Foam is one of foam concrete main constituents, and air is brought in the inside of concrete mortar, made by foam It has loose structure disconnected from each other after curing, and obtaining concrete, bulk density is small, and porosity is big, and thermal insulation is good With the premium properties such as frost resistance height.The quality of foam, such as size, shape, stability etc. directly affect foam concrete performance.Cause This foam is the basis to form foam concrete.Foam refers to that insoluble (or slightly soluble) property gas is scattered in the multiphase formed in liquid Dispersion, wherein gas are dispersed phase (discontinuous phases), and liquid is decentralized medium (continuous phase).Foam is gathered by a large amount of bubbles Collection forms, and the liquid for wrapping up gas is referred to as liquid film or vacuolar membrane.
Foam is Unstable Systems thermodynamically, the system being scattered in as gas in liquid, it have than air and The taller free energy of liquid free energy sum, therefore foam can be with time spontaneous breaking, to reduce total free energy of the system. The main reason for causing foam to destroy is the diffusion of gas in foams drain and foam.
