Foam Concrete Boima ba Boima le Matla a Flexural

Phokotso ea Boima ka Konkreite ea Foam

E 'ngoe ea melemo e ka sehloohong ea konkreite ea foam ke ho fokotsa boima ba eona (ho fihlela 80%) ha e bapisoa le konkreite e tloaelehileng. Ho fapana le konkreite e tloaelehileng, li-bubble tsa moea li ajoa ka ho lekana ho pholletsa le 'mele oa konkreite ea foam le boholo ba tsona bo fapana ho tloha 0.1 ho 1 mm.

Boima ba konkreite ea foam bo ipapisitse le palo ea mokelikeli oa foaming mme bo fapana lipakeng 400 le 1600 kg/m3. E loketse bakeng sa sebopeho, karohano, ho kenya letsoho le ho tlatsa lits'ebetso tse nang le acoustic / thermal insulation e ntle haholo, khanyetso e phahameng ea mollo, litšenyehelo tse tlase tsa thepa e tala, ho pompa ha bonolo 'me qetellong ha ho na compaction, ho thothomela kapa boemo bo phahameng [1].

Flexural Matla

Matla a hatellang a konkreite ea foam a itšetlehile ka mofuta oa sesebelisoa sa foaming se sebelisitsoeng le puso ea hydration. Holim'a moo, elasticity modulus ea konkreite ea foam e boetse e itšetlehile ka bongata le lintlha tse ling tse ngata.

Li-foaming agents le li-surfactants li tlameha ho hlapolloa ka metsi pele li ferekanngoa ka ho “koae” ho hlahisa foam e tsitsitseng. Katoloso e tloaelehileng bakeng sa foam e omeletseng ea protheine ke 20 makhetlo a mokedikedi wa sephahafatsi.

Lisebelisoa tse fokotsang metsi le li-plasticiser ha li kopane hantle le li-foaming agents. Ho qoba sena, superplasticizer hangata e sebelisoa ka metsoako ea konkreite e foamed.

Ho bohlokoa ho etsa bonnete ba hore moea o kentsoeng o lula o tsitsitse, nyane, li-bubble tse ts'oanang tse lulang li tiile ebile li arohane 'me ha li eketse ho kenella ha pente ea samente lipakeng tsa li-voids.. Sena se finyelloa ka ho etsa bonnete ba hore mokelikeli o foaming o hlapollotsoe ka tlaase 3% – 5% karo-karolelano le metsi pele e ferekanngoa ka ho “koae”. Ho ba teng ha li-air voids ha ho fokotse modulus ea elasticity mme konkreite e lumellana le litlhoko tsohle tsa sebopeho sa mojaro..
