How many do you know about foam concrete cushion construction technology?

 Production of foam concrete

(1) Production of foam

The foam preparation adopts a special preparation machine (foam generator). The preparation principle is a physical method, and the foaming agent is input into the automatic foaming system through an air compressor to prepare foam.

(2) Production mixture

The foam concrete mixture preparation machinery is selected according to the needs of the project. First, add a certain amount of water into the mixer, and then put the weighed cement and admixtures into the mixer for mixing, and the time is not less than 2 minutes.

(3) Form foam concrete

After mixing the mixed material evenly, it is mixed with the foaming agent in the pipeline and transported by the high-pressure pump to the construction site for pouring and molding.

1. Grassroots cleanup

Use broom, shovel and other tools to clean the foam concrete base floor slab, so that there is no debris, hollowing, sanding, falling ash and other phenomena.

2. Elevation control and finished product protection

Before pouring the foam concrete cushion, a foam concrete block with the same proportion as the ground cushion concrete must be prefabricated in advance for ground reinforcement. The prefabricated height of the foam block is the design cushion height -5mm, so that cement mortar can be used on site. Fix the bottom and level it for use. Reinforce the ground according to the design requirements and the +50mm line in the building, and the setting principle is a plum-shaped layout. After the ground is reinforced, the finished products and semi-finished products of the previous process must be protected (such as the door, the lower sill of the fire door frame, the finished putty wall, etc.) and wrapped in advance to avoid pollution.

3. Formwork support and grassroots watering and moistening

According to the design requirements, the side formwork is supported according to the construction scope of the foam concrete cushion (such as: 300mm from the bathroom door, the kitchen door, the root of the radiator, etc.). The formwork is supported by square wood and bamboo plywood. It is necessary to ensure the verticality and flatness of the panel. After the formwork support is completed, water the ground base to moisten. Because the foam concrete has a low water absorption rate, it is not advisable to water too much to ensure that the ground is wet.

Overview of foam concrete

Foamed concrete is a kind of concrete material with light weight, heat preservation, heat insulation, fire resistance, sound insulation and frost resistance. The slurry can be self-leveling and self-compacting. It has good construction workability and is convenient for pumping and leveling. It is almost the same as all other building materials. It has good compatibility and the strength can be adjusted.

Application of foam concrete

(1) Used as a retaining wall. Mainly used as a rock wall for the port. Used as a lightweight backfill material behind the quay wall can reduce the vertical interception load and also reduce the lateral load on the quay wall. This is because it is a rigid body with good bonding performance. It does not exert lateral pressure on the quay wall along the periphery, and the settlement is reduced, and the maintenance cost is reduced, thereby saving a lot of expenses. Air bubble concrete can also be used to improve the stability of the embankment slope. It can replace part of the soil on the slope. As it reduces the quality, it reduces the force that affects the stability of the slope.

(2) Construct sports fields and track and field tracks. Use permeable foamed concrete with strong drainage capacity as a lightweight foundation, covered with gravel or artificial turf, as a sports field. The density of air bubble concrete is 800~900kg/m3. This kind of sports field can be used for hockey, football and tennis activities. Or it can be used as a track and field track by covering it with a 0.05m thick porous asphalt layer and a plastic layer.

(3) As a sandwich component. Air bubble concrete can be used as the inner core in the prefabricated reinforced concrete components, so that it has good performance of light weight, high strength and heat insulation. Foam concrete with a density of 400~600kg/m3 is usually used.

(4) Pipeline backfilling. Underground abandoned oil tanks, pipelines (with crude oil, chemicals), sewage pipes and other cavities are likely to cause fires or collapses. The use of bubble concrete backfilling can solve these problems with low cost. The density of air bubble concrete depends on the diameter of the pipe and the groundwater level, generally 600~1100kg/m3.

(5) Lean concrete fill. Due to the use of flexible hoses, bubble concrete has great workability and adaptability, so it is often used for lean concrete fills. If the requirement for thermal insulation is not very high, use lean concrete fill with a density of about 1200kg/m3, with an average thickness of 0.05m; if the requirement for thermal insulation is high, use lean concrete fill with a density of 500kg/m3 , The average thickness is 0.1~0.2m.

(6) Roof slope. Bubble concrete is used for roof slopes and has the advantages of light weight, fast construction speed, and low price. The slope is generally 10mm/m, the thickness is 0.03~0.2m, and the air bubble concrete with a density of 800~1200kg/m3 is used.

(7) The support of the bottom of the storage tank. Pour the foam concrete steps on the bottom of the steel storage tank (containing crude oil and chemicals). If necessary, it can also form a convex foundation. This can ensure that the support of the entire tank bottom is in the best stress state during welding. A continuous support allows the storage tank to adopt a thin plate bottom. At the same time, the convex foundation is easy to clean. The use density of air bubble concrete is 800-1000kg/m3.

(8) Used for landscaping. The foam concrete is made into a bulk density of 600-1000kg/m3, which can be used for garden rockery, garbage bins, tables and stools, etc.

(9) National defense (modern warfare uses information and advanced mobile equipment as attack tools). The bubble concrete can be used in military projects destroyed by enemy bombing, such as airports, important traffic roads, etc., to implement immediate repairs. Use our equipment and technology. The project that can be destroyed by the enemy can be quickly repaired, and the result of the experiment is that it can be used for aircraft to take off and land in 10 minutes after the repair, and the chariot can pass.
