Could you tell us about BELMIX ACC and its purpose?
Phani Kishore Chilukuri
BELMIX ACC is an advanced anti-carbonation coating designed to protect concrete and masonry surfaces from environmental degradation. Developed by Jayasree Techno Solutions, this coating provides exceptional resistance to environmental aggressors like water, carbon dioxide, sulfur dioxide, nitrogen oxides, chlorides, and UV radiation. Its elastomeric nature ensures superior crack-bridging while maintaining breathability, making it ideal for structures in aggressive or coastal environments.
Interviewer
Why is carbonation such a significant problem for concrete structures?
Phani Kishore Chilukuri
Carbonation occurs when carbon dioxide penetrates concrete and reacts with calcium hydroxide to form calcium carbonate. This process reduces the alkalinity of concrete, making it vulnerable to corrosion, cracking, and overall structural deterioration. Without protection, this can lead to reduced durability and high maintenance costs.
Interviewer
What makes BELMIX ACC different from other coatings?
Phani Kishore Chilukuri
BELMIX ACC is unique because it is a water-based acrylic co-polymer coating with a micro-porous structure. This structure blocks harmful gases while allowing moisture vapor to escape, reducing internal pressure that could otherwise cause damage. Additionally, its elastomeric properties enable it to bridge cracks, adapt to structural movements, and perform exceptionally well under harsh conditions like UV exposure and freeze-thaw cycles.
Interviewer
Can you elaborate on the technical properties of BELMIX ACC?
Phani Kishore Chilukuri
Absolutely. BELMIX ACC boasts impressive technical properties:- Carbon Dioxide Diffusion Coefficient: Equivalent to 200 meters of air at 300 microns dry film thickness.- Water Vapor Transmission Rate: 10 g/m²/day, ensuring breathability.- Elongation at Break: 350% at 20°C, offering excellent flexibility.- Rapid Chloride Permeability: Only 90 Coulombs, demonstrating high resistance to chloride penetration.- Adhesion Strength: 1.52 MPa on concrete, ensuring durability under stress.

How is the product applied, and what preparation is required?
Phani Kishore Chilukuri
The application process is straightforward:1. Surface Preparation: Remove contaminants such as oil, grease, or algae. For heavily contaminated surfaces, high-pressure water jetting or sandblasting is recommended.2. Priming: Apply a diluted primer to porous substrates to ensure better adhesion.3. Coating: Apply two coats of BELMIX ACC, each with a dry film thickness of 90–100 microns.4. Curing: Allow at least 16 hours between coats for optimal performance.
Interviewer
How does BELMIX ACC perform under real-world conditions?
Phani Kishore Chilukuri
BELMIX ACC has been rigorously tested to ensure high performance. For example, it shows zero water penetration under 5-bar pressure, retains gloss and color under prolonged UV exposure, and offers superior resistance to abrasion and freeze-thaw cycles.
Interviewer
What types of structures would benefit most from this coating?
Phani Kishore Chilukuri
It’s particularly effective for structures exposed to aggressive environments, such as coastal buildings and bridges, industrial facilities subject to chemical exposure, and any concrete surfaces requiring aesthetic and functional enhancements.
Interviewer
How does BELMIX ACC contribute to sustainability?
Phani Kishore Chilukuri
Sustainability is at the core of BELMIX ACC. Being water-based and non-toxic, it aligns with environmental compliance standards. By extending the lifespan of concrete structures and reducing maintenance needs, it also minimizes resource usage over time.
