Characteristics And Functions Of Cement Foaming Cement

Cement foaming is divided into two types: physical foaming and chemical foaming. Physical foaming uses an air compressor (i.e. foaming machine) to pressurize the foaming agent to form a foam with a certain tension, and then combine the foam with cement. Stir the slurry simultaneously. During the mixing process, the cement expands. When the expansion effect reaches a preset ratio, foam cement can be formed. Chemical foaming refers to adding a foaming agent (liquid/powdered solid) to the cement slurry for stirring, and a chemical reaction occurs to release gas, causing the volume of the cement to expand continuously. The expansion effect reaches the preset state and foam cement is formed. Foamed concrete is made by mechanically fully foaming the foaming agent through the foaming system of the foaming machine, mixing the foam and cement slurry evenly, and then using the pumping system of the foaming machine for cast-in-place construction or mold forming. Natural is a new lightweight insulation material containing a large number of closed pores formed by solidification. ###Foam concrete is made by using surfactants to generate foam, then mixing it with cement slurry to solidify and harden naturally. Foam cement is made of hydrogen peroxide and other admixtures, and uses hydrogen peroxide to release oxygen to generate foam.

2. The difference between foam cement and foam concrete. I would like to know about the characteristics of foam cement.

Foamed cement generally refers to insulation (sound insulation or filling) materials composed of foaming agent and cement (a small amount of admixtures, water is not counted, and fillers such as fly ash); foam concrete generally refers to the above ingredients, aggregates (with Filling) light, medium and heavy-duty insulation (sound insulation, filling) materials. The new standard strictly refers to foam concrete, which was the common name for foam cement in the previous industry. In the new standards, foam concrete combines the advantages of fire protection, thermal insulation, sound insulation, light weight, structure (partial load-bearing walls), low cost, and mechanized construction. It has begun to be widely used in construction in northern and northern regions. At present, floor heating, roof insulation and foundation filling technologies have matured, low-price competition has begun, and cast-in-place wall (self-insulation) technology is being applied and promoted.

10What are the uses of foamed cement insulation boards?

It is a non-combustible material, non-toxic, environmentally friendly and low-carbon. It is a new type of material that is strongly advocated. Its fire resistance reaches A1 level. This product has the characteristics of high compressive strength (compared to plastic foam), low thermal conductivity, strong bonding with concrete, consistent expansion coefficient, and consistent service life with the building. This product is mainly used for roof insulation panels and interior and exterior wall insulation panels. The bonding mortar is directly bonded to the cement mortar and used as the coating surface of the exterior wall insulation board. Waterproof and crack-resistant mortar and fiberglass mesh can be used directly as the protective layer. . When pasting ceramic tiles, you can hang steel wire mesh or use plastic anchors, and apply anti-crack mortar on the outside to paste the ceramic tiles. ###The use of foam cement as roof insulation material mainly solves the problem of greatly improving the bonding force and adhesion between the insulation layer and the floor base. In the past, floor heating construction mostly used boards as the insulation layer, which could not be well combined with the original base surface and had no effective bonding, resulting in delamination, hollowing, cracking and other disadvantages. The foam cement body is used as the insulation layer, so that the foam cement insulation layer can fill the small uneven base surface of the original floor and can firmly grasp it to form a strong bonding performance.construction

11What is the construction method of foam cement cast-in-place roofing?

First, the construction method of the foamed cement insulation layer: (1) Mark the thickness and slope of the insulation layer around the parapet of the roof under construction. (2) Use a special mixer to stir the new foaming agent, cement (or mixture of cement, fly ash, etc.), water, etc. into uniform fluid foamed cement, and then pour it onto the roof using a template (large equipment can also use foaming cement from The ground is pumped directly to the roof and poured directly) to achieve the corresponding thickness. (3) After the roof insulation layer is completed, no one will enter the building or bear any load for 2-3 days. Furthermore, for the construction method of floor heating foam cement insulation layer, most of them adopt the so-called "self-leveling" construction method, which uses the fluidity of foam cement to level naturally. 1. To achieve "self-leveling", the activity of floor heating foam cement needs to be improved. The main method is to increase the water-cement ratio. The direct consequence of increasing the water-cement ratio is that the foam cement is easy to loosen and segregate, the strength is reduced, and the thermal insulation and sound insulation properties are reduced. At the same time, due to the large water content, foam cement shrinks greatly and hollow cracks are prone to occur. 2.In order to ensure that the floor heating foam cement insulation layer has a certain strength, in the "self-made"

12What is foam cement? What are the characteristics of foamed cement?

Foam cement is a bubble-like insulation material. It is foamed through the foaming system of the foaming machine. The foam and cement are mixed evenly and then constructed through the foaming machine system to form a new type of cement. The most prominent feature of lightweight insulation materials is that there are foam holes inside the concrete to insulate the concrete. Cement foaming uses cement as raw material. Mix cement with water and add a foaming agent. In this way, the cement will grow to 2 to 3 times its original size. There is a small closed air hole in the middle. Cut it into foam cement insulation board. Then, foamed cement insulation board has good fire protection, heat preservation and waterproof properties. Mainly used for exterior wall insulation and fire isolation belts. This is a new product in the building materials industry. It is currently being promoted vigorously. Developed provinces and cities require it to be above 30m. use this product. ###Foaming cement is a method of mechanically fully foaming the foaming agent through the foaming system of the foaming machine, mixing the foam and cement slurry evenly, and then instantaneously pouring or pouring it through the pumping system of the foaming machine.

18What are the standards for foam cement?

Foaming cement is to mechanically fully foam the foaming agent through the foaming system of the foaming machine, and mix the foam and cement slurry evenly, and then use the pumping system of the foaming machine for cast-in-place construction or mold forming. A new lightweight insulation material containing a large number of closed pores formed by natural solidification. It is a bubble-like thermal insulation material whose outstanding feature is the formation of closed foam pores inside the concrete, making the concrete lightweight and insulating.

19. What is the construction method of floor heating foam cement? Is there any expert who can share it?

1. To achieve "self-leveling", the activity of floor heating foam cement needs to be improved. The main method is to increase the water-cement ratio. The direct consequence of increasing the water-cement ratio is that the foam cement is easy to loosen and segregate, the strength is reduced, and the thermal insulation and sound insulation properties are reduced. At the same time, due to the large water content, foamed cement shrinks greatly and hollow cracks are prone to occur. 2. In order to ensure that the floor heating foam cement insulation layer has a certain strength, in the "self-leveling" construction method, while maintaining an increased water-cement ratio, the method of increasing the cement dosage is generally used. Generally 1M3 is used. The cement dosage of foam cement is about 400KG, and the bulk density of foam cement is greater than 500KG/M3. In this way, the thermal conductivity is greatly increased, but the thermal insulation performance is significantly reduced. 3. The "self-leveling" construction method is generally combined with pumping. During the pressurized pumping process of foam cement, the bubble crushing rate is about 25%. The moisture formed by the collapse of a large number of bubbles further increases the water volume, and coupled with the disturbance of the pump, the foam cement is more likely to segregate. After on-site inspection, it was found that part of the cement slurry settled at the bottom and the thickness of the foamed cement insulation layer reached more than 1CM.

20What is the bulk density standard of foam cement board?
