Жеңіл көбікті бетон туралы сіз білуіңіз керек

What is lightweight көбік бетон and how to make foam concrete?

Жеңіл көбік бетон comes into being through a series of complex operations. Бірінші, through the foaming system of the foaming machine, the foaming agent is fully foamed mechanically, foaming agent and foam slurry mixing with water during the time. And then finish the cast-in-situ construction or mold forming through the foaming machine pumping system. Ақырында, through the natural curing, a new lightweight thermal insulation material contains a lot of closed porosity is formed. Lightweight foam concrete belongs to the bubble insulation material. Оның көрнекті ерекшелігі - ол бетонның интерьерінде жабық көбік тесігін құрайды, which brings it light quality and the heat preservation heat insulation.

What is the relationship between lightweight көбік concrete and aerated concrete?

Lightweight concrete is a special type of aerated concrete. Its pore structure and material properties are close to common aerated concrete, the main difference between them existing only in the shape of pores and aeration means.

What are the characteristics of lightweight concrete?

1. Жеңіл салмақ: lightweight foam concrete has a low density. And its density grade is generally 300-1800kg/m3. The most common-used lightweight foam concrete is of the density between 300-1200 кг/м3.

2. Good thermal insulation performance: because lightweight concrete contains a large number of closed small pores, it has good thermal performance. Басқаша айтқанда, it has good thermal insulation performance, which ordinary concrete does not have. Жалпы, the density of lightweight concrete is in the range of 300-1200 кг/м3, thermal conductivity between 0.08-0.3w/(m·K), және жылу кедергісі шамамен 10-20 times of ordinary concrete.

3, Sound insulation and fire resistance: lightweight foam concrete is a kind of porous material, so it is also a good sound insulation material. In the building floor and highway sound insulation board, the top floor of the underground building can use this material as sound insulation layer. Lightweight foam concrete is also an inorganic material. Ол жанбайды, therefore it has good fire resistance, which often is used in the building so that it can improve the fire performance of the building.

4. Good overall performance: it can be on-site pouring construction, and can be closely combined with the main project.

5. Low elastic shock absorption: the porosity of lightweight concrete makes it have a low elastic modulus, so that it has a good impact load absorption and dispersion.

6. Күшті су өткізбейтін өнімділік: cast-in-place lightweight foam concrete has a low water absorption rate, relatively independent closed bubbles and good integrity, so that it has a certain waterproof performance.

7. Great durability: it can be used for a long time the same as the main project life.

8, production and processing convenience: lightweight concrete not only can be produced in the factory into a variety of products, but also can be on-site construction, directly cast into the roof, ground and wall.

9. Good environmental protection performance: the materials needed for lightweight concrete are cement and foaming agent, which is neutral and free of harmful substances such as benzene and formaldehyde, avoiding environmental pollution and fire risk.

10. Ыңғайлы құрылыс: just by using a cement foam machine, you can achieve automatic operation, and can pump to achieve a vertical height of 200 meters long-distance transportation. The workload is 150-300 cubic per working day.

What are the applications of lightweight көбік бетон?

1.It can be used as a retaining wall. The lightweight foam concrete is primarily used as a the rock wall in a harbor. Using light backfill material behind shore wall can reduce vertical load and lateral load of shore wall.

2.It can be used to build sports grounds and field tracks.

3.It can be used as a sandwich component. In the precast reinforced concrete components, lightweight foam concrete can be used as the inner core, жеңіл салмақта жақсы өнімділікке ие болу үшін, жоғары беріктік пен жылу оқшаулау. The density is usually 400-600kg /m³.

4. It can be used in the field of pipeline backfill. Underground waste oil tank, pipeline (құрамында шикі мұнай бар, химиялық заттар), sewage pipe and other holes are easy to lead to fire or collapse, the use of foam concrete backfill can forestall those future problems. besides, its cost is also very low. The density of foam concrete depends on the diameter of the pipe and the water table, and usually the density is 600-1100kg/m³. .

5.It is often used for lean concrete filling in the layer. Due to the use of flexible hose, foam concrete has a great degree of work and adaptability, so it is often used for lean concrete filling. If the insulation requirement is not high, the density is 1200kg/m³. The average thickness of lean concrete filling is 0.05m. For high insulation requirements, the density is 500kg/m³. And its average thickness is 0.1-0.2m.

6.It is often used in roof slope. Foamed concrete is used for roof slope, which has the advantages of light weight, жылдам құрылыс жылдамдығы және төмен баға. The slope is generally 10mm/m, қалыңдығы 0,03-0,2 м, and the density is 800-1200kg /m³.

7.It is used to support for the bottom end of the storage tank. Pouring steps of foamed concrete on the bottom of the bottom of the steel storage tank (with crude oil and chemicals) can form a convex foundation if necessary, so as to ensure that the support of the entire bottom of the tank is in the optimal stress state during welding. This continuous support can make the tank adopt the bottom of the thin plate tank. Convex foundations are also easy to clean. The density of foamed concrete is 800-1000kg\m³ .

8.It can be used for landscaping. The bulk density of foamed concrete is 600-1000kg/m³ , оны бақша рокері үшін пайдалануға болады, қоқыс жәшігі, table stool and so on.

9.It can be used in the field of national defence (modern warfare uses information and advanced mobile devices as the attack tool). The foam cement can be used in military engineering. Мысалы,when the airport has been damaged by the enemy bombing, foam concrete can be used to make important implement immediately repair.

10. Other uses: Foam concrete can also be used for firewall insulation filling, sound insulation floor filling, tunnel liner backfilling. Сонымен қатар, it can be used in the field of the isolation of power and water pipelines.
