Foamed Concrete for Disaster-Resilient Hospitals

What exactly is a Cement Foaming Agent?

Concrete/cement foaming agent indicates an admixture that can lessen the surface stress of liquid and generate a considerable quantity of uniform and secure foam, which can be employed to produce foam concrete.
The foaming agent is actually a substance that can make its aqueous solution create a massive quantity 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 a Cement foaming agent is its surface-active effect. Without surface activity, foaming cannot occur, plus it cannot become a foaming agent. Surface activity is definitely the core of foaming.

The function of cement foaming agent

The key function of a cement foaming agent is always to promote the foaming of cement paste to make lightweight concrete. Cement foaming agents can produce bubbles through chemical reactions, causing the cement slurry to have a large number of pores through the construction process, thereby lowering the density of concrete and which makes it lightweight, with thermal insulation, heat insulation, sound absorption, as well as other excellent properties.
Cement foaming agents can also enhance the mechanical properties of concrete, enhance its compressive strength and tensile strength, and improve its durability and frost resistance. In addition, cement foaming agents can also enhance the fluidity and plasticity of concrete, making it easier to create and shape.

12 features and advantages of foaming agent

  1. It provides 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 alternative to traditional insulation materials
  2. It is actually lightweight: its density can reach 200-1600kg/m3, which effectively decreases the load from the building.
  3. Good high-temperature resistance: The applicable temperature of foamed cement can reach above 250-300C, as the benzene board will soften and undergo chemical reactions above 75C.
  4. Improve the stability and life from the insulation layer: The foamed cement thermal layer features a high amount of stability and anti-aging properties, effectively making sure the indoor floor is flat and never cracked. Its lifespan is 5.10 times those of the benzene board. It consists of perlite particles. Greater than 5 times
  5. Great thermal insulation: The thermal conductivity is .08w/mk, which can be 20-30 times those of ordinary cement.
  6. It provides good compressive strength: when the density is 350kg/m3, the compressive strength is 6kg/cm2 in 7 days and 9kg/cm2 in 28 days.
  7. Good moisture resistance: You will see no condensation round the warm water pipes during heating, and you will see no splitting between the layers.
  8. Good bonding: The material used in foamed cement is cement, that has an outstanding bond with the lower and upper layers and will not cause hollowing or collapse from the ground.
  9. Fast construction speed: each shift can construct 3000-4000 square meters, saving the construction period
  10. Good integrity: One-time pouring has no gaps and interruptions and will be combined entirely with the cast-in-place floor slab and mortar layer to make a whole.
  11. It provides an anti-permeability effect: Due to the porous and integral nature of foamed cement, the anti-permeability is more than six times stronger compared to ordinary floor slabs.
  12. Fireproof: Foamed cement is an inorganic material (cement) that will not burn and for that reason has good fire resistance. When used on buildings, it could enhance the fireproof performance from 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 an accumulation of complicated chain reactions. The product is actually a pure and clear oily liquid using a light yellow color. It is not sensitive to difficult water, non-toxic, odor-free, and sediment-free. The PH worth is near to neutral, non-corrosive to cement and steel, and will not contaminate the setting. The frothing representative is storage-resistant, difficult to degrade, has exceptional frothing performance, rich foam, and modest foam stability. Utilizing this frothing agent to create foamed cement has the highlights of reduced usage, affordability, stability, and high quality. Each barrel of frothing agent (200kg) can generate 500 m2 of foamed cement, so it is commonly employed in floor home heating jobs. In roofing insulation projects, building prices may 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 series of hydrolysis reactions, heating and dissolving, dilution, filtration, and high-temperature shrinkage. It is actually produced using imported advanced equipment and the latest manufacturing technology. Strict quality management is implemented through 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 is a new generation of animal-based cement foaming agents. Due to the high surface strength from the foam created by this foaming agent, the foam is very stable. The bubbles from the foamed cement created using it have been in a closed state independent of each other, and there is not any link between the bubbles. The permeability resistance from the foamed cement products is very high. At the same density, in contrast to foamed cement created using plant-based foaming agents, it has better sealing and also heat preservation properties and better strength.

The uses of cement foaming agent

  1. Construction area

Cement foaming agents are popular in 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 popular in building walls, floors, roofs, partitions, as well as other components. Thermal insulation materials can be used for building insulation, heat insulation, fire protection, etc. Sound-absorbing materials can be used for building sound insulation and noise reduction.

  1. Road area

Cement foaming agents are also used 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 will reduce road noise and vibration. Sound insulation materials can be used for road sound insulation, noise reduction, etc. Waterproof materials can be used for road waterproofing and anti-seepage.

  1. Bridge area

Cement foaming agents are also used 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 may detect the weight from the bridge and extend the service life from the bridge. Sound insulation and waterproof materials can be used for bridge sound insulation, waterproofing, etc.
