Kungani usebenzise i-RDP ngokhonkolo

I-RDP, noma i-polymerverible polymer powder, isengezo esivamile esisetshenziswa ukwakhiwa kokhonkolo ngezizathu ezahlukahlukene. Lezi zithangezo zingama-polymer powders angahlakazeka emanzini ukuze akhe ifilimu ngemuva kokomiswa. Nakhu ukuthi i-RDP isetshenziswa kukhonkolo:

1. Ukusebenza okwenziwe ngcono kanye nobumbano: I-RDP isiza ukuthuthukisa ukusebenziseka kanye nokuhlangana kokuhlanganiswa kokhonkolo. Isebenza njenge-distriant, esiza ekuhlakazeni izinhlayiya zosekhukhwini nezinye izengezo kuyo yonke le ngxube. Lokhu kuphumela ku-homogeneous futhi kube lula ukuhlanganiswa kokhonkolo.
2. Ukutholwa kwamanzi okuncishisiwe: ukhonkolo oqukethe i-RDP ngokujwayelekile ekhombisa ukuncishiswa kwezakhiwo ezitholakale amanzi. Ifilimu ye-polymer eyakhiwe yi-RDP isiza ukusayina ama-pores kanye nama-capillaries ngaphakathi kwe-matrix ekhonkolo, ukunciphisa ukuvumela nokuvimbela ukungena kwamanzi. Lokhu kubaluleke kakhulu ekuthuthukiseni ukuqina kanye nokumelana nezinhlaka zokhonkolo eziya enhlangothini ehlobene nomswakama.
3. Amandla aguquguqukayo athuthukisiwe kanye ne-Tlensile: Ukungezelelwa kwe-RDP kuya kokwenziwa kokhonkolo kungakhulisa izakhiwo zamandla eziguqukayo nezentengiselwano zokhonkolo welapha. Ifilimu ye-polymer eyakhiwe ngesikhathi se-hydration ithuthukisa isibopho phakathi kwezinhlayiya zokwenza usimende kanye nama-aggregates, okuholela ku-matrix yekhonkolo enamandla futhi enamandla kakhonkolo.
4. Ukunamathela okuthuthukisiwe kanye nokubopha: I-RDP ikhuthaza ukunamathela okungcono nokubopha phakathi kwezingqimba zokhonkolo kanye nezindawo zokubopha. Lokhu kunzuzo ikakhulukazi ekusetshenzisweni nasekuvuselelekeni kabusha kwezicelo, lapho ukumbondelana ngokhonkolo kudingeka kubunguswe ngempumelelo ezindaweni ezikhona ukhonkolo noma ama-substrates.
5. Ukuncipha kwe-shrinkage kanye nokuqhekeka: I-RDP isiza ukunciphisa ubungozi be-shrinkage yepulasitiki nokuqhekeka ngokhonkolo. Ifilimu ye-polymer eyakhiwe nge-RDP isebenza njengesithiyo ekulahlekelweni komswakama ngesikhathi sezigaba zokuqala ze-hydration, ukuvumela ukhonkolo ukuthi welapha ngokulinganayo futhi unciphise ukuthuthukiswa kokuqhekeka okuningana.
6. Ukumelana kwe-freeze-thaw okuthuthukile: ukhonkolo oqukethe imibukiso ethuthukisiwe ethuthukisiwe emijikelezweni ye-freeze-thaw. Ifilimu ye-polymer eyakhiwe yi-RDP isiza ukunciphisa ukuvumela kwe-matrix kakhonkolo, ukunciphisa ukufakwa kwamanzi kanye nethuba lokulimala kwama-freeze-thaw ezimweni sezulu ezibandayo.
7. Ukusebenza okwenziwe ngcono ezimeni ezinzima: I-RDP ingathuthukisa ukusebenziseka kokuhlanganiswa kokhonkolo ezimweni ezinzima zemvelo, njengokushisa okuphezulu noma umswakama ophansi. Ifilimu ye-polymer eyakhiwe yi-RDP isiza ukugcoba izinhlayiya zosekhukhwini, kunciphise ukungezwani futhi kusiza ukugeleza nokubekwa kwe-conkcrete mix.

Ukusetshenziswa kwe-RDP ekwakhiweni kokhonkolo kunikeza izinzuzo eziningana, kufaka phakathi ukukhiqizwa okuthuthukisiwe, ukuncishiswa kwamanzi okuncishisiwe, amandla athuthukisiwe nokuqina, ukuncipha, ukukhiqizwa okuthuthukile okuthuthukile, kanye nokusebenza okuthuthukile kwezimo ezinzima. Lezi zinzuzo zenza i-RDP ibe yisengezo esibalulekile sokwenza kahle ukusebenza nokuqina kokhonkolo ezisetshenziselwa ezahlukahlukene zokwakha.
