The reason why colored sand maintains its paving function even after more than 15 years.

Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!

We will explain the reasons why the "permeable and water-retaining blast furnace slag pavement (color sand)" has maintained its paving functionality even after more than 15 years since installation. Color sand meets all five "pavement requirements" expected for pedestrian areas and maintains high performance among pedestrian pavements. The characteristic of the blast furnace water-quenched slag used as aggregate, "latent hydraulicity," not only enhances strength but also provides excellent permeability and water retention due to its porous structure. Furthermore, in response to the repeated action of freezing and thawing during winter, it prevents the deterioration of the pavement surface by relieving the pressure caused by the volume expansion of moisture during freezing. Additional explanations, such as "representative examples of sites that have maintained paving functionality for over 15 years," can be found through external links. 【Technical Information Introduction】 ■ 20 years since the development of color sand ■ High performance maintained as pedestrian pavement ■ Technical reasons for maintaining paving functionality after more than 15 years / representative examples of sites *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.
