Artificial Aggregates

Revolutionizing Construction: High-Performance, Low-Cost Artificial Aggregates

Our advanced artificial aggregates are engineered to be a superior alternative to natural aggregates. With a specific gravity of less than 1.8, they are significantly lighter, offering substantial benefits in modern construction. This lightweight property is crucial for enhancing the seismic resistance of buildings, improving thermal and sound insulation, and reducing the overall weight of concrete structures. By using our aggregates—which comprise up to 70% of concrete’s volume—the cross-sectional size of structural members can be minimized, leading to more efficient and flexible designs.

The Urgent Need for an Alternative

The global construction industry faces a critical challenge: the depletion of natural aggregate resources and the severe environmental damage caused by quarrying. This has created an urgent and growing demand for high-quality artificial aggregates.

  • Resource Scarcity: In many regions, natural aggregate sources are exhausted. Since 2001, Korea has relied on crushed stone as a substitute, with an annual demand of approximately 200 million cubic meters, while still depending on expensive imports for all structural lightweight aggregates.

  • Global Innovation: Leading countries have already shifted towards manufactured solutions. The United Kingdom began developing lightweight aggregates from clinker and blast furnace slag in the 1930s and now produces over 1.5 million tons annually using fly ash. The United States developed technology in 1994 to create lightweight aggregates by mixing fly ash and paper sludge. In Japan, Ube Industries successfully commercialized “Z-Sand,” an artificial aggregate made from coal fly ash.

A Clear Technological Advantage

Our innovative manufacturing process sets a new standard in the industry, overcoming the critical weaknesses of existing technologies.

FeatureConventional High-Temperature Technology
Our Advanced Low-Temperature Technology
Manufacturing ProcessRelies on a high-heat (1,200°C) sintering process in expensive, large-scale equipment like rotary kilns.
Cured at a low temperature (60-90°C), simplifying the process and eliminating the need for large, costly equipment.
Environmental ImpactGenerates excessive CO₂ emissions due to high energy consumption.
Produces 90% less CO₂, representing a massive leap forward in sustainable manufacturing.
Strength & PerformanceProduces weak aggregates (compressive strength of ~1 MPa) with a very low specific gravity, leading to material separation issues in concrete.
Delivers high-strength aggregates (20-50 MPa). Physical properties and particle size can be precisely controlled to meet diverse application needs.

Superior Economics and Performance

Our breakthrough isn’t just technological—it’s also financial. We deliver a higher quality product at a fraction of the cost, ensuring a superior return on investment.

Investment & Production

  • Conventional Method: Requires an investment of approximately 30 billion KRW to produce 200,000 tons annually.

  • Our Method: Achieves the same annual output of 200,000 tons with an investment of only 4 billion KRW.

Manufacturing Cost

  • Conventional Method: The energy-intensive sintering process results in a high unit price of ₩90,000 – ₩100,000 per m³.

  • Our Method: By eliminating the high-heat process, we can produce superior, high-strength aggregates for just ₩30,000 – ₩40,000 per m³.

Diverse Applications

Our technology transforms industrial byproducts, such as coal ash from power plants, into a range of valuable construction materials. The ability to customize the aggregate’s properties unlocks a wide variety of high-value applications.

  • High-Strength & Lightweight: Ideal for lightweight precast concrete, reducing costs and logistical complexity.

  • Lightweight & Insulating: Perfect for architectural insulating concrete.

  • Acoustic Properties: Excellent for sound-absorbing concrete used in urban infrastructure and sound barriers.
