What is cast-in-place foam concrete?
Concreto espumado moldado no local refere-se a uma espuma leve feita pela preparação física de uma solução aquosa de agente espumante, e depois adicionar a espuma a uma pasta feita de cimento, agregados, misturas, misturas, e água.
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 exemplo: 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.
Por exemplo: 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, stable quality, 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) Isolamento térmico: The thermal conductivity is 0.06-0.28W/(M.K), e a resistência térmica é de cerca de 10-20 vezes maior que o concreto comum.
2) Leve: The dry bulk density is 300-1600KG/M3, o que equivale a cerca 1/5 para 1/8 de concreto de cimento comum, 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%, o que é 5 vezes maior que o concreto comum. It has an effective sound insulation function.
6) Compressive resistance: The compressive strength is 0.6-25.0MPA.
7) Resistência à água: The cast-in-place foam concrete has low water absorption, bolhas fechadas relativamente independentes e boa integridade, which make it have a certain waterproof performance.
8) Durabilidade: the same as the life of the main project.
9) Simple construction: only need to use cement foaming machine to realize automatic operation, can realize long-distance transportation with a vertical height of 200 metros, and the workload is 150-300M3/working day.
10) Proteção 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) Economia: Low overall cost.
