ECA CSR is a specialized surface retarder designed for creating washed concrete products using a negative application process. It comes in ten different varieties, each intended for achieving varying levels of aggregate exposure depths in the finished concrete surface. While the exposure depths provided are typical standards, actual results may vary based on factors such as the type of cement used, the water-cement ratio, aggregate grading, and the quantity of cement employed in the mix.
ECA CSR is a versatile surface retarder that enhances both the aesthetics and functionality of concrete applications. It is crucial in achieving desired washed concrete finishes for façade coverings, soundproof walls, landscaping
features, and specialized concrete products. Its adaptability makes it especially valuable in architectural projects and the production of intricate forms, helping to maintain the quality and durability of concrete while achieving desired aggregate exposure depths.
• Provides flexibility in achieving different aggregate exposure depths to suit specific design preferences
• Requires only a single coat of formwork for each application, making it cost-effective
• Concrete can be poured after the weather-dependent drying time is met, streamlining the construction process
• Sample tests can be conducted to fine-tune the concrete mix’s vibrational qualities
• Can be used with new, polymer-modified casings, alkaline surfaces should be neutralized before the initial ECA CSR application through cleaning
