ZDM Добавка для отделки бетона is a revolutionary concrete surface treatment material engineered to optimize cement hydration efficiency.By enhancing hydration efficiency and binding surface moisture, the product improves workability, reduces surface permeability, minimizes plastic shrinkage cracking, and slows moisture evaporation. It enables faster surface closing without additional water application and delivers superior flatness, wear resistance, and long-term durability — even under harsh weather conditions.With 0 g/L VOC content, it is environmentally friendly and suitable for modern sustainable construction standards.

Concrete Finishing Additive – Technical Description

The Добавка для отделки бетона is a high-performance surface treatment solution designed to significantly improve the finishing quality and workability of concrete.

It effectively reduces the surface friction coefficient during finishing operations. Based on practical engineering experience, the friction coefficient can be reduced from approximately 0.6 to 0.3, greatly enhancing the smoothness and efficiency of troweling.

The additive also improves the rheological properties of concrete by optimizing the balance between yield stress and plastic viscosity. While maintaining proper workability, it enables a smoother finishing process. Studies indicate that the yield stress can be reduced by 15%–20%, facilitating easier surface treatment.

In addition, the product enhances surface densification. Test results show that the surface porosity of concrete can be reduced from around 12% to 8%, leading to improved surface strength and wear resistance.

From a microstructural perspective, the additive promotes a more uniform distribution of cement hydration products, forming a more regular crystalline structure. This contributes to improved surface flatness and a higher-quality finish.

In practical applications, the use of this additive significantly reduces surface defects such as tearing and drag marks during finishing. The defect rate can be reduced to below 5%, greatly improving the overall appearance quality of the concrete surface.

The product demonstrates excellent compatibility with various types of cement, including Portland cement and slag cement, consistently enhancing finishing performance. It can improve finishing efficiency by over 30%.

Furthermore, the additive forms a functional thin film on the concrete surface, which enhances surface hardness and provides hydrophobic properties. This can reduce water absorption by approximately 25%.

According to standard testing, the wear resistance of the concrete surface can be improved by 40%–50%, significantly extending the service life of the structure.

In mix design optimization, the proper use of the finishing additive can also reduce water demand and allow for a 5%–8% reduction in cement consumption, while maintaining the required strength.

How It Works

The additive reacts with calcium hydroxide (free lime) in cement to form additional calcium silicate hydrate (C-S-H) — the primary compound responsible for concrete strength.

This process:

• Converts inactive components into useful binding material
• Increases surface slurry density
• Enhances surface compactness and strength

At the same time, it slows down moisture evaporation from the surface, preventing premature drying.
