12 MM Jelly Stones: The Precision Aggregate

While 20 MM aggregates form the bulk of heavy concrete, 12 MM Jelly Stones are essential for creating a dense, smooth, and void-free concrete mix. They are particularly favored for reinforced structures with closely spaced steel bars, ensuring that the concrete flows into every corner of the formwork.

Key Product Features

• Cubical Shape: Our 12 MM aggregate is processed to maintain a cubical shape rather than flaky or elongated pieces. Cubical stones provide better interlocking properties, which significantly increases the compressive strength of the concrete.
• High Compressive Strength: Derived from hard igneous rocks like granite, these stones possess high crushing value and impact resistance, ensuring the longevity of the structure.
• Superior Bonding: The rough, crushed texture of the stone provides an excellent surface area for the cement paste to grip, creating a monolithic and powerful bond.
• Clean and Graduated: Our stones are screened to be free from dust, dirt, and organic matter. This purity ensures that the chemical reaction of the cement is not hindered, preventing future structural weaknesses.
• Low Water Absorption: With a very low porosity, these stones do not soak up the water intended for cement hydration, allowing for a precise and stable water-cement ratio.

Primary Applications

• Thin RCC Sections: Ideal for casting thin slabs, kitchen platforms, and lintels where the thickness of the concrete is limited.
• Densely Reinforced Members: Used in columns and beams with heavy steel reinforcement where larger 20 MM stones might get stuck (honeycombing).
• Pre-cast Concrete: The standard choice for manufacturing high-quality pavement blocks, designer tiles, and pre-cast compound walls.
• Roofing & Flooring: Often mixed with 20 MM stones (in a 60:40 or 70:30 ratio) to create a "well-graded" mix that fills all internal gaps, making the roof leak-proof.
• Bituminous Road Work: Used as a top layer in asphalt road construction to provide a smooth yet high-grip driving surface.
