M'zaka zaposachedwa, makampani omanga adawona mosintha kwambiri kuti agwiritse ntchito konkriti yayitali kuti akwaniritse zofunikira zamakono zomangamanga zamakono. Chimodzi mwazinthu zofunikira kwambiri za konkriti zoyenda kwambiri ndi binder, zomwe zimamangiriza tinthu tating'onoting'ono kuti mupange matrix olimba komanso olimba. Mwa mitundu yosiyanasiyana ya zomata, kugwiritsa ntchito zomatira kwa polymeric kwakhala kutchuka chifukwa chokhoza kupereka zofuna zake monga kukhazikika kowonjezereka.
Chimodzi mwazomwe zimagwiritsidwa ntchito kwambiri polymer coders monkriti kwambiri ndi ntchentche (wobwezeretsa poling (wobwezeretsedwa)) Manger a RDP polymer ali ndi ufa wouma womwe umatha kusakanizidwa mosavuta ndi zosakaniza zina kuti zisankhidwe ndi kusinthasintha ndi kuthetsa madzi. Kuonjezera mabowo a RDP polowera konkriti makamaka makamaka pakugwiritsa ntchito komwe konkriti amayembekezeka kukhala ndi zipsinjo zomwe zikuyenera kukhala ndi zovuta zambiri kapena kuzungulira pafupipafupi.
Chimodzi mwazinthu zabwino kwambiri za zomatira za rdp polymer zimagwirira ntchito bwino. Magombe a RDP polymer ali ndi othandizira mankhwala omwe amawathandiza kutsatira tinthu tating'onoting'ono komanso zina mwa zosakaniza zosakaniza konkriti. Izi zimapangitsa kuti matrix olimba komanso okhazikika, popewa zowonongeka kuchokera kunkhondo zakunja monga ma freeze-thaw.
Phindu lina la nthambi ya rdp polymer ndi kuthekera kwawo kowonjezera kusinthasintha kwa zosakaniza ndi konkriti. Zisakanizo zachikhalidwe nthawi zambiri zimakhala zopanda bongo komanso zowoneka kuti zikuwoneka kuti zikuwoneka bwino kapena kusintha kutentha. Magombe a RDP polymer amatha kusinthidwa kuti apange madigiri osiyanasiyana osinthika, kulola kusakaniza konkriti kukhala bwino kupirira zipsinjo zosafunikira. Kusintha kumeneku kumachepetsa chiopsezo cha kunenepa kapena mitundu ina ya zowonongeka pomanga kapena kugwiritsa ntchito.
Kuphatikiza pa kupereka chitamba chachikulu komanso kusinthasintha, rdp polymes kumalumikizananso ndi chinyezi. Zojambula ku konkriti zomwe zimadziwika ndi madzi kapena chinyezi kwa nthawi yambiri imatha kudwala, kuphatikizapo kuwonongeka, kuweta ndi kutukuka. Mangani a RDP polymer amakhala ndi othandizira omwe amathandizira kubweza chinyezi, kuchepetsa chiopsezo cha mavutowa ndikuwongolera magwiridwe antchito a konkriti.
Kugwiritsa ntchito ma polymer omatira kumalinso ochezeka. Mosiyana ndi zikwangwani zachikhalidwe, zomwe zimafuna simenti yambiri ya Porton, gwero lalikulu la mpweya, ma colymer a rdp polyme amatha kugwiritsa ntchito zochepa kuti akwaniritse gawo lomweli. Izi zimachepetsa mawonekedwe a kaboni konkriti ndipo imathandizira kuchepetsa mphamvu zachilengedwe.
Ngakhale ali ndi zabwino zambiri, pali zovuta zina zokhudzana ndi kugwiritsa ntchito ma polyr comber ku konkriti. Chimodzi mwazinthu zovuta kwambiri ndikufunika kuwongolera mlingo ndi kusakaniza kwa ma polymer omangirira kuti awonetsetse bwino. Chingwe chochepa kwambiri chimapangitsa kuti chizolowedwe chochepetsedwa ndi kulimba, pomwe nthambi yambiri imapangitsa kuti mphamvu zochepetsetse komanso kuchepetsedwa. Chifukwa chake, ndikofunikira kugwira ntchito ndi wogwirizanitsa konkire yemwe amamvetsetsa zomwe zimapangitsa kuti katundu wa ntyp azitha ndipo amatha kuthandiza kukonza zomwe amagwiritsa ntchito.
Pali maubwino ambiri ogwiritsa ntchito ma polym polyme comprer konkire kwambiri. Zimawonjezera kulimba komanso kusinthasintha kwa kusakaniza konkriti, kumathandizanso kukana kwake ku chinyezi, ndipo ali ndi mphamvu yochepa kwambiri kuposa mitundu yachikhalidwe cha konkriti. Ngakhale kugwiritsa ntchito kwawo kumabweretsa zovuta, kusakaniza mosamala ndi kusakaniza kumatha kukhala ndi zotsatira zabwino ndikupangitsa kuti chilengedwe champhamvu komanso chanthawi yayitali komanso chosatha. Zochita za RDP polymer ndizosasangalatsa kwa iwo omwe akufuna kupanga ma contreretive zojambula zomwe zimatha kupirira mikhalidwe yovuta komanso yodalirika pakapita nthawi.
