Mu matope, cellulose ether imagwira ntchito yosunga madzi, kukhuthala, kuchedwetsa mphamvu ya madzi a simenti, komanso kukonza magwiridwe antchito omanga. Kutha kusunga madzi bwino kumapangitsa kuti madzi a simenti akhale okwanira, kumatha kukulitsa kukhuthala kwa madzi a matope onyowa, kuwonjezera mphamvu yolumikizirana ya matope, ndikusintha nthawi. Kuwonjezera cellulose ether ku matope opopera makina kungathandize kukonza kupopera kapena kupopera komanso mphamvu ya kapangidwe ka matope. Cellulose imagwiritsidwa ntchito kwambiri ngati chowonjezera chofunikira mu matope osakanikirana kale. Potengera gawo la zipangizo zomangira mwachitsanzo, cellulose ether ili ndi zinthu zabwino kwambiri monga kukhuthala, kusunga madzi, komanso kuchedwa. Chifukwa chake, cellulose ether ya zinthu zomangira imagwiritsidwa ntchito kwambiri kukonza kupanga matope osakanikirana kale (kuphatikiza matope osakanikirana bwino ndi matope osakanikirana ouma), PVC resin, ndi zina zotero, utoto wa latex, putty, ndi zina zotero, kuphatikiza magwiridwe antchito a zinthu zomangira.
Cellulose imatha kuchedwetsa njira yothira madzi ya simenti. Cellulose ether imapatsa matope zinthu zosiyanasiyana zothandiza, komanso imachepetsa kutentha kwa simenti koyambirira komanso imachepetsa njira yothira madzi ya simenti. Izi sizoyenera kugwiritsa ntchito matope m'malo ozizira. Zotsatirazi zimayambitsidwa ndi kuyamwa kwa mamolekyu a cellulose ether pazinthu zothira madzi monga CSH ndi ca(OH)2. Chifukwa cha kuchuluka kwa kukhuthala kwa yankho la pore, cellulose ether imachepetsa kuyenda kwa ma ayoni mu yankho, motero imachedwetsa njira yothira madzi. Pamene kuchuluka kwa cellulose ether mu mineral gel zinthu kukwera, zotsatira za kuchedwa kwa madzi zimaonekera kwambiri. Cellulose ether sikuti imangochedwetsa kukhazikitsa, komanso imachedwetsa njira yolimbitsira ya simenti. Zotsatira za kuchedwa kwa cellulose ether sizimangodalira kuchuluka kwake mu mineral gel system, komanso kapangidwe ka mankhwala. Pamene methylation ya HEMC ili pamwamba, zotsatira za kuchedwa kwa cellulose ether zimakhala bwino. Chiŵerengero cha kusintha kwa hydrophilic kupita ku kusintha kwa madzi. Zotsatira za kuchedwa zimakhala zolimba. Komabe, kukhuthala kwa ether ya cellulose sikukhudza kwambiri kayendedwe ka madzi a simenti.
Pamene kuchuluka kwa hydroxypropyl methylcellulose ether kunawonjezeka, nthawi yoyika matope inakula kwambiri. Pali ubale wabwino wosagwirizana ndi mzere pakati pa nthawi yoyika matope ndi kuchuluka kwa matope a cellulose ether, komanso ubale wabwino pakati pa nthawi yoyika yomaliza ndi kuchuluka kwa matope a cellulose ether. Tikhoza kuwongolera nthawi yogwirira ntchito matope posintha kuchuluka kwa matope a cellulose ether.
