Is your factory's roof, partition walls, or foundation bearing the added weight of traditional insulation? Lightweight concrete solves both problems simultaneously: reducing the building load to 350–600 kg/m³ while maintaining insulation, fire resistance, and long-term durability.

Dufago supplies lightweight concrete (aerated concrete) manufactured in a certified factory, delivered directly to construction sites throughout Central Vietnam – from Da Nang and Quang Nam to Quang Ngai.

What is lightweight concrete? How does it differ from regular concrete?

Lightweight concrete (or aerated concrete) is a type of concrete created by evenly distributing tiny air bubbles into a cement mixture, creating a characteristic porous structure that significantly reduces density compared to regular concrete.

According to American Concrete Institute (ACI) standardsThis material is commonly used to reduce building load and improve thermal insulation.

Note: Lightweight concrete is not a substitute for load-bearing structural concrete (beams, columns, and slabs). Appropriate applications include: insulation layers, partition walls, lightweight leveling, and thermal insulation.

Common applications of lightweight concrete in construction.

Lightweight concrete is most effective in the following three application groups, suitable for both civil and industrial construction projects.

Insulated roofs and floors

Pouring lightweight concrete over concrete roofs or top-floor slabs completely replaces EPS or polyurethane foam. Its outstanding advantages include: non-flammable and no toxic substances released in case of fire – a crucial factor for industrial and apartment buildings.

• – Effectively reduces floor/roof surface temperature thanks to a coefficient K = 0.1 W/mK
• – No additional components needed; pour directly onto the existing floor surface.
• – The additional load on the structure is only 350–600 kg/m³ instead of 2,400 kg/m³ for conventional concrete.

Lightweight partition walls

Constructing partition walls using lightweight cast-in-place concrete or precast panels – suitable for factories, offices, and warehouses requiring flexible space division.

• – Reduces the load on floors and beams compared to conventional brick walls.
• – Better sound insulation than single-layer drywall due to its solid structure.
• – Fast construction – no plastering required if aesthetics are not a high priority.

Industrial and infrastructure projects

Lightweight concrete is widely used in construction projects with specific load and temperature requirements:

• – The insulation layer for furnaces, kilns, and factories needs to maintain a stable temperature.
• – Leveling and infrastructure on weak soil – reducing the load on the foundation.
• – The subfloor for pipelines and utility trenches requires insulation.

Why choose Dufago's lightweight concrete pouring service?

Not every facility can control the uniformity of air bubbles in each batch. This is a crucial point that determines the actual density and insulation of the product – and it's where Dufago invests the most.

FAQ – Frequently Asked Questions about Lightweight Concrete

Can lightweight concrete withstand heavy loads?

Lightweight concrete achieves a compressive strength of 1.5–2.5 MPa after 28 days – sufficient for insulation, partition walls, and light leveling applications. However, it is not suitable for primary load-bearing elements such as beams, columns, and structural slabs. For these applications, conventional concrete or reinforced concrete should be used.

What is the appropriate density of lightweight concrete for insulated roofs?

For residential and light industrial roof insulation, a density of 400–500 kg/m³ is most common – balancing good insulation with sufficient rigidity for maintenance and foot traffic. Dufago provides specific advice based on the allowable load of each project.

Are lightweight concrete and aerated concrete different?

Essentially, they are the same product – 'aerated concrete' describes the formation mechanism (air bubble distribution), while 'lightweight concrete' describes the properties (low density). In the Vietnamese construction industry, these two names are used interchangeably.

How long does it take to ship from Dufago?

Typically, delivery takes 24–48 hours after order confirmation for projects within the factory's service radius. For large projects requiring high volumes, Dufago schedules deliveries according to the construction schedule to avoid site disruptions.

The price of lightweight concrete (aerated concrete) depends on many technical factors and actual construction conditions. Unlike conventional structural concrete, lightweight concrete is designed according to its density and intended use, so the cost can vary from project to project.

If your project is in the design or construction preparation phase, this is the best time to calculate the options – before the formwork is erected.

Concrete density

The higher the density, the greater the strength and the higher the material cost.

Concrete thickness

Construction volume

Large-scale construction projects are often more cost-effective due to: reduced transportation costs, optimized mix design, and continuous construction.

In addition to lightweight concrete, Dufago also offers... ready-mixed concrete Dufago provides services for structural elements such as foundations, beams, columns, and slabs. We offer site surveys and quotations within 24 hours for projects in Central Vietnam.
