Are you interested in setting up a business where you can insulate existing houses with foam concrete and making in situi panels? We have a foam concrete machine for making in situi panels fo you.
Foamed concrete, also known as foamed concrete, is formed by foaming and adding a blowing agent to a slurry made of a cement material, an admixture, a modifier, water, etc., which is mixed and cast. , naturally solidified. A new type of lightweight insulation material containing a large number of closed cells. Foam concrete made by foam concrete machine is an excellent building material, used to make CLC blocks, lightweight wall panels, wall casting, void filling, roof heating, floor heating,etc.
Why do so many people choose to use foam concrete wall panels as houses? Because foam concrete wall panels have many outstanding advantages:
1. Light weight: dry bulk density of 300 kg / cubic meter -3,500 kg / m ^ 3, 1 / 8-1 / 2, as light as ordinary concrete, small construction, good seismic performance.
2. High compressive strength: The compressive strength ranges from 0.6 MPa to 25 MPa, which is four times that of conventional aerated concrete.
3. Insulation: low thermal conductivity, good thermal insulation and good thermal insulation.
4. Impermeability: low water absorption and high impermeability.
5. Energy saving: permanent energy saving measures, reaching 65% of the national building energy efficiency regulations.
6. Labor saving and time saving: the wall surface is smooth and smooth after solidification. The procedure for interior wall plastering can be omitted, direct roughening, paint filling, coating and wall tiles are possible.
7. Tight bonding: The combination of cast-in-place and foundation structure ensures firmness, rather than creating common quality defects such as hollows, flaking, unevenness, collapse, cracks, etc., because the main raw material of LP foam concrete is cement.
8. Good overallity: One-time casting can be well connected to casting cast-in-place slabs, mortar beds, columns and beam bottoms, without cracks and interruptions.
9. High durability: LP foam concrete cast-in-place wall guarantees the same warranty as the main structure.
10. Low comprehensive cost: Compared with clay bricks, non-baked bricks and steam-free aerated concrete blocks, LP foam concrete has the advantages of low comprehensive cost and high progress rate.
Foamed concrete has good performance in wall casting. Foamed concrete is more advanced than foamed polystyrene.
A disadvantage of styrofoam is that the heat resistant temperature is low and differentiation begins at 74 °C. As the temperature continues to rise, it will melt and shrink. The temperature of the floor heating hot water pipe is not constant, sometimes exceeding 74 ° C, which will form the thermal differentiation of the polystyrene foam, which will invalidate the insulation. The cast-in-place foam concrete is cement inorganic material, the heat resistance can reach above 500 °C, no thermal differentiation, long service life and good heat preservation effect.
Green, non-toxic and harmless. The cast-in-place foam concrete does not contain toxic components, and the foaming agent and various additives do not contain volatile harmful substances, which is beneficial to the indoor environment. Styrofoam releases styrene toxic gases due to thermal differentiation. Therefore, the use of foam concrete is more environmentally friendly than the use of polystyrene foam.
The strength is better than that of polystyrene foam. The compressive strength of polystyrene foam is only 0.02-0.03 MPa, and the compressive strength of foam concrete is 200-300 kg / m3, which is 0.6-0.8 MPa, and the pressure resistance is better.
Reduce the cost of use. The cost is 30% to 40% lower than that of polystyrene foam and has obvious economic advantages.
Construction speed is fast. The cast-in-place foam lightweight soil is flat and can be laid flat, and the construction speed is 1/3 faster than that of the polystyrene foam board. Without seams, the heat loss caused by the seam is reduced. The styrofoam panels are laid one after the other and have a number of seams that tend to form a cold bridge or a thermal bridge.
So if you want to make walls or build houses, you can choose foam concrete rather than styrofoam. And our foam concrete machine is specially designed for wall casting, it is a good choice.
