Foamed concrete, also called foamed cement, is to prepare foam from an aqueous solution of a foaming agent, and then add the foam to a slurry made of cement-based cementitious materials, aggregates, admixtures, admixtures, and water. Lightweight porous concrete products made by mixing, pouring and natural curing.  
Features and advantages of LEADCRETE portable foam concrete machine:
1.The portable foam concrete machine has compressive strength; although traditional chemical thermal insulation materials can achieve the thermal insulation effect, their compressive strength performance cannot meet the requirements. Lightweight foamed cement can solve this problem. It is a traditional thermal insulation material replacement of.
2. It has good light weight; its density can reach 200~1600kg/m2, which reduces the weight of the building.
3. Good sound insulation; the sound insulation of lightweight foamed cement is 5-8 times that of ordinary cement, which solves the sound insulation problem of living spaces. 4. Good high temperature resistance; the applicable temperature of foamed cement can reach above 250 ~ 300°C, while the chemical reaction of benzene board will occur above 75°C.
5. Improve the stability and life of the insulation layer; the foamed cement insulation layer has a high degree of stability, ensuring that the indoor floor is flat and not cracked. Its life is 5-10 times that of benzene board and more than 5 times that of perlite particles. 
6. Good environmental performance; all additives of foamed cement are plant protein fiber and animal protein, which is harmless, while chemical insulation materials such as benzene board and perlite particles can produce harmful and toxic gases at high temperatures.
7. Good thermal insulation; the thermal conductivity is 0.08w/m.k, which is 20-30 times that of ordinary cement. 8. It has good compressive strength; when the density is 350kg/m, the compressive strength is 6kg/cm3 for 7 days and 9kg/cm2 for 28 days.
9. Simple construction; foamed cement is a fluid liquid transported by mechanical high pressure, construction saves manpower and material resources, and the surface is smooth and smooth after solidification. 10. Good moisture resistance; there will be no condensation around the warm water pipe during heating, and no cracks between the layers.
11. Good combination; the material used in foamed cement is cement, and the combination with the upper and lower layers is very good, and it will not form ground hollow and collapse.
12. The construction speed is fast; each shift can construct 3000~4000 square meters, saving construction time.
13. Good integrity; no gaps and discontinuities in one-time casting, and can be completely combined with the cast-in-place slab and mortar layer to form a whole.
14. It has the effect of impermeability; due to the porosity and integrity of foamed cement, it is more than 6 times stronger than that of ordinary floor slabs.
15. It has fire resistance; foamed cement is an inorganic material (cement) and will not burn.
