What is cast-in-place foam concrete?
El hormigón celular colado in situ se refiere a una espuma liviana que se obtiene mediante la preparación física de una solución acuosa de agente espumante., y luego agregar la espuma a una lechada hecha de cemento, agregados, ingredientes, ingredientes, y agua.
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. Por ejemplo: bloque de hormigón celular, 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.
Por ejemplo: 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, calidad 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) Aislamiento térmico: The thermal conductivity is 0.06-0.28W/(M.K), y la resistencia térmica es aproximadamente 10-20 veces mayor que el concreto ordinario.
2) Ligero: The dry bulk density is 300-1600KG/M3, which is equivalent to about 1/5 a 1/8 of ordinary cement concrete, que puede reducir la carga total del edificio.
3) Integridad: 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) Aislamiento acústico: The cast-in-place foam concrete contains a large number of independent bubbles, y están distribuidos uniformemente. La capacidad de absorción acústica es 0.09-0.19%, cual es 5 veces mayor que el concreto ordinario. It has an effective sound insulation function.
6) Resistencia a la compresión: The compressive strength is 0.6-25.0MPA.
7) Resistencia al agua: The cast-in-place foam concrete has low water absorption, Burbujas cerradas relativamente independientes y buena integridad., which make it have a certain waterproof performance.
8) Durabilidad: Lo mismo que la vida del proyecto principal..
9) Construcción sencilla: only need to use cement foaming machine to realize automatic operation, can realize long-distance transportation with a vertical height of 200 metros, y la carga de trabajo es 150-300M3/día laborable.
10) Protección ambiental: 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) Economía: Low overall cost.
