About Foam Concrete

Foam concrete, also called cellular concrete, is typically made of water, cement and foam. This mixture may also include aggregates or chemicals added to change its physical properties. It is a lightweight material with low density and limited strength in most applications.It is typically a self-levelling and compacting material that is more resistant to cracking and shrinkage than standard 

concrete mixes.

Strength

The strength and durability of foam concrete varies depending on the components mixed into it. For example, foam concrete made with sand is stronger and has a higher density than foam concrete made with just concrete and foam. Some foam concrete mixes include Portland cement that is mixed with the cement and foam by itself or mixed with pulverized fly ash. It may also include limestone. Each of these mixtures makes a cement product ideal for different applications, but typically all foam concrete products become more resistant when compressed and aren’t vulnerable to liquefication or settlement once hardened. 

Advantages of Foam concrete block machine intruduction 

* Lightweight:
Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water.
* Fireproof:
Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
* Soundinsulation:
It has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
* Insulation:
The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
*  Permeability:
Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do.
*  Anti-seismic:
The same building structure, improve the two seismic than the brick level.
*  Green:
Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
*  Durability:
Material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable after ten years.
*  Economies:
An integrated lower cost than using more than 5% of solid clay bricks.

Uses

Foam concrete made with cement and foam only is typically used in roofs and floors as an insulating material. Its low density makes it unsuitable for structural applications but it may be used to fill hollow blocks and voids between bricks and to fill unused culverts and underground voids such as old pipes. Foam concrete made with sand, cement and foam is denser, making it ideal for applications that require a structurally sound material such as when making precast blocks, for insulation and sound- proofing in residential and commercial buildings, foundations and for concrete slab work. Foam concrete may also be used for filling arches in bridges and viaducts, soil replacement and stabilization, and for road foundations.

 

 

How to Make Foam Concrete

 

 

Things You'll Need 

Machines: Concrete mixer     Foam generator      Pump        Formwork or molds   

Materials: Fine sand              Cement                    Water       Chemical foaming agent  etc.

 

Instruction 

 

1.Decide how much concrete foam you need. For a volume of 0.5 cubic meters, you will need: 20

kilograms cement, 200 kilograms dry sand, 100 kilograms water and foam generated at the

correct density depending on your needs.

 

2.Make the foam. Use the foam generator to make stable foam from the chemical foaming agent. 

In general, 500liters of foam will make 1 cubic meter of foamed concrete. Foam generators use anair compressor to generate the foam. Portafoam is an example of smaller foam generating equipment.

 

3.Mix the dry ingredients. Mix thoroughly and add the water in small amounts until sand, cement, and water are well mixed.

 

4. Add the foam to the mortar. Make sure the foam and mortar and well mixed.

 

5.Check the density of the product while wet. The density of dry concrete will be less, so make sure you are calculating based on wet density for your specific needs. For example, density of 600 to 

900 kilograms per cubic meter (38 to 56 lbs per cubic foot) is best for false ceiling and thermal insulation. See the Foam Concrete Physical Characteristics link below for more density recommendations.
