The workability of concrete refers to the ease of construction operation (mixing, transportation, pouring, tamping) of the concrete mixture and the performance of small molding, uniform quality, no segregation, and no bleeding.
Physical foaming refers to mechanical foaming. Air is introduced during full stirring or shearing by machinery, and the sky is wrapped with a surfactant or an aqueous solution of a surface-active substance. In the physical foaming process, to prevent the
The introduction of pores in Foam concrete, on the one hand, gives it lightweight, sound insulation, thermal insulation, high fluidity, and other properties that ordinary concrete does not have. Still, from the perspective of structure and mechanics, it a
Foam concrete is another insulation material after the benzene board. Foaming cement used in-floor heating, general bulk weight 350 ~ 450kg/m3, thermal conductivity 0.087w /m.k, the content not only has the advantages of high compressive strength, low the
Most of the applications in the concrete foam field are solid-liquid phase change materials. During the phase change process, the solid-liquid phase change material will be converted from a solid-state to a liquid state, and it will flow directly in the b
Foam concrete products have the advantages of a lightweight, heat insulation, fire resistance, convenient construction, etc. Due to the large number of small micro-bubbles, the density of lightweight concrete products is small, and the density is often 30
