Explanation of the foam concrete floors, foam concrete construction process

Delivery time:
Foam concrete construction technology requirements This case is suitable for heat preservation and heat insulation foam concrete roof and indoor cushion layer.
Foam concrete equipment production process will be the end of the raw material of fly ash, coal gangue or stone, such as one through to the DPJX host and cement and foaming agent stirring 8 minutes, and then after foaming machine feeding system in pouring bin, pouring bin pump by pouring to the mold, slurry in mould 2-4 hours to draw forming brick, natural curing to the factory for seven days.
The concrete construction schemes sorting summary:
1, construction preparation:
1.1 material and main equipments:
1.1.1 foaming agent: HT001 type composite polymer foaming agent.
1.1.2 cement: using 32.5 ordinary Portland cement or composite Portland cement.
1.1.3 fly ash: the level of fly ash.
1.1.4 HT - 18 foaming machine, diluted water bag, the scale, carts, containers, Chinese catalpa, pointed shovel, scraping bars, wood trowel, rubber hoses, iron chisel, wire brush, etc.
1.2 operation conditions:
1.2.1 the main structure engineering quality has completed the acceptance procedures, doorcase installed, (daughter) wall had been playing around + 50 cm level elevation lines.
1.2.2 across the floor of warm, defend pipeline has been installed, tube hole has been pouring concrete with fine stones, and has set up a tamping compaction.
1.2.3 related appliances embedded project has been completed.
1. The requirement of the foam concrete has been determined by debugging.
2, process basic level processing - find elevation, play horizontal line - ingredients pulping, high-pressure pipe, construction surface of casting, leveling, natural curing.
3, process requirement
3.1 basic level processing: in casting foam concrete insulating layer (or pad) before the concrete floor at the grass-roots level, the loose on the base concrete, such as floating pulp with a chisel shave, use wire brush to brush off the slurry skin, and then use the broom.
3.2 find elevation level line: elevation lines, according to the level of + 50 cm on the wall of insulating layer level down, conditional when can play around the wall.
3.3 ingredients pulping: cement and fly ash, measurement after join mixer, will rise to about ten percent aqueous solution foaming agent made from 1 ㎜ fine uniform bubbles, and then add the foam mixer;Foam and cement mixing, made of foam concrete slurry.
3.4 high pressure pipeline: start the foaming machine, will be made of foam concrete slurry with casting pump pumping to face;
3.5 pouring shape: pouring concrete slurry bubble to the construction plane.
3.5.1 track of every mixing foam concrete slurry should be debugging sure slurry density in about 600 kg/m3, determine the foaming situation normal rear can construction.
3.5.2 construction pouring observe, check the foam slurry casting size, liquidity, and strictly control the thickness of the casting, the surface roughness.
3.5.3 sprinkling water on the grassroots wet before laying foam concrete, then starting from the end.
After 3.6 leveling: foam concrete initial setting to level elevation lines and leveling line to check on the wall roughness, high shovel, concave.With horizontal wooden poles shave is flat, again with wood float rub flat surface.Floor requires slope, should according to the design requirements of slope construction.
3.7 after the foam concrete, natural curing 3 to 7 days, can reach the person before in other projects.
4, quality standards,
Thickness and strength of 4.1 production should meet the requirements of the contract design.
4.2 thermal insulation layer (or pad) before laying, below a layer of surface should be wet.
Large area such as industrial factory building, hall, the hall 4.3 foam cushion should segment pouring concrete.Partition period should be combined with the deformation seam position, different types of building ground connection and the location of the equipment foundation.
