What is lightweight cement board?

Lightweight cement board is a sheet-type building material whose main components are Portland cement (70%), silica sand, reinforcing fibers, and additives. Lightweight cement board is manufactured in two standard sizes commonly found on the market:

1. Dimensions: 1220mm x 2440mm (Large format is common) is the ideal choice for large-area construction. This size minimizes the need for cutting and joining, saving time and labor costs.
2. 1000mm x 2000mm (smaller size) It is more suitable for constructions with narrow entrances, houses in alleys, or projects requiring construction at high floors where the volume of goods to be transported can be conveniently divided into smaller quantities.

The thickness of flexible cement boards ranges from 3,5mm to 20mm to meet diverse construction requirements, from ceiling linings to load-bearing floors.

What process is used to manufacture fiber cement boards?

Lightweight cement board factories produce the product through four steps: mixing raw materials, hydraulic pressing, heat treatment at 1.300°C, and cooling. This process utilizes high technology and is a closed system, ensuring consistent product quality.

1. The input materials, including Portland cement, fine silica sand, and reinforcing fibers (wood fibers or cellulose fibers), are fed into an automated mixing system to form a homogeneous mixture.
2. Next, this mixture is processed through a steam-hydraulic pressing method with sufficient compression force. This process involves rolling and compressing the material to create a strong bond according to the initially established dimensions and thickness.
3. Immediately after the pressing process is complete, the sheet is placed in a specialized drying oven, where the temperature reaches up to 1.300 degrees Celsius – a crucial heat treatment process that significantly increases the product's strength and hardness.
4. Finally, the cement boards will be cooled in a special chamber to balance the moisture and smooth the surface, completing the manufacturing process.

The entire production process is strictly monitored and inspected using modern automated machinery imported from Europe. This ensures that each cement board meets quality and aesthetic standards, satisfying the stringent requirements of the modern construction industry.
