Two types of cement foaming agents

Overview of cement foaming agent

The synthetic foaming agent used for concrete is a highly concentrated and efficient liquid used to produce lightweight foamed concrete. Foamed concrete is also called foamed lightweight concrete (CLC).

CLC concrete has great potential in the construction of honeycomb lightweight applications, and the use of the correct type of foaming agent will make a huge difference in product properties (such as the mechanical properties of concrete and its resistance, etc.). Synthetic foaming agents are chemical substances that reduce the surface tension of liquids and are widely used in the manufacture of blocks, bricks, CLC concrete, etc. worldwide. Compared with other foaming agents, when high density is required, it can be formed with less energy. It is strongly recommended for use in the construction industry, as the demand for lightweight concrete continues to increase over time.

The influence of cement foaming agent on the quality of foam concrete is very important. A good cement foaming agent can make high-quality foamed concrete. The foam produced by high-quality cement foaming agent has good stability and can be constructed in a low temperature environment. The one-time pouring height is more than twice that of similar cement foaming agents.

The foam produced by the protein foaming agent has good stability, its liquid film is tough, and its mechanical strength is good. It is not easy to crack or excessively deform under the extrusion of the slurry. In addition, it has self-holding water, and the water on the liquid film is not easy to lose under the action of gravity and surface tension. It can maintain the thickness and integrity of the foam liquid film for a long time, so the foam can be retained for a long time without breaking

Cement foaming agents are mainly divided into two types: one is vegetable cement foaming agent and the other is animal performance foaming agent. How to choose these two foaming agents? Let's take a look at the difference between plant cement foaming agent and animal foaming agent.

1. Plant cement foaming agent: Plant cement foaming agent is made of imported high-quality natural plant polymer materials through a series of complex chemical reactions. This product is light yellow pure transparent oily liquid. It is insensitive to hard water, non-toxic, tasteless, and has no sediment. The PH value is close to neutral, non-corrosive to cement and metal, and does not pollute the environment.

Advantages: the foaming agent is storage-resistant, not easy to deteriorate, excellent foaming performance, rich foam, and moderate foam stability. The foamed cement made with the foaming agent has the characteristics of low dosage, low cost and stable quality. Drum foaming agent (200kg) can produce about 500 cubic meters of foamed cement, so it is widely used in floor heating projects. In the roof insulation project, the construction cost can be significantly reduced.

Disadvantages: Since the foamed cement made from the foaming agent has a continuous inner hole shape, the foamed cement has good air permeability and poor impermeability, and cannot be used in anti-seepage projects. Compared with foam cement made from animal foaming agent of the same density, its thermal insulation performance and compressive strength are slightly impaired, so it is limited in some applications with special requirements. Due to the stability of the vegetable foaming agent foam, the thickness of the foamed cement poured at one time is generally not more than 200mm, otherwise the surface is prone to collapse.

2 Animal cement foaming agent: The animal cement foaming agent uses selected animal (cattle, sheep) keratin as the main raw material, and undergoes a series of hydrolysis reactions, heating to dissolve, dilution, filtration, and high temperature shrinkage. It is produced by foaming equipment and manufacturing process. Strict quality management in the production process. The product is a dark brown viscous liquid with low impurity content, a slight pungent odor, uniform quality, good quality consistency, good foamability, and good foam stability. It is a new generation of animal cement foaming agent.

Advantages: Compared with foam cement made of plant foaming agent, it has better sealing performance and higher heat resistance under the same density. Due to its excellent foam stability, its one-time pouring foam cement can reach more than 1.5 meters without collapsing, so it is suitable for the production of foam bricks, lightweight boards and lightweight walls.

Disadvantages: Due to the complex production process, the product cost is high. The foaming agent foams less than the vegetable foaming agent, and the consumption of foamed cement is high. There is a certain pungent odor, which can only disappear after being made into foamed cement.

Application of cement foaming agent

1. Foaming agent is used to make lightweight (clc) blocks and panels;

2. Blowing agent is used to fill the gap;

Foamed concrete is also very useful for filling voids. Because of its high mobility, it can even be poured into the most inaccessible places. It can be used for planned work, and can quickly provide stability and support in emergency situations;

3. Foaming A gentleman is used for roof insulation;

4. Foaming agent is used to mark CLC blocks, cast-in-place walls, bridge reinforcement wall structures, floor structures, lightweight prefabricated blocks, fire protection, sound insulation, etc.
