Liphello tsa Foam Concrete Density ho Mechanical Properties ea Foam Concrete

Ho entsoe merero e fapaneng ea lipatlisiso ho ithuta thepa ea mochini oa konkreite ea foam. Ba tšoaile microstructure ea konkreite ea foam le ho ntlafatsa thepa ea thepa ena. Boithuto bo latelang bo batlisisa litlamorao tsa letsoalo la mohlala ho thepa ea mochini ea konkreite ea foam.

Konkreite ea foam ke thepa e bobebe e nang le metsi a mangata le thepa ea ho kenya mocheso. E boetse e na le tekanyo e phahameng ea matla ho boima ba 'mele, ho kenella ka tlase, le khanyetso e ntle ea mollo. Ke thepa e tlaase-tlaase, boima bo ka tlase ho liponto tse likete tse peli ka cubic foot. Haholo-holo e entsoe ka lehlabathe, samente, metsi, le fofa molora. Boima ba konkreite ea foam bo itšetlehile ka bongata ba lisebelisoa tsena tsa motheo le puso ea ho kopanya.

Litšobotsi tsa 'mele tsa M-2, motsoako o nang le molora oa fofa le samente, li bonts'oa ho Tafole 8. Matla, matla a hatellang, le matla a matla a M-2 a amanang le sekhahla sa khatello. Matla a ho qetela a khatello le matla a ho monya matla a ile a eketseha ka bongata.

Tšusumetso e matla ea M-2 e bontšitse kamano e matla le boleng ba khatello ea maikutlo. Boleng ba khatello ea maikutlo bo ile ba eketseha ka sekhahla sa khatello e ntseng e eketseha le lebelo la tšusumetso. Matla a matla a ho hatella a ne a amana le sekhahla sa khatello ha 10-100 s-1. Kamano pakeng tsa sekhahla sa khatello le matla a matla a ho hatella a ne a tšoana le a konkreite ea setso.

Litšobotsi tsa sebopeho sa konkreite ea foam li ile tsa batlisisoa ho sebelisoa microscope ea elektronike. Litšoantšo li fumanoe ho sebelisoa Quanta 250 FEG (Applied Precision Ltd., Bratislava, Slovakia) e sebetsang ka mokhoa oa vacuum e tlase. Mokhoa ona o fane ka litšoantšo tse qaqileng tsa mehlala e seng ea conductive ntle le tlhokahalo ea ho roala sputter.
