Kutheni Usebenzisa iRDP kwiConcrete

I-RDP, okanye i-Redispersible Polymer Powder, yinto eyongeziweyo eyongeziweyo esetyenziselwa ukwakhiwa kwekhonkrithi ngenxa yezizathu ezahlukeneyo.Ezi zongezo ziyi-polymer powders ezinokuthi zisasazwe emanzini ukwenza ifilimu emva kokumisa.Nasi isizathu sokuba i-RDP isetyenziswe kwikhonkrithi:

1. UkuPhuculwa kokuSebenza kunye nokuBambisana: i-RDP inceda ukuphucula ukusebenza kunye nokudityaniswa kwemixube yekhonkrithi.Isebenza njenge-dispersant, inceda ekusasazeni iinqununu zesamente kunye nezinye izongezo kulo lonke umxube.Oku kubangela umxube wekhonkrithi olinganayo kwaye kulula ukuwuphatha.
2. Ukufunxwa kwaManzi okuNcitshisiweyo: Ikhonkrithi equlethe iRDP idla ngokubonisa iimpawu ezincitshisiweyo zokufunxa amanzi.Ifilimu ye-polymer eyenziwe yi-RDP inceda ukutywina i-pores kunye ne-capillaries ngaphakathi kwe-matrix yekhonkrithi, ukunciphisa ukunyanzeliswa kunye nokuthintela ukungena kwamanzi.Oku kubaluleke ngakumbi ekwandiseni ukuqina kunye nokuxhathisa kwezakhiwo zekhonkrithi ukuwohloka okunxulumene nokufuma.
3. I-Flexural and Tensile Strength eyomeleziweyo: Ukongezwa kwe-RDP kwimixube yekhonkrithi kunokuphucula iimpawu zamandla e-flexural kunye ne-tensile yekhonkrithi enyangisiweyo.Ifilimu ye-polymer eyenziwe ngexesha le-hydration iphucula i-bond phakathi kwamaqhekeza e-samente kunye ne-aggregates, okukhokelela kwi-matrix yekhonkrithi eqinileyo kunye neyomelele.
4. Ukuphuculwa kokubambelela kunye nokuBonda: I-RDP ikhuthaza ukunamathela okungcono kunye nokudibanisa phakathi kweengqimba zekhonkrithi kunye ne-substrates.Oku kuluncedo ngakumbi ekulungiseni nasekuhlaziyeni izicelo, apho ulwaleka lwekhonkrithi okanye iipetshi kufuneka zidityaniswe ngokufanelekileyo kumphezulu okhoyo wekhonkrithi okanye isubstrates.
5. Ukuncitshiswa kwe-Shrinkage kunye ne-Cracking: i-RDP inceda ukunciphisa umngcipheko wokunciphisa iplastiki kunye nokuqhekeka kwekhonkrithi.Ifilimu ye-polymer eyenziwe yi-RDP isebenza njengesithintelo ekulahlekeni kokufuma ngexesha lamanyathelo okuqala okuhambisa amanzi, evumela ikhonkrithi ukuba iphilise ngokulinganayo kunye nokunciphisa ukuphuhliswa kokuqhekeka kwe-shrinkage.
6. Ukomelezwa kokumelana nokunyibilika komkhenkce: Ikhonkrithi equlethe i-RDP ibonisa ukuxhathisa okuphuculweyo kwimijikelo yokunyibilika komkhenkce.Ifilimu ye-polymer eyenziwe yi-RDP inceda ukunciphisa ukunyanzeliswa kwe-matrix yekhonkrithi, ukunciphisa ukungena kwamanzi kunye nokukwazi ukutshatyalaliswa kweqhwa kwiindawo ezibandayo.
7. UkuPhuculwa kokuSebenza kwiimeko ezinzima: I-RDP inokuphucula ukusebenza kwemixube yekhonkrithi kwiimeko ezinzima zokusingqongileyo, ezifana nokushisa okuphezulu okanye ukufuma okuphantsi.Ifilimu ye-polymer eyenziwe yi-RDP inceda ukugcoba amaqhekeza e-samente, ukunciphisa ukungqubuzana kunye nokuququzelela ukuhamba kunye nokubekwa komxube wekhonkrithi.

ukusetyenziswa kwe-RDP ekuqulunqweni kwekhonkrithi kunika iingenelo ezininzi, kubandakanywa ukuphuculwa kokusebenza, ukunciphisa ukufunxa kwamanzi, ukomeleza amandla kunye nokuqina, ukubambelela okuphuculweyo kunye nokudibanisa, ukunciphisa ukuncipha kunye nokuqhekeka, ukunyusa ukunyanzeliswa komkhenkce, kunye nokuphucula ukusebenza kwiimeko ezinzima.Ezi zibonelelo zenza i-RDP ibe sisongezo esixabisekileyo sokwandisa ukusebenza kunye nokuqina kwekhonkrithi kwizicelo ezahlukeneyo zokwakha.
