The Challenge
Carbonation of reinforced concrete is one of the most common forms of deterioration in buildings and infrastructure. Carbon dioxide from the atmosphere reacts with the concrete, leading to a loss of alkalinity and subsequent corrosion of the reinforcing steel. Structural integrity can therefore become severely compromised so it is critical to protect both new and existing structures.
The Solution
MRO 4021 Rainshade has high diffusion resistance against CO2 reducing the rate of carbonation. It is water vapor permeable and has very good resistance against weathering and ageing.
The Result
WHY MRO...
MRO 4021 Rainshade can ensure that concrete structures/ buildings remain visually attractive throughout their lifespan and avoid expensive and disruptive repair and maintenance work further down the line.
APPLICATION CASE HISTORY OF A PRIVATE BUNGALOW IN KERALA
PROBLEM
Reinforced concrete is not as durable as once anticipated and further protection is often necessary in order to achieve the desired design life.
The owner of the bungalow was concerned about the protection and enhancement of concrete structures especially as it was exposed to heavy rain and had a risk of cracking and he wanted to protect it from atmospheric gases like CO2 and chlorides.
CUSTOMERS BENEFIT
- High diffusion resistance against CO2 reducing the rate of carbonation
- Water vapor permeable
- Very good resistance against weathering and ageing
- Preventive protection for new reinforced concrete structures exposed to aggressive environments
- Able to withstand extreme temperature up to +80°C without deterioration, the coating remains unaffected by exposure to direct sunlight even in most aggressive of climates.
- Coating is designed to last for up to 15 years.
