Cellular foam concrete manufacturing machine
Foam concrete has been used in developed countries for more than 50 years. The compressive strength is not as great as ordinary concrete, but it weathers just as well. Among its advantages are less need for structural steel reinforcement, smaller foundation requirements, better fire resistance and most importantly, the fact that it can serve as an insulation material.
The foam is produced with the help of a foam generator by using foaming agent. The air content is typically between 40 to 80 percent of the total volume. The bubbles vary in size from around 0.1 to 1.5 mm in diameter. Foamed concrete differentiates from gas or aerated concrete, where the bubbles are chemically formed through the reaction of aluminium powder with calcium hydro oxide and other alkalies released by cement hydration and air entrained concrete, which has a much lower volume of entrained air is used in concrete for durability. We can also used cellular foam concrete manufacturing machine, can make the walls, make bricks and proof insulation. Cellular foam concrete manufacturing machine has become widely used in the construction industry, mostly for cast-in-situ applications in roof slopes, floor levelling and insulating layers of wall constructions, as well as for any kind of void filling (mines, tunnels, road basements, ground stabilization, land reclamation and others), owing to its free-flowing properties, excellent heat-insulating characteristics, low density and affordable strength values.
It is a bubble-like insulation material, which is characterized by the formation of closed foam holes in the concrete to make the concrete lighter and insulated. The foam holes in the foam concrete block are not connected, so the foam concrete block has good heat preservation performance, low water permeability and good sound insulation effect. The production of foam concrete block, the foaming agent is physically foamed by the cellular foam concrete manufacturing machine, and then the bubbles are added to the cement. Mixed in the slurry, the foam concrete block is cured at room temperature or dry heat.
Foam concrete block made by cellular foam concrete manufacturing machine has many unique performances:
1. Lightweight and high strength, reduce building load: dry density 320-1200kg/m3, which is 1/5-1/8 of ordinary concrete or block.
2. Good thermal insulation, sound insulation performance: its thermal conductivity of 0.06-0.16w / m.k, 24cm thick wall insulation is 58dB, to meet the building exterior wall, household wall insulation, sound insulation requirements.
3. Good compression performance: compressive strength is greater than 0.5Mpa, the highest strength can reach more than 10.5Mpa.
4. Good shock resistance: Because the foam concrete block is a porous material, it has a low modulus of elasticity, so that it has good absorption and dispersion effect on the shock load, and the foam concrete block is light in weight, effectively reducing the building.
5. No cracking, long service life: foam concrete block will not appear cracking and empty drum phenomenon, no need to brush the interface agent when used, anti-aging performance is outstanding, long service life.
6. Good water resistance: the water absorption of foam concrete material is less than 10%, which is obviously different from other wall self-insulation materials.
