Foam concrete insulation layer construction method:

(1) mark the thickness and slope of heat insulation layer around the construction wall.

(2) use a special mixer to mix new foaming agent, cement (or cement, fly ash and other mixtures), water and other materials into a uniform liquid foam concrete, and then use template pouring to gather to the roof (also can be large equipment from the ground directly pumped to the roof and directly cast), to achieve the corresponding thickness.

(3) the roof insulation layer is done, 2-3 days can not be manned, can not bear the load.

Advantages of foam concrete insulation layer:

1. High heat resistance.Foamed concrete is cement inorganic material, heat resistance can reach more than 500℃, there is no thermal decomposition, so the service life is longer, not heat preservation failure.

2. green environmental protection, non-toxic harmless.Foamed concrete does not contain any toxic ingredients, foaming agents and various additives are not volatile harmful substances, which is beneficial to indoor environment.

3. Strong carrying capacity.The compressive strength of polystyrene foamed plastic, only 0.02 ~ 0.03MPa, and 200 ~ 300 nanostructural structural strength of foamed concrete is 0.6 ~ 0.8MPa, the compressive performance is better.

4. Low use cost.Foamed cement (foamed concrete) has obvious economic advantages compared with polystyrene foamed plastics.

5. No joints, reducing the heat loss caused by joints.And polystyrene foam plastic board is laid one by one, with many joints, easy to form a cold bridge or hot bridge.
