Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
ikhonkrithi yogwebu Ikhonkrithi ekhaphukhaphu eyenziwe ngokuxuba iiaggregates ezintle, ezenza amagwebu kunye namanzi. Inokuveliswa kunye nendalo okanye i-synthetic i-foaming agents.
Ikhonkrithi ekhanyayo ineenzuzo ezininzi ngaphezu kwekhonkrithi eqhelekileyo, ezifana neendleko eziphantsi, ukwakhiwa ngokukhawuleza, amandla aphezulu kunye nefuthe eliphantsi kokusingqongileyo. Ingasetyenziswa kuluhlu olubanzi lwezicelo ezibandakanya ukugquma, izinto zokwakha, ukuzaliswa kwe-voids kunye ne-grouting.
Iimpawu zayo ziquka umlinganiselo ophezulu wamandla-kuya-ubunzima, ubunzima obulula, ukugcinwa kobushushu, ukugquma kwesandi kunye nokumelana nomhlwa. Inokuveliswa ngeendlela ezahlukeneyo zokuxutywa, kuquka ikalika, igypsum, isamente kunye nothuthu.
Amandla acinezelayo: Amandla oxinzelelo lwe ikhonkrithi yogwebu kuxhomekeke kumlinganiselo wesamente yamanzi, uyilo lokuxuba kunye nohlobo lwe-arhente yogwebu. Inokuba phakathi 1.0 kwaye 15 MPa, kuxhomekeke kubungakanani be-foam kunye nebakala le-samente.
Ukufakwa kwe-thermal: Iimpawu zokufudumala kwe ikhonkrithi yogwebu zikwachatshazelwa bubume bepore kunye nokusabalalisa ubungakanani be-air voids. Umoya uyancipha ngakumbi, ngcono ukugquma.
Ukomisa ukushwabana: ikhonkrithi yogwebus zinokomisa ukuncipha okuncinci kunekhonkrithi eqhelekileyo. Oku kungenxa yokuba i-air voids ixinene ngakumbi kunamasuntswana adibeneyo.
Ukonakala: Ubume beselula ye ikhonkrithi yogwebu inobuxhakaxhaka obukhulu bomhlwa kunesakhiwo seselula sekhonkrithi eqhelekileyo. Ngoko ke lolona khetho lubalaseleyo kulwakhiwo lwangaphandle olukhuselweyo apho umhlwa kuyingxaki.
Ukongeza i-carbon fiber (CF) kwi ikhonkrithi yogwebu kwandisa ukusebenza kwayo koomatshini. Nangona kunjalo, i-CF kufuneka ilungiswe phambi kokuba yongezwe kumxube wekhonkrithi.
