Impembelelo ye-Fiberglass kwi-Erosion Resistance ye-Recycled Concrete

Impembelelo ye-fiberglass ekuxhathiseni ukhukuliseko lwekhonkrithi esetyenzisiweyo ngokutsha (eyenziwe kwiiaggregates zekhonkrithi esetyenzisiweyo) sisihloko esinomdla obalulekileyo kwisayensi yezinto kunye nobunjineli boluntu. Ngelixa ikhonkrithi esetyenzisiweyo ibonelela ngokusingqongileyo kunye nezibonelelo zokurisayikilisha, iimpawu zayo zomatshini kunye nokuqina (umzekelo, ukuxhathisa ukhukuliseko) zisoloko zingaphantsi kunekhonkrithi eqhelekileyo. I-Fiberglass, njengeukuqinisa imathiriyeli, inokuphucula ukusebenza kwekhonkrithi esetyenzisiweyo ngokusebenzisa iindlela eziphathekayo kunye neekhemikhali. Nalu uhlalutyo oluneenkcukacha:

1. IiPropati kunye neMisebenzi yeI-Fiberglass

I-Fiberglass, i-inorganic non-metallic material, ibonisa ezi mpawu zilandelayo:
Amandla obunzima obuphezulu: Buyekeza umthamo ophantsi wekhonkrithi.
Ukumelana nokukhula: Ukumelana nohlaselo lwekhemikhali (umz., ii-ion zekloridi, iisulfates).
Ukuqina kunye nokumelana nokuqhekeka**: Iibhulorho ezincinci ukulibazisa ukwanda kweentanda kunye nokunciphisa ukungeneka.

2. UZinzo lweZiphene zeConcrete eRecycled

Iaggregates eziphinda zisetyenziswe kunye nencola yesamente eshiyekileyo kwindawo yazo zikhokelela ku:
Indawo yotshintsho oluphakathi kobuso obubuthathaka (ITZ): Unxulumano olungekho mgangathweni phakathi kweeaggregates ezisetyenzisiweyo kunye nentlama yesamente entsha, idala iindlela ezingenekayo.
Ukungatshoni okusezantsi: Izinto ezikhukulisekayo (umzekelo, iCl⁻, SO₄²⁻) zingena lula, zibangela ukuthotywa kwentsimbi okanye umonakalo omkhulu.
Ukunganyangeki kakuhle komkhenkce: Ukwandiswa komkhenkce kwiipore kubangela ukuqhekeka kunye nokuqhekeka.

3. IiNdlela zeFiberglass ekuPhuculeni ukuchasana nokukhukuliseka

(1) Izithintelo zoMzimba
I-Crack inhibition: Iifiber ezihlakazekileyo ngokulinganayo zibhula ii-microcracks, zithintela ukukhula kwazo kunye nokunciphisa iindlela ze-erosive agents.
Ukubumbana okuphuculweyo: IiFibers zigcwalisa i-pores, zehlisa i-porosity kwaye zicotha ukusasazwa kwezinto ezinobungozi.

(2) Ukuzinza kweMichiza
I-alkali-resistant fiberglass(umzekelo, i-AR-glass): Iintsinga ezifakwe phezulu zihlala zizinzile kwiindawo eziphezulu ze-alkali, zithintela ukuthotywa.
Ukomelezwa kwe-Interface: I-fiber-matrix bonding eyomeleleyo inciphisa iziphene kwi-ITZ, ukunciphisa umngcipheko wokhukuliseko lwasekhaya.

(3) Ukuchasana neeNdidi eziKhethekileyo zokukhukuliseka
Ukunganyangeki kwe-ion ye-chloride: Ukwakhiwa okuncitshisiweyo kokuqhekeka kunciphisa i-Cl⁻ukungena, ukulibazisa ukubola kwentsimbi.
Ukumelana nokuhlaselwa kwesulfate: Ukukhula okucinezelweyo kunciphisa umonakalo ovela kwicrystallization yesulfate kunye nokwandiswa.
Ukunyibilika komkhenkce: Ukuguquguquka kwefayibha kutsala uxinzelelo ekubunjweni komkhenkce, kuncitshiswe ukuchitheka komhlaba.

4. Imiba ephambili enempembelelo

I-Fiber dosage: Uluhlu oluchanekileyo luyi-0.5% -2% (ngomthamo); iifiber ezigqithisileyo zibangela ukudityaniswa kunye nokuncipha kokuqina.
Ubude beFayibha kunye nokusabalalisa: Iifiber ezinde (12-24 mm) ziphucula ukuqina kodwa zifuna ukusabalalisa okufanayo.
Umgangatho weeaggregates ezisetyenzisiweyo: Ukufunxwa kwamanzi aphezulu okanye isiqulatho sodaka olushiyekileyo lwenza buthathaka ukudityaniswa kwefayibha-matrix.

5. Iziphumo zoPhando kunye neZiphetho eziSebenzayo

Iziphumo ezilungileyo: Uninzi lwezifundo zibonisa ukuba kufanelekilei-fiberglassukongeza kuphucula kakhulu ukunganyanzeki, ukuxhathisa kwekloride, kunye nokumelana ne-sulfate. Ngokomzekelo, i-1% ye-fiberglass inokunciphisa i-chloride diffusion coefficients nge-20% -30%.
Ukusebenza kwexesha elide: Ukuqina kweefiber kwiindawo ze-alkaline kufuna ingqalelo. Iingubo ezimelana nealkali okanye imicu exutyiweyo (umzekelo, enepolypropylene) iphucula ubomi obude.
Unyino: Iiaggregates ezisetyenzisiweyo ezikumgangatho ophantsi (umzekelo, iporosity ephezulu, ubumdaka) zinokuthoba izibonelelo zefiber.

6. Iingcebiso ngezicelo

Iimeko ezifanelekileyo: Imo engqongileyo yaselwandle, imihlaba enetyuwa, okanye izakhiwo ezifuna ukomelela okuphezulu okurisayikilishekayo ikhonkrithi.
Ukulungelelaniswa komxube: Uvavanyo lwedosi yefayibha, ireyisayikilishwe kwakhona yokubuyisela iaggregate, kunye nonxulumano kunye nezongezo (umz., umsi wesilica).
Ulawulo lomgangatho: Qinisekisa ukusasazeka kwefayibha efanayo ukuphepha ukuhlangana ngexesha lokuxuba.

Isishwankathelo

I-Fiberglass yonyusa ukuxhathisa kokhukuliseko lwekhonkrithi esetyenzisiweyo ngokutsha ngokuqina komzimba kunye nokuzinza kweekhemikhali. Ukusebenza kwayo kuxhomekeke kudidi lwefayibha, idosi, kunye nomgangatho odityanisiweyo owenziwe ngokutsha. Uphando lwexesha elizayo kufuneka lugxininise ekuzinzeni kwexesha elide kunye neendlela zokuvelisa iindleko ezisebenzayo ukuququzelela izicelo zobunjineli ezinkulu.
