Udindo wa Ascretireturession ndikuwongolera katundu wa konkriti ndikuchepetsa kuchuluka kwa zinthu za cerementi. Chifukwa chake, kulembetsa konkriti kumagwiritsidwa ntchito kwambiri m'minda yomanga zosiyanasiyana.
Limagwirira ntchito ya kugwirizanitsa kwa Connette:
Ma antanixentery ogwiritsa ntchito Naythalene opangidwa ndi polycaxtlate-polcaxtlation ndi mankhwala olemera olemera (nthawi zambiri 1500-10000) ndipo ali m'gulu la okonda.
Molekyu ya zowonjezera zimakhala ndi kapangidwe kake kambiri, kutsiriza kumali ndi lipophilic. Pambuyo pa zochulukitsa pambuyo posungunuka m'madzi, imatha kusewera ntchito zosiyanasiyana monga kubalalitsa, kunyowetsa, kunyowa, kuluma ndikutsuka ndikuchepetsa nkhawa.
A. Adsorption-Batani
Madzi a kusakaniza konkriti amatengera kuchuluka kwa madzi aulere mu konkriti. Pambuyo pa kuphatikizika kumawonjezeredwa konkritiyo, tinthu tating'onoting'ono tinalimbitsena chifukwa cha adsorption ya chitsogozo cha mamolekyu osakaniza pansi pa ma mamolekyusi osaneneka pakati pawo. Zotsatira zake, simenti yodzitayidwa imawonongedwa, ndipo madzi ambiri aulere amasulidwa, omwe amawonjezera madzi ambiri osakaniza konkriti.
B. Kunyowa
Chifukwa cha makonzedwe a mamonakyulu osakaniza pamtunda wa simenti tinthu tating'onoting'ono, filimu yamadzi yotheradi imapangidwa. Kanemayu filimuyi imawonjezera malo ochezera pakati pa tinthu tambiri ndi madzi, ndipo imakhala ndi mphamvu inayake yonyowa mbali inayo. Chifukwa chake simentiyo ndi hydrated kwathunthu komanso mphamvu ya simenti imawonjezeka mwachangu.
Ntchito Zoyambira Zoyambira Adretete:
1. Popanda kuchepetsa kumwa madzi, kuchuluka kwa madziwo sikusintha, zomwe zimathandizanso kugwirira ntchito konkriti zatsopano ndikusintha madzimadzi; Chifukwa cha malo owonjezereka pakati pa tinthu ndi madzi, simenti ndi hydrated kwathunthu, ngakhale kuchuluka kwa magulu olumikizira madzi, mphamvu ya konkriti nthawi zambiri imakhala ndi kusintha kwina.
2. Potengera ntchito yosunga ntchito inayake, muchepetse kumwa madzi, kuchepetsa kuchuluka kwa madzi, ndikusintha mphamvu ya konkriti.
3. Potengera kulimba mtima, sinthani kuchuluka kwa zinthu za cemimer, muchepetse kugwiritsa ntchito madzi, kusunga chingwe chosasinthika, ndikupulumutsa simenti ndi zina zosokoneza.
Momwe Mungapangire Kuchita bwino ndikugwiritsa ntchito ma andirete a Conrote:
Kulandila moyenera komanso kugwiritsa ntchito akwati kumatha kupanga mtengo wapatali wachuma komanso luso. Sizingasinthe mphamvu ya konkriti, komanso kuchepetsa mtengo wa racete wosakaniza.
Njira yodziwikitsayi ili motere:
a. Lumikizani
Kuyesedwa ndi kuyesa kwa zizindikiro zosiyanasiyana za kuvomerezeka ndi cholumikizira musanagule zokambirana. Kudzera mayeso, miyezo yeniyeni ya zisonyezo zosiyanasiyana za kuphatikizika ziyenera kutsimikizika. Kuphatikiza zofunikira za ma Admictimes, kuchepetsa madzi, kachulukidwe, madzi ocheperako, madzi ochepetsa, matembenuzidwe amatembenuzidwe. Amanenedwa kuti kuchepa kwa madzi konkriti kugwiritsidwa ntchito ngati chisonyezo chofunikira kuti muyeze ma adminitures.
b. Kupeza
Pambuyo pa kusinthika koyenera kwa adntactive mosavomerezeka, zokambirana zogulira zimatha kuyamba. Amanenedwa kuti opanga omwe amapanga ayenera kuyitanitsa ndalama malinga ndi miyezo yeniyeni yotsimikizika ndi mayeso. Pamalo omwe amapereka mawonekedwe osakanikirana ndi otsika kuposa zofunikira zothandizira, wogulitsa adzatsimikizika molingana ndi mfundo yopambana kuti apange phindu.
Nthawi yomweyo, kusankha kwa opanga ma CRRETE ndi kuchuluka. Ngati chisonyezo chimodzi chowunikira.
c. Cholumikizira chovomerezeka
Malo osakanikirana ayenera kuyesa ma addictures asanagwiritsidwe ntchito Ndikulimbikitsidwa kusiyanitsa pakati pa zisonyezo zazikuluzikulu komanso zowerengera. Kudzera muzochita nthawi yayitali, wolemba amakhulupirira kuti zisonyezo zachinsinsi za ma Adntactures ndi njira yochepetsera madzi (matope) ndi kungochepetsa madzi; Zizindikiro zowerengera ndizotupa (mphamvu yokoka), zolimba ndi madzi amtundu wa simenti. Chifukwa cha nthawi yoyesa, zizindikiro zomwe zimayesedwa mu ulalo wovomerezedwa ndi kachulukidwe, madzi amtundu wa simenti ndi kuchuluka kwa madzi ndi madzi ochepetsa (matope).
