Iimfuno zeConcrete Admixture Silica Fume kwi-High Abrasion Resistance Concrete kuMgangatho woShishino

Yintoni

Umsi we-silika ngumgubo omkhulu kakhulu osetyenziswa njengomxube kwikhonkrithi. Isuka ekwenziweni kwentsimbi yesilicon okanye iialloys zeferrosilicon. Esi sixhobo sininzi sakhiwe kwi-silica ye-amorphous. Xa yongezwa kwikhonkrithi, igcwalisa izithuba ezincinci phakathi kwamaqhekeza ekhonkrithi. Oku kwenza ukuba ikhonkrithi ixinene kwaye yomelele.

Kutheni Uyisebenzisa kuMgangatho woShishino

Imigangatho yemizi-mveliso ijongene neyure engxamisekileyo, ukunxiba okuhambelanayo, kunye nempembelelo koomatshini. Ikhonkrithi yesiqhelo inokwahlula okanye isebenzise ngokukhawuleza phantsi kwezi ngxaki. Kubandakanywa umsi wesilika kwandisa kakhulu ukuxhathisa kwe-abrasion. Umphezulu osisiphumo uhlala ugudile kwaye ungonakali ixesha elide. Kananjalo kunciphisa ukucoca kunye nokukala, eyona miba iphambili kumzi-mveliso kunye neendawo zokugcina.

Iingenelo eziSebenza kakuhle kwiMfihlo

Ikhonkrithi ene-silica fume ibonisa amandla amakhulu oxinzelelo kunye ne-flexural stamina. Ukuvuza kwayo okuncitshisiweyo kwisakhiwo kuthintela amanzi, iikhemikhali, kunye neekloridi ekungeneni. Oku kunceda ukuphepha ukuwohloka kokuqiniswa kwentsimbi ngezantsi. Umxube uzuza unxibelelwano olungcono kakhulu, oku kuthetha ukopha okuncinci kunye nokwahlulwa kulo lonke ukubekwa. Ezi mpawu zizisa ukuhambelana kakhulu, ukugqiba komgangatho ixesha elide.

Umthamo ocetyisiweyo kunye nokuPhathwa

Sebenzisa umsi we-silica 5% ukuya 10% ngobunzima besamente. Soloko uyixube ngokupheleleyo nezinye izithako ezomileyo phambi kokuba udibanise namanzi. Kuba umsi wesilica uthatha amanzi amaninzi, unokufuna isinciphisi samanzi soluhlu oluphezulu ukugcina umxube usebenza. Gcina umgubo kwindawo eyomileyo ngokupheleleyo.

Iikhrayitheriya kunye nokuhambelana

Le nto idibana ne-ASTM C1240 kunye ne-EN 13263 iimfuno zomsi wesilica kwikhonkrithi. Ilungele ukusetyenziswa kwiiprojekthi ezihambelana ne-ACI 302.1 Izikhokelo ze-R kwi-industrial flooring slabs. Vavanya rhoqo iibhetshi zovavanyo ngaphambi kwesicelo esipheleleyo sokuqinisekisa ukusebenza phantsi kweemeko ezithile zewebhusayithi yakho.

Ukusetyenziswa kweConcrete Admixture Silica Fume ye-High Abrasion Resistance Concrete kwiMigangatho yoShishino

Yandisa ubomi obude boMgangatho ngeSilica Fume

Kutheni imigangatho yoShishino ifuna ukuqina kweBhonasi

Imigangatho yemizi-mveliso ijongene neyure engxamisekileyo yonke imihla. Iiforklift, oomatshini, kunye nokushukuma rhoqo sebenzisa phantsi ikhonkrithi eqhelekileyo ngokukhawuleza. Imixube yesiqhelo iyaqhekeka, itshiphu, okanye ukuwohloka phantsi kolu xinzelelo kunye nexhala. Kulapho isenzo se-silica fume singena khona.

I-silica fume ngumgubo ocolekileyo kakhulu oqukwe kwimixube yekhonkrithi. Izalisa izithuba ezincinci phakathi kweebhithi zekhonkrithi. Oku kwenza ikhonkrithi ixinene kakhulu. Umxube oxineneyo ucebisa iindawo ezibuthathaka ezincinci. Amanqaku ambalwa abuthathaka abangela ukuxhathisa okungcono kakhulu kwi-abrasion.

Kanye indlela iSilica Fume esebenza ngayo

Xa zidityaniswe ngqo kwikhonkrithi, umsi we-silica uphendula nge-calcium hydroxide– imveliso yendalo ye-cement hydration. Le mpendulo idala imveliso eyongezelelweyo yokubopha ngaphakathi kwekhonkrithi. Isiphumo? A umngeni ngakumbi, umphezulu oqinileyo othatha ukugaya, ukukrwela, kunye nefuthe.

Umgangatho ophathwe nge-silica fume uveza uthuli oluncinci ngexesha. Kananjalo ziyamelana nokungena kwamanzi kunye neekhemikhali ngcono kakhulu. Oku kubalulekile kumaziko okuvelisa, iindawo zokugcina, kunye nokupakisha iidokhi apho ukuchitheka kunye nobumanzi bukho.

Kubandakanya nje 5% ukuya 10% Umsi we-silica ngobunzima besamente unokuphinda kabini ukuxhathisa ukukrazuka. Iikontraka zibona iinkonzo zokulungisa ezincinci kunye nobomi obude. Amaxabiso olondolozo aye ehla kuba indawo engaphezulu ihleli injalo ixesha elide.

Intsebenzo yeReal-World

Izityalo ezijongene nezinto ezininzi– njengengqolowa, amalahle, okanye ii-aggregates– inzuzo kakhulu. Imigangatho yabo ithatha isohlwayo esiqhubekayo ekutsaleni, ukuwisa, kunye namaqashiso aqengqelekayo. I-silica umsi ikhonkrithi ime apho amaqhekeza aqhelekileyo ngokuqinisekileyo aya kuyeka ukusebenza kwiinyanga ezimbalwa.

Umxube ngokunjalo ufumana amandla kwangoko ngokukhawuleza. Oku kuvumela abasebenzi ukuba bavule imigangatho ukuze kulayishwe itrafiki ngokukhawuleza. Iiprojekthi zihlala kwishedyuli ngaphandle kokuncama umgangatho ophezulu.

Ukusetyenziswa komsi we-silica kufuna ukudibanisa ngononophelo kunye nokuphiliswa. Kodwa i-payback icacile: umgangatho ohlala iminyaka emininzi phantsi kweemeko ezirhabaxa. Kuyo nayiphi na imeko yorhwebo apho ukuqina kungaxoxiswana, Umsi we-silica ayisiyonto nje inketho– lutyalo-mali olulumkileyo.
