The reason why colored sand is strong against "freeze-thaw" cycles.

The reason why colored sand is strong against "freeze-thaw" cycles.

Introducing technical information about permeable blast furnace slag pavement "Color Sand"!

This document explains the reasons why "permeable and water-retaining pavement materials (color sand)" are strong against "freeze-thaw" cycles. Color sand is a pedestrian pavement material that possesses permeable and water-retaining functions while being sufficiently resistant to the repeated effects of freeze-thaw cycles in winter, making it "strong against frost damage." Among our pavement composition, the "filter layer" made from high furnace slag pavement, which is the aggregate of this pavement material, has a significant effect in suppressing "frost heave" when used alone. Furthermore, in freeze-thaw tests conducted at the Central Testing Laboratory of the Building Materials Testing Center, no cracking or destruction occurred even after completing 200 cycles. 【Excellent Features of the Aggregate (High Furnace Slag)】 ■ Porous Structure - Numerous fine voids relieve pressure caused by volume expansion during freezing. ■ Potential Hydraulicity - The main components of water-quenched slag (silica, alumina, lime, magnesia) solidify over time due to repeated water infiltration. ◎ Sufficiently resistant to the repeated effects of freeze-thaw cycles. *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

The technical basis of "permeable blast furnace slag pavement" that achieves both permeability and water retention.

The technical basis of "permeable blast furnace slag pavement" that achieves both permeability and water retention.

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

We will explain the technical basis of "Permeable and Water-retaining Blast Furnace Slag Pavement (Color Sand)" that achieves both permeability and water retention. All of our paving materials use "granulated blast furnace slag" as the main aggregate. The aggregate itself has a fine porous structure, allowing it to provide both permeability and water retention. While typical permeable paving materials achieve permeability at a "point," our paving materials achieve permeability over a "surface" due to the nature of the aggregate itself, resulting in less clogging and maintaining permeability performance over a long period. Additionally, by cleaning with high-pressure washers, the permeability can be restored to about 80%. Further explanations regarding "permeability performance" and "water retention performance" can be found through external links. [Technical Information Introduction] ■ Reasons for achieving both permeability and water retention ■ Permeability performance ■ Water retention performance ■ Our product lineup *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

About the characteristics and benefits of blast furnace crushed slag used in colored sand.

About the characteristics and benefits of blast furnace crushed slag used in colored sand.

Introducing technical information about permeable blast furnace slag pavement "Color Sand"!

This explains the characteristics and benefits of the blast furnace crushed slag used in "permeable blast furnace slag pavement (colored sand)." The "blast furnace crushed slag" used as aggregate in our paving materials is a byproduct generated simultaneously when producing pig iron from a blast furnace at major steel manufacturers. It can be easily separated as it floats on top of the molten pig iron. In addition to contributing to the reduction of environmental impact, it has characteristics such as excellent gradation balance due to its uniform particle size. Further explanations on topics such as "What is steel slag?" and "Characteristics and general applications of blast furnace slag" can be found through external links. 【Introduction of Technical Information】 ■ What is "steel slag"? ■ Characteristics and general applications of "blast furnace slag" ■ Reasons for adopting "blast furnace crushed slag" - Reduction of environmental impact, porous shape, latent hydraulicity, high internal friction angle, uniform particle size, safety *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

Technical basis for the permeability coefficient of permeable paving material "Color Sand"

Technical basis for the permeability coefficient of permeable paving material "Color Sand"

Introducing technical information about permeable blast furnace slag pavement "Color Sand"!

This document explains the technical basis for the permeability coefficient in "permeable blast furnace slag pavement (colored sand)." Our paving material uses granulated blast furnace slag as a raw material, which falls under the classification of sand and gravel. Therefore, we conducted a "constant water level permeability test" to measure the permeability coefficient. The result of the constant water level permeability test showed a measured value of 2.56×0.01 cm/sec. Thus, the required permeability coefficient for the sidewalk area in terms of "permeability" is a public standard value of 1.0×0.01 cm/sec. Our measured value exceeds this standard by more than double, proving that our permeable paving material sufficiently meets the required permeability performance for the sidewalk area. [Overview] ■ The permeability coefficient was measured in accordance with the "Soil Permeability Testing Method" based on JISA1218. - Constant water level permeability test: Applicable to soils with relatively high permeability coefficients (sand and gravel). - Variable water level permeability test: Applicable to soils with relatively low permeability coefficients (clay, silt, etc.). ◎ Exceeds the standard value and sufficiently meets the required permeability performance for the sidewalk area. *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.
