba za mpweya.

Mwa kuyambitsa ntchito yowonjezera madzi opulumutsa madzi kuti asindikizetse othandizira, timamvetsetsa bwino za vuto lowonjezeranso mankhwalawa pomanga wothandizira. Mwanjira yosavuta, gawo la madzi kuchepetsa wothandizira limakhala logwira ntchito, lomwe lingapangitse simenti ya simenti iperekenso ma elekitirodi omwewo, ndikumasulira madzi pakati pazinthu zomwezo zimayimitsa, ndikuchepetsa madzi.
