What is cast-in-place foam concrete?
El formigó espumat colat al lloc es refereix a una escuma lleugera feta preparant físicament una solució aquosa d'agent espumant, i després afegint l'escuma a un purín fet de ciment, agregats, mescles, mescles, i aigua.
The application of cast-in-place foam concrete can be divided into two categories:
1. Cast-in-place foam concrete is mainly made of products. Per exemple: foam concrete block, foam concrete lightweight partition wall, foam concrete cultural stone, foam concrete garden application, etc.
2. The cast-in-place foam concrete is mainly cast on-site.
Per exemple: backfilling (landfilling of garbage dumps, road and bridge applications, load-reducing filling of tunnel entrances, subway load-reducing filling, etc.), foam concrete cast-in-place walls, etc. Because foamed concrete has the characteristics of environmental protection, simple construction and operation, qualitat estable, and can be poured on-site. The foamed concrete poured on site is called cast-in-place foamed concrete or cast-in-place foamed cement.
1) Aïllament tèrmic: The thermal conductivity is 0.06-0.28W/(M.K), i la resistència tèrmica és d'aproximadament 10-20 vegades la del formigó normal.
2) Pes lleuger: The dry bulk density is 300-1600KG/M3, which is equivalent to about 1/5 a 1/8 of ordinary cement concrete, which can reduce the overall load of the building.
3) Integrity: On-site pouring construction is closely integrated with the main project, without boundary gaps and ventilation pipes.
4) Low elasticity and shock absorption: The porosity of cast-in-place foamed concrete makes it have a low elastic modulus, so that it has a good absorption and dispersion effect on impact loads.
5) Sound insulation: The cast-in-place foam concrete contains a large number of independent bubbles, and they are evenly distributed. The sound absorption capacity is 0.09-0.19%, which is 5 vegades la del formigó normal. It has an effective sound insulation function.
6) Compressive resistance: The compressive strength is 0.6-25.0MPA.
7) Resistència a l'aigua: The cast-in-place foam concrete has low water absorption, bombolles tancades relativament independents i bona integritat, which make it have a certain waterproof performance.
8) Durabilitat: the same as the life of the main project.
9) Construcció senzilla: only need to use cement foaming machine to realize automatic operation, can realize long-distance transportation with a vertical height of 200 metres, and the workload is 150-300M3/working day.
10) Protecció del medi ambient: The raw materials required for foamed concrete are cement and foaming agent. The foaming agent is neutral and does not contain harmful substances such as benzene and formaldehyde, which avoids environmental pollution and fire-fighting hazards.
11) Economy: Low overall cost.
