Überblick über Schaumbeton

CLC brick making process

In traditional foam concrete production, the cement foaming agent is dissolved. The foam generator is used to mix the foam produced by it into the slurry composed of cementitious materials and admixtures used in concrete. The foam concrete with micropores is obtained after mixing, Gießen, Formen, und Heilung.

Characteristics of foam concrete

Die Schaumbetondichte beträgt ca 500-1200 kg/m3; Wärmeleitfähigkeit ist im Allgemeinen 0.12-0.30 W/(m·k).Die Druckfestigkeit beträgt im Allgemeinen 3-14 MPa, und wird häufig als Dämmschicht für Dächer verwendet, selbsttragende Wände, und Thermorohre. The current ultra-light foam concrete has a very low density and thermal conductivity, and its thermal performance is very excellent, such as a density of 80 kg/m3.The thermal conductivity of foamed concrete is 0.040 W/(m·k); the thermal conductivity of foamed concrete with a density of 100 kg/m3 is 0.043 W/(m·k); the thermal conductivity of foamed concrete with a thickness of 120 kg/m3 is It is 0.047 W/(m·k). Derzeit, in the world, if the material has a low thermal conductivity, it can be called an insulation material. The thermal conductivity of high-efficiency insulation materials must be lower than 0.05 W/(m·k). Ultra-light foam concrete has been used as a high-efficiency thermal insulation material, its performance is entirely comparable to organic thermal insulation materials such as polyurethane and polystyrene, and because of its high flame retardant coefficient, long service life.

Toxic gas has now become a popularized product of building insulation materials and has begun to gradually replace organic insulation materials on the market, becoming the new favorite of the building insulation industry.

Another definition of foam concrete is: Zement verwenden, Beimischungen, usw. as the primary cementing material, add water and foam concrete admixture to prepare a slurry, and then foam through the cement foaming agent, cast, Form, and cure to make A large number of small, independent, lightweight foam concrete with uniformly distributed bubbles.

Foam concrete specification

(1) Classification according to the difference in density

Thermal insulation foam concrete: foam concrete mainly used for thermal insulation. Normalerweise, it is foamed concrete with a bulk density of 400 kg/m3 or less. The ultra-light foam concrete made in recent years has the characteristics of efficient heat preservation.

Load-bearing foam concrete: Used as a load-bearing material, and also has a certain energy-saving and thermal insulation effect. Normalerweise, it is bulk density.

Foamed concrete above 700 g/m3.

Load-bearing and heat-preserving foam concrete: Used as a self-supporting foam concrete. Normalerweise, it is foamed concrete with a bulk density of 500-600 kg/m3.

(2) Classification according to different foaming methods

Körperlich Zementschaummittel: Foaming agent for concrete: a foaming agent for concrete, which is based on surfactants, is foamed through a foam generator and mixed with a mixed slurry. The density of the foam concrete is adjusted by changing the number of bubbles. The foam concrete prepared by this method has good construction performance but is too dependent on the foaming machine.

Chemical foaming agent foam concrete: Use hydrogen peroxide or aluminum powder to release gas through a chemical reaction to make foam concrete. Die Temperatur des Betons und die Konsistenz der Schlämme beeinflussen die Schäumzeit und die Schaummenge, was als Nachschäumen bezeichnet werden kann.

Nach dem Mischen schäumte der Beton auf: Tenside verwenden, tierische und pflanzliche Schaummittel auf Proteinbasis, usw. in den Mixer einarbeiten,

Mit der Gülle verrühren, Hierbei handelt es sich um eine Methode zur Herstellung von Blasen durch Starten. Seine Mischzeit, Mischgeschwindigkeit, Konzentration.

Durch die Änderung der Materialpartikelgröße und andere Faktoren kann der Luftgehalt angepasst werden, und die Verarbeitbarkeit kann nur durch Rühren erreicht werden.

(3) Nach verschiedenen Aggregattypen

Polystyrolpartikelschaumbeton verwendet Polystyrolpartikel als Zuschlagstoff, Mischen Sie es mit Schaumbetonbrei, mischen und gießen.

Schaumbeton wird durch Injektion hergestellt.

Blähperlit-Schaumbeton: Schaumbeton, hergestellt unter Verwendung von expandiertem Perlit als Zuschlagstoff. Außerdem, there are lightweight aggregate foam concrete prepared with polyurethane particles, phenolic resin particles, vitrified microbead particles, and vermiculite.

(4) According to the different classification of the production process

Factory prefabricated foam concrete: refers to the foam concrete prefabricated in specialized chemical factories, such as foam concrete insulation board,

CLC blocks and foam concrete wall panels, usw.

On-site pouring of foamed concrete: such as ground thermal insulation layer, floor heating thermal insulation layer, wall surface pouring and large-volume filling.
