What are the advantages of lightweight concrete panels?

Lightweight concrete panels are the perfect alternative to traditional concrete walls thanks to the following 6 advantages:

1. Superior insulation: Lightweight concrete panels are designed with foam structure or insulation materials such as EPS, ALC. Thereby helping to reduce the heat transfer coefficient to 0,1 - 0,2 W/mK (compared to traditional concrete of 1,5 - 2,0 W/mK) and reduce room temperature by 4 - 9°C.
2. Fast and flexible construction: With a weight of only 1/3 to 1/5 compared to traditional concrete (600 – 800 kg/m³), lightweight concrete panels are easy to cut and install. With a project of 100m², 4 skilled workers can construct and complete lightweight concrete panel cladding in just 2 – 3 days.
3. Diverse applications: Widely used for many items such as partitions, floors, walls, ceilings.
4. Effective fire protection: Thanks to its special structure with fire-resistant additives, lightweight concrete panels can withstand temperatures up to 1.200°C for 2-3 hours without deformation.
5. Health safety: Containing no asbestos – a substance that is seriously harmful to human health, lightweight concrete panels are manufactured from safe materials that do not emit toxic gases.
6. Environmental friendliness: Production process reduces CO2 emissions, contributing to protecting the living environment.
   

What are the limitations of concrete panels?

When choosing concrete panels, investors and contractors need to note the following 3 limitations:

1. Lower bearing capacity than monolithic concrete: Compared to traditional concrete (compressive strength 20 - 40 MPa), lightweight concrete panels only reach 3,5 - 7,5 MPa. Therefore, this material is not suitable for structures requiring high load-bearing capacity, such as foundations or columns with high loads. For projects requiring high mechanical strength, it is necessary to combine panels with steel reinforcement or steel frames.
2. High technical construction requirements: Panel assembly is not simply assembling concrete blocks, construction workers must have the skills to handle joints, ensuring the tightness of the project.
3. Not suitable for complex architectural designs: Panel is suitable for projects with simple, square designs. When applied to projects with many sophisticated details, curves or non-standard cross-sections, processing will take a lot of time and cost.

How many types of precast lightweight concrete panels are there?

To meet the diverse needs of construction projects, precast lightweight concrete panels are manufactured with 4 popular product lines: ALC/AAC lightweight concrete panels, CLC foam concrete panels, EPS lightweight concrete core panels, and Cemboard panels.

ALC/AAC lightweight concrete panels

Lightweight concrete panels ALC/AAC are construction materials produced from autoclaved aerated concrete. The main components include cement (20 – 30%), quartz sand or fly ash (50 – 60%), lime, gypsum and aluminum powder (0,05 – 0,08%). This small amount of aluminum powder acts as a foaming agent, creating the characteristic hollow structure of ALC/AAC. This superior property helps the concrete block have a dry weight of less than 1.000kg/m³.

CLC foam concrete panel

CLC foam concrete panel, or non-autoclaved lightweight concrete (Cellular Lightweight Concrete), is a building material with a closed-cell structure that accounts for 70-80% of the volume. The ingredients include cement (20-30%), fine sand or fly ash (40-50%), foaming agent, polypropylene or glass fiber and additives. The mixture is mixed well and cured under natural conditions, thereby reducing production costs compared to AAC/ALC.

Thanks to its inorganic properties, CLC panels do not emit smoke or toxic gases in the event of a fire, ensuring safety for living and working spaces. This material is also highly appreciated for its sound insulation ability of 43 - 60 dB, thanks to its closed-cell structure that helps to both absorb sound and reduce sound transmission more effectively than many traditional building materials.
