Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
Izongezo zekhonkrithi ezikhaphukhaphu zingasetyenziselwa ukubuyisela iiaggregates zendalo ezixineneyo kwikhonkrithi yesakhiwo. Ezi zongezo zinokunciphisa iindleko zezinto kunye nokuphatha. Banokonyusa i-thermal insulation yekhonkrithi kunye nokuphucula ukumelana nomlilo.
Ikhonkrithi enegwebu yenye yezona zisetyenziswa ngokuqhelekileyo iikhonkrithi ezikhaphukhaphu. Iveliswa ngenkqubo yokuqulunqwa kwangaphambili. I-arhente yogwebu yazisa amaqamza omoya asasazwe ngokungenamkhethe kumxube. Oku kubangela ukuxinana okusezantsi.
Amacandelo aphambili ekhonkrithi enegwebu yi-arhente yogwebu kunye ne-stabilizer. I-arhente yokuzinzisa idla ngokudibaniswa kwi-slurry yebhetshi yekhonkrithi enegwebu.
Ngaphandle kokunciphisa iindleko zezinto eziphathekayo, ezi zongezo zinokuphucula isakhiwo kunye nokusebenza kwekhonkrithi ekhaphukhaphu. Ukusebenzisa ezi zongezo kunokunceda ekunciphiseni iimfuno zetsimbi zeprojekthi.
Uphononongo oluninzi luye lwenziwa ukuphanda amandla acinezelayo eentlobo ngeentlobo zekhonkrithi ekhaphukhaphu. Kuye kwaphawulwa ukuba ukuxinana kwekhonkrithi kuluhlu lwe 350 ukuya 50 kg/m3 zamkelekile.
Nangona kunjalo, ingxinano yayingaphantsi kancinane kunezo zikwimeko yobunzima obuqhelekileyo bekhonkrithi. Ezinye zezifundo ziphande impembelelo ye-nanosilica kuxinaniso lwekhonkrithi enegwebu.
Olunye uphononongo luphande impembelelo yemathiriyeli eyongezelelweyo yesamente ekusebenzeni kwekhonkrithi enogwebu ekhaphukhaphu.. Ababhali bafumanisa ukuba ukufakwa kwezi zithako kunciphise izinga lokuncipha kwekhonkrithi.
Ngaphaya koko, ukusetyenziswa kwe-nanosilica kuphuculwe amandla ekhonkrithi ngokucoca isakhiwo se-pore. Ukwengeza, Ubuninzi bekhonkrithi banda ngokubandakanywa kwe-nanosilica.
