konkreite ea foam ke eng?
Konkreite ea foam ke mofuta oa konkreite e bobebe ebile e le masoba. E ka sebelisoa bakeng sa sebopeho, li-partitioning le li-insulation applications hammoho le ho tlatsa likopo. E ka hlahisoa ka lisebelisoa tse fapaneng mme e na le litšobotsi tse ikhethang tse kenyelletsang ho ba bobebe, matla a fokolang a laoloang, Insulation ea mocheso le ts'ebetso ea li-acoustics.
Phapang ke efe pakeng tsa "fresh" le hardened density?
Thepa e ncha le e thata ea konkreite ea foam e angoa haholo ke sebopeho sa pore, microstructure le karo-karolelano ea samente ea metsi. Sebopeho sa pore se susumetsoa ke mofuta oa kakaretso le litaba tsa li-additives tsa diminerale.
Phello ea FA ho omisa shrinkage
Tšebeliso ea li-aggregate tse nyane (FA) ha ho lokisoa konkreite ea foam e na le phello e mpe ho omisa shrinkage [6,8,11,12]. Keketseho ea ho monya ha metsi liphaseteng tsa FA e eketsa sekhahla sa mouoane 'me boima bo fokotseha. Holim'a moo, kabo ea boholo ba pore ea lehlabathe la FA ka konkreite ea foam e fokotsehile ka lebaka la sebopeho sa eona se se nang letho ha se bapisoa le lehlabathe la tlhaho.
Matla a hatellang ka konkreite ea foam a ka eketsoa ka ho eketsoa ha mosi oa silika ho konkreite, kapa ka quicklime ka konkreite ea foam ea autoclave. Sena se eketsa matla a hatellang a konkreite ea foam, haholo-holo ha e lokiselitsoe ka tekanyo e tsitsitseng ea samente le ho eketseha ha litaba tsa li-additives tsa diminerale.
The permeability, porosity, boholo ba pore le kabo ea pore ea lisebelisoa tse thehiloeng ho konkreite kaofela li amana ka kotloloho le thepa ea bona ea matla. The porosity, permeability le boholo ba pore ea konkreite ea foam le tsona li bohlokoa hobane li susumetsa mochini, Thermal le durability properties of the material.
