Dubai Gabro Stone: A Complete Technical Guide on Origin, Composition, and PSI
Meta Description:
Looking for the strongest construction aggregate? Learn everything about Dubai Gabro Stone (Black Stone). Discover its origin in Fujairah, chemical composition, 50,000+ PSI strength, and why it is the #1 choice for piling and high-rise projects in Bangladesh.
Introduction
In the world of civil engineering and mega-construction, the integrity of a structure depends entirely on the quality of its aggregates. While local stones serve general purposes, high-performance structures—such as skyscrapers, bridges, and deep foundations—require something superior. Enter Dubai Gabro Stone, often referred to as “Black Stone” or “Black Diamond” in the construction industry.
Known for its extreme density, low water absorption, and massive load-bearing capacity, Gabro stone is the gold standard for heavy construction. This guide explores the geological origin, chemical makeup, and technical specifications that make Dubai Gabro the undisputed king of aggregates.
1. What is Gabro Stone? (Geological Definition)
Gabbro is a coarse-grained, dark-colored, intrusive igneous rock. It is formed deep within the Earth’s crust when molten magma cools down slowly. This slow cooling process allows crystals to grow large, interlocking tightly to create a rock of immense hardness.
-
Color: Usually black or dark gray, sometimes with a greenish tinge due to mineral content.
-
Texture: Coarse-grained (Phaneritic).
-
Relation to Basalt: Gabro is chemically equivalent to Basalt. The difference is that Basalt cools quickly on the surface (fine-grained), while Gabro cools slowly underground (coarse-grained), making Gabro significantly stronger.
2. Origin: Where Does “Dubai Stone” Come From?
Although commonly called “Dubai Stone” in the market, the primary source of this high-grade aggregate is not Dubai city itself, but the mountainous regions of the United Arab Emirates (UAE).
-
The Hajar Mountains: The highest quality Gabro is mined from the Hajar Mountains, specifically in the emirates of Fujairah and Ras Al Khaimah.
-
Why this location matters: The geological history of this region has produced rock formations that are free from clay, silt, and organic impurities.
-
Import Process: Large boulders are blasted from the mountains, crushed into specific sizes (10mm, 20mm, Âľ inch), and shipped directly from the Port of Fujairah to international ports like Chittagong and Mongla.
3. Chemical and Mineral Composition
The strength of Dubai Gabro comes from its unique mineralogy. Unlike river stones which may contain weak particles, Gabro is a dense matrix of hard minerals.
Key Minerals:
-
Plagioclase Feldspar: Provides the structural framework.
-
Pyroxene (Augite): Gives the stone its black color and hardness.
-
Olivine: Adds to the density and specific gravity.
Chemical Resilience:
Gabro contains very low silica compared to granite, but is rich in Iron and Magnesium. This composition makes it highly resistant to chemical weathering and oxidation.
4. Technical Specifications & PSI (The Engineering Data)
For structural engineers, the data is the deciding factor. Below are the standard technical parameters of high-quality Dubai Gabro Stone available in the market.
| Technical Property | Standard Value | What It Means |
| Rock Compressive Strength | 35,000 – 50,000+ PSI | The stone itself can withstand immense crushing pressure. |
| Concrete Strength Potential | 5,000 – 10,000+ PSI | Ideal for producing Grade 40, 50, or 60 concrete. |
| Specific Gravity | 2.90 – 3.00 | It is much heavier and denser than local stone (2.60). |
| Water Absorption | < 0.50% | It is virtually waterproof, preventing dampness in buildings. |
| L.A. Abrasion Value | 10% – 15% | Highly resistant to wear and tear (Lower is better). |
| Bulk Density | 1,600 – 1,700 kg/m³ | Ensures compact and solid casting. |
5. Why Use Dubai Gabro Over Local Stone?
Is it worth the extra cost? Absolutely. Here is why engineers prefer it for critical projects:
A. Unmatched Load Capacity
For buildings taller than 10 stories or for deep piling, the foundation bears thousands of tons of weight. Local LC stones often crack under such high pressure. Gabro stone ensures the foundation remains solid.
B. 100% Salinity Free
Stones collected from riverbeds or coastal areas often contain salt. Salt is the enemy of construction because it rusts the internal steel (Rebar), causing the building to crumble from the inside. Mountain-mined Gabro is naturally salt-free.
C. Chemical Resistance
Gabro’s dense structure makes it resistant to sulfate attacks and carbonation, which are common causes of concrete degradation in humid climates like Bangladesh.
D. Zero Porosity
With water absorption below 0.5%, Gabro aggregates create a watertight concrete mix. This protects the steel reinforcement from moisture and ensures the building lasts 100+ years.
6. Ideal Applications
-
Deep Piling: For bridge foundations and high-rise basements.
-
Mega Infrastructure: Metro rails, flyovers, and expressways.
-
Ready-Mix Concrete: Essential for achieving high-strength concrete mixes (5000+ PSI).
-
Heavy Duty Floors: Factory and warehouse floors that support heavy machinery.
Understanding Dubai Limestone vs. Dubai Gabbro
While both are imported from the UAE and are considered premium aggregates, they possess distinct geological characteristics and applications.
Common Aggregate Sizes Supplied
We ensure the stone is meticulously crushed and graded to meet international standards (e.g., ASTM, BS) and local Bangladeshi project requirements.
Why Choose Imported Dubai Gabro for Your Project in Bangladesh?
For high-stakes projects that demand uncompromising quality, Dubai Gabro is the superior choice over many local and regional stones:
- Exceptional Compressive Strength: Gabro’s high density translates directly into maximum load-bearing capacity, essential for modern high-rise buildings and infrastructure projects in seismic zones.
- Durability: Its high resistance to abrasion and weathering ensures road surfaces and concrete structures last longer, minimising maintenance costs.
- Low Impurity and Absorption: Gabro is consistently low in flaky, elongated particles and deleterious materials, resulting in a cleaner, more chemically stable concrete mix.
