Precisely what is a Cement Foaming Agent?
Concrete/cement foaming agent indicates an admixture that can lessen the surface stress of liquid and generate a considerable amount of uniform and secure foam, which can be utilized to produce foam concrete.
The foaming agent is actually a substance that can make its aqueous solution develop a massive level of foam when mechanical force is introduced right into the air. This type of material is actually a surfactant or surface-active material. The essence of the Cement foaming agent is its surface-active effect. Without surface activity, foaming cannot occur, and it cannot turn into a foaming agent. Surface activity is definitely the core of foaming.
The function of cement foaming agent
The primary function of a cement foaming agent would be to promote the foaming of cement paste to create lightweight concrete. Cement foaming agents can produce bubbles through chemical reactions, causing the cement slurry to have a lot of pores during the construction process, thereby lowering the density of concrete and which makes it lightweight, with thermal insulation, heat insulation, sound absorption, along with other excellent properties.
Cement foaming agents could also enhance the mechanical properties of concrete, enhance its compressive strength and tensile strength, and improve its durability and frost resistance. Furthermore, cement foaming agents could also enhance the fluidity and plasticity of concrete, making it simpler to construct and shape.
12 features and advantages of foaming agent
- It has compressive strength and anti-aging properties: Although traditional chemical insulation materials can achieve thermal insulation effects, their compressive strength and anti-aging properties have not been able to meet the wants. Lightweight foamed cement can totally solve this issue. , a replacement for traditional insulation materials
- It really is lightweight: its density can reach 200-1600kg/m3, which effectively decreases the load in the building.
- Good high-temperature resistance: The applicable temperature of foamed cement can reach above 250-300C, whilst the benzene board will soften and undergo chemical reactions above 75C.
- Enhance the stability and life in the insulation layer: The foamed cement thermal layer features a high degree of stability and anti-aging properties, effectively ensuring that the indoor floor is flat and not cracked. Its lifespan is 5.10 times that relating to the benzene board. It is made from perlite particles. A lot more than five times
- Great thermal insulation: The thermal conductivity is .08w/mk, which can be 20-30 times that relating to ordinary cement.
- It has good compressive strength: if the density is 350kg/m3, the compressive strength is 6kg/cm2 in 7 days and 9kg/cm2 in 28 days.
- Good moisture resistance: There will be no condensation round the warm water pipes during heating, and there will be no splitting between the layers.
- Good bonding: The material found in foamed cement is cement, that has an exceptional bond using the lower and upper layers and will not cause hollowing or collapse in the ground.
- Fast construction speed: each shift can construct 3000-4000 square meters, saving the construction period
- Good integrity: One-time pouring has no gaps and interruptions and can be combined entirely using the cast-in-place floor slab and mortar layer to create a whole.
- It has an anti-permeability effect: As a result of porous and integral nature of foamed cement, the anti-permeability is a lot more than six times stronger compared to ordinary floor slabs.
- Fireproof: Foamed cement is an inorganic material (cement) that fails to burn and for that reason has good fire resistance. When applied to buildings, it may enhance the fireproof performance in the building.
What are the types of cement foaming agents?
Plant-based cement foaming agent
It utilizes imported high-grade natural plant polymer products as basic materials and is also generated via a selection of complicated chain reactions. The product is actually a pure and clear oily liquid having a light yellow color. It is really not responsive to difficult water, non-toxic, odor-free, and sediment-free. The PH worth is near neutral, non-corrosive to cement and steel, and fails to contaminate the setting. The frothing representative is storage-resistant, tough to degrade, has exceptional frothing performance, rich foam, and modest foam stability. Utilizing this frothing agent to create foamed cement provides the attributes of reduced usage, affordability, stability, and high quality. Each barrel of frothing agent (200kg) can generate 500 m2 of foamed cement, so it will be commonly found in floor home heating jobs. In roofing insulation projects, building prices could be considerably minimized.
Animal-based cement foaming agent
It uses selected animal (cow, sheep) keratin since the primary raw material and is also made through a number of hydrolysis reactions, heating and dissolving, dilution, filtration, and high-temperature shrinkage. It really is produced using imported advanced equipment and the latest manufacturing technology. Strict quality management is implemented during the production process. The product is actually a deep brown viscous liquid with low impurity content, light irritating odor, uniform quality, sound quality consistency, outstanding foaming, and excellent foam stability; it really is a new generation of animal-based cement foaming agents. As a result of high surface strength in the foam made by this foaming agent, the foam is very stable. The bubbles in the foamed cement created using it will be in a closed state independent of every other, and there is absolutely no link between the bubbles. The permeability resistance in the foamed cement products is extremely high. On the same density, compared with foamed cement created using plant-based foaming agents, it offers better sealing and heat preservation properties and better strength.
The uses of cement foaming agent
- Construction industry
Cement foaming agents are commonly used inside the construction area and therefore are mainly used to produce lightweight concrete, thermal insulation materials, thermal insulation materials, sound-absorbing materials, etc. Lightweight wet-condensation materials have the benefits of lightweight thermal insulation, sound absorption, etc. They may be commonly used in building walls, floors, roofs, partitions, along with other components. Thermal insulation materials can be used building insulation, heat insulation, fire protection, etc. Sound-absorbing materials can be used building sound insulation and noise reduction.
- Road industry
Cement foaming agents can also be found in the broad area and therefore are mainly used to produce lightweight pavement materials, sound insulation materials, waterproof materials, etc. Lightweight pavement materials have the benefits of light, wear resistance, and anti-aging and can reduce road noise and vibration. Sound insulation materials can be used road sound insulation, noise reduction, etc. Waterproof materials can be used road waterproofing and anti-seepage.
- Bridge industry
Cement foaming agents can also be found in the bridge area, mainly used to produce lightweight bridge decks, sound insulation materials, waterproof materials, etc. Lightweight bridge deck has the benefits of being lightweight, high strength, and good durability, which could detect the weight in the bridge and extend the service life in the bridge. Sound insulation and waterproof materials can be used bridge sound insulation, waterproofing, etc.
