20 MM Jelly Stones: The Foundation of Strength
In a concrete mix, aggregates occupy nearly 70% of the volume. 20 MM Jelly Stones are the preferred choice for heavy-duty structural members because they provide the optimum surface area for cement bonding while ensuring the concrete remains dense and load-bearing.
Key Product Features
High Load-Bearing Capacity: Sourced from hard igneous rocks, our 20 MM stones have high crushing strength, making them capable of supporting the immense weight of multi-story buildings.
Excellent Interlocking: The angular nature of crushed stone ensures that the pieces lock together firmly within the concrete matrix, preventing internal movement and cracks.
Low Porosity: These stones do not absorb water, ensuring that the water-cement ratio of your concrete remains stable for maximum chemical strength.
Silt-Free Quality: Our aggregates are screened to ensure they are free from dust, clay, and organic impurities that can weaken the bond between cement and stone.
Primary Applications
General RCC Work: The standard size for casting foundations, footings, columns, beams, and slabs.
Industrial Flooring: Used in heavy-duty factory floors and warehouses that handle forklift and machinery loads.
Road Construction: Acts as the base and sub-base layer for highways and internal concrete roads.
Retaining Walls: Provides the mass and stability required for earth-retaining structures.
VSI vs. Non-VSI Aggregates: The Critical Difference
When sourcing jelly stones, you will often encounter two types: VSI (Vertical Shaft Impactor) and Non-VSI (Regular Crushed). The difference lies in the machinery used to crush the rock, which directly affects the shape of the stone.
1. VSI (Vertical Shaft Impactor) Aggregate
VSI machines use "rock-on-rock" or "rock-on-anvil" collision at very high speeds.
Shape: Produces cubical stones with rounded edges.
Quality: The high-speed impact breaks the stones along their natural grain, eliminating "flaky" or "elongated" pieces.
Performance: Because the stones are cubical, they flow better in a concrete mix (higher workability) and pack more densely, requiring slightly less cement paste to fill the gaps.
2. Non-VSI (Regular/Jaw Crushed) Aggregate
These are produced using traditional jaw or cone crushers that use compression to break the rock.
Shape: Produces more angular, flaky, or elongated pieces.
Quality: While strong, the presence of flat, thin stones can create "voids" in the concrete.
Performance: Flaky stones tend to break more easily under heavy pressure compared to cubical stones.
When to Choose Which?
Project Type
Recommended Type
Why?
High-Rise Columns & Slabs
VSI
Cubical stones ensure higher compressive strength and better flow in dense reinforcement.
Ready-Mix Concrete (RMC)
VSI
Essential for pumpable concrete; flaky stones can clog concrete pumps.
Foundations & Mass Concrete
Non-VSI
Cost-effective and perfectly suitable for massive pours where pumpability isn't a concern.
Internal Roads & Pavements
Non-VSI
Provides excellent interlocking for base layers at a lower price point.
Premium Residential Homes
VSI
Minimizes "honeycombing" and ensures the most durable concrete for your dream home.
