Proposal for Improving Concrete Surfaces and Extending the Lifespan of Concrete Structures

Introducing a special pro-con sheet that combines water absorption, permeability, and water retention!

The Procon sheet can be simply applied to the formwork to remove pinholes and voids on the concrete surface, resulting in a smooth surface. Additionally, it absorbs excess water from the concrete surface, which in turn reduces the water-cement ratio, and the sheet's moisture retention function promotes the hydration reaction of the concrete surface, improving its quality. Furthermore, the time taken to reach the critical concentration for steel corrosion is 1.7 times longer than without the sheet, contributing to the longevity of concrete structures. 【Features】 ■ Compressive Strength: The mix is the same, and equivalent (Compressive Strength: 40.0⇔41.1 N/mm²) ■ Water Absorption Rate: Can be reduced by 50% (Water Absorption Rate: 1.0%→0.5%) ■ Abrasion Resistance: Can be improved by 56% (Weight Reduction: 2.5g→1.1g) ■ Permeability: Can be improved by 48% (Permeability Coefficient: 0.128→0.066) ■ Carbonation: Can be reduced by 30% (Carbonation Depth: 8.6mm→6.0mm) *For more details, please download the PDF or feel free to contact us.
