What is foam concrete? What is Foam Concrete? Is there any use for it?

Foam concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and mix the foam and cement slurry evenly. Then, through the pumping system of the foaming machine, cast-in-place construction or mold forming, a new type of lightweight thermal insulation material containing a large number of closed pores is formed by natural curing. Foam concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-relieving, environmentally friendly, energy-saving, inexpensive and non-combustible.

Lightweight concrete (foam concrete) is a concrete product containing a large number of fine closed pores and with considerable strength by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry by chemical or physical means according to the needs of the application, and after reasonable curing and molding. The production of lightweight concrete (foam concrete) is usually made by mechanical methods to prepare an aqueous solution of foaming agent into foam. Here's how:

The aqueous solution of foam agent is prepared into foam by mechanical method, and then the foam is added to the slurry composed of siliceous materials, calcareous materials, water and various admixtures, etc., which are mixed and stirred, poured and molded, and cured.

The density of foam concrete is small, the density grade is generally 300-1800kg m, the density grade of commonly used foam concrete is 300-1200kg m3, and the ultra-light foam concrete with a density of 160kg m3 has also been applied in construction projects. Due to the small density of foam concrete, the use of this material in the building structure such as internal and external walls, floors, floors, columns, etc., can generally reduce the weight of the building by about 25%, and some can reach 30%-40% of the total weight of the structure. Moreover, for structural components, if foam concrete is used instead of ordinary concrete, the bearing capacity of the component can be improved.

Therefore, the use of foam concrete in construction projects has significant economic benefits.

Foam concrete is a kind of lightweight porous concrete made by mixing and mixing, pouring and forming and steam curing by mechanical method to prepare foam, add it to the slurry composed of siliceous materials (sand, fly ash), calcareous materials (lime, cement), water and additives. It is a new type of building energy-saving material with waste utilization, environmental protection, energy saving, thermal insulation, sound insulation, low cost and non-combustibility. With its good characteristics, foam concrete is widely used in energy-saving wall materials, and has also been applied in other aspects.

At present, the application of foam concrete in China is mainly cast-in-situ roof foam concrete insulation layer, foam concrete surface block, foam concrete lightweight wall panel, foam concrete compensation foundation. However, by making full use of the good characteristics of foam concrete, it can be used in construction projects to expand its application field, speed up the progress of the project, and improve the quality of the project.

Foam concrete is a lightweight and high-strength cement-based insulation material, and the basic principle is to use a large number of closed pores in concrete to achieve the effect of lightweight, thermal insulation and heat insulation. Foam concrete is a new type of lightweight porous thermal insulation energy-saving material made of foam and cement (or adding aggregates such as fly ash, sand, slag, etc.) after mixing and pouring molding.

Scope of use

For building wall materials:

GS foam concrete is suitable for various types of lightweight aggregate blocks and slats, solid blocks, standard bricks, matching bricks, etc. in the design of frame structure of construction projects.

For the construction of long-span bridges:

The long-span bridge built of GS foam concrete can reduce the self-weight of the bridge and improve the seismic resistance and bearing capacity of the bridge deck.

For sewage treatment:

GS foam concrete can filter the garbage of sewage and adsorb oil and harmful substances.

For soilless culture:

GS foam concrete can be used for soilless cultivation of potted flowers and horticulture, which can retain water and fertilizer, keep the soil loose for a long time, prevent soil compaction, and be clean, hygienic and beautiful.

For rooftop garden greening:

GS foam concrete is used in rooftop gardens to reduce floor loads, protect soil from loss and quickly dredge stagnant water, and maintain soil moisture and fertilizer supply when it is hot and dry.

It is used for pipe insulation, kitchen and bathroom backfilling

GS foam concrete is used for the insulation of various air conditioning pipes, steam pipes and other pipes, which can reduce pipeline shrinkage and cold brittleness at low temperatures. Reduced heat loss at high temperatures. It is used for backfilling of kitchen basins and bathtubs in bathrooms, greatly reducing floor loads, and reducing water seepage and leakage caused by seasoning settlement and surface cracking.

It is used for floor cushion and moisture-proof layer

GS foam concrete is used for cushioning to improve the thermal insulation, heat insulation, sound insulation and bearing capacity between floors; It can facilitate the layout and installation of pipelines on the ground. It is used for moisture barrier and can also prevent the re-moisture of the floor; Keeping the floor of the car building dry is quite beneficial for protecting all kinds of wooden floors, plastic boards, and ceramic floors from deformation and fading, as well as for the basement moisture-proof and waterproof.

For chimney insulation lining:

The hesitant thermal conductivity of GS foam concrete is very small, and it is widely used in the insulation layer of chimney kiln, which can be thermal insulation, high temperature resistance, acid and alkali resistance, and greatly extend the life of the chimney.

It is the concrete with the addition of polystyrene particles to play a role in heat preservation.

1. It can play the role of a retaining wall, for example, in the port, the position behind the shore wall of Kaichong Port is filled with a little foam concrete, so that the load in the vertical direction is reduced, which can help the shore wall reduce the load in the lateral position.

2. Play the role of pipeline backfill, such as underground abandoned sewage pipes, pipelines, etc., and use some foam concrete for backfilling, which can solve the later problems and reduce disposal costs.

3. It is used as a sandwich component. For example, a little foam concrete is used as the inner core in reinforced concrete components, so that it can have excellent thermal insulation and light weight.

1. Foam concrete has a certain waterproof performance, but it is not particularly good, and the water absorption rate of foam concrete is not particularly high, so it has a certain waterproof performance relatively speaking.

2. Foam concrete is relatively common in the construction industry, and the characteristics of this kind of concrete are that the durability is relatively good, and it is also more convenient in the production and processing. 3. Foam concrete is also very light due to its relatively small density, and the thermal insulation performance of this material is also very good, the sound insulation and fire resistance are relatively good, and the service life is relatively long.

Foam concrete can be used for bathroom backfill, and the water absorption rate of foam concrete is relatively low, so the waterproof performance of this concrete is also very good. At the time of construction, as long as the construction is in accordance with the standard, then there is no problem with using this concrete to backfill.

The above is about the content of foam concrete used in the first problem, this material has a wide range of applications, for example, it can be used to build sports fields, it can also be used to backfill pipelines, and it can also be used for roof insulation, foam concrete can be seen on many construction sites.

1. Bubble concrete is a new type of lightweight insulation material containing a large number of closed pores formed by natural curing.

2. Foam concrete is a kind of lightweight, thermal insulation, thermal fire-resistant, soundproof and frost-resistant concrete materials, the slurry can be self-leveling, self-compacting, good workability of construction, easy to pump and leveling, and almost all other building materials have good compatibility, and the strength can be adjusted.
