INTRODUCTION
India’s fly ash brick and block manufacturing sector has entered a phase of unprecedented technological advancement. The transition from manual and hydraulic presses to fully automated vibration–pressure systems has rewritten the operational and economic landscape of the industry.
At the forefront of this transition is Dongyue Technologies, whose German-standard engineering and advanced automation platforms have become synonymous with high-speed, high-strength, energy-efficient block production across India. By integrating global best practices with India-specific requirements, Dongyue Brick Machines have emerged as a preferred choice for manufacturers seeking scalability, quality consistency, and lower cost-per-brick.
The evolution from lime-based chemistry to cement-route formulations—paired with highfrequency vibration—has created a robust, reliable, and sustainable foundation for modern masonry production.
SECTION 1 — THE GREAT DEBATE: LIME VS. CEMENT ROUTE
Why Lime Lost the Race
Traditional FaL-G systems relied on fly ash, lime, and gypsum. However, the lime route faced persistent limitations:
- Inconsistent lime activity
- High moisture sensitivity
- 28-day curing cycles
- Difficulty in batching automation
- Dough-like mix requiring manual labour
Why Cement Became the Smart Choice
Cement-route production addressed these challenges with:
- ISI-certified quality consistency
- Rapid initial setting and 7-day curing
- 75% lower water consumption
- Complete compatibility with Dongyue automated batching systems
- Predictable strength performance and less maintenancet
SECTION 2 — TECHNOLOGY EVOLUTION: PRESSURE VS. VIBRATION
The Limitations of Pressure Moulding Earlier-generation hydraulic presses once dominated India but were limited by:
- Inability to use coarse aggregates
- Low M7.5–M12 strength range
- Poor plaster adhesion due to smooth surfaces
- High power consumption
- Restricted to basic brick formats
The Rise of Vibration Compaction
The industry’s major leap forward came with vibration technology—adopted and mastered by Dongyue Brick Machines. Their systems deliver:
- 65% lower power usage
- Dry-mix processing for clean, fast production
- Support for 4–6 mm aggregates
- Strength performance from M15 up to M45
- Compatibility with automated stackers and forklifts
o Fly ash bricks
o Hollow/solid concrete blocks
o Kerb stones
o Pavers
o Cavity blocks
Dongyue’s German-designed vibration platforms are known for higher frequency stability and minimal maintenance—leading to industryleading compaction and uniformity.
SECTION 3 — GERMAN BREAKTHROUGH: TRIPLE-ACTION COMPACTION
A technological revolution emerged through German-engineered triple-action machines— integrating:
- High-Frequency Vibration
For deep micro-particle rearrangement. - Vertical Pressure Compaction To eliminate voids and increase shape accuracy.
- Micro-Hammering Technology
To break surface tension and create superior bonding.
These innovations form the backbone of Dongyue’s German-Standard Block Machines, developed through long-standing collaboration with European technology providers.
Performance Outcomes
- Handling strength within 24 hours
- 30–40% cement savings
- Perfect edge detailing
- Uniform density across all products
- Multi-product capability through intelligent PLC programs.
SECTION 4 — AUTOMATION: THE HEART OF MODERN BRICK & BLOCK MANUFACTURING
Dongyue’s automation ecosystem brings a complete revolution to brick and block plants. Batching Automation (Dongyue Batching Systems)
- Precise cement, fly ash, and aggregate dosing
- Automatic moisture calibration
- Zero operator error
Block Forming Automation (Dongyue Brick Machines) - PLC-driven compaction cycles
- Recipe-based production for bricks, blocks,
and pavers - Consistent vibration and pressure patterns
Material Handling Automation - Automatic stackers designed by Dongyue
- Forklift-compatible pallet systems
- Up to 80% labour reduction in handling
Factory-Level Advantages - Higher production per shift
- Uniformity across batches
- Lower operating costs
- Minimal downtime
- Higher profitability
SECTION 5 — WHY CEMENT-ROUTE + VIBRATION DEFINES INDIA’S FUTURE
With Dongyue’s advanced vibration platforms and automated material handling systems, the cement-route model aligns perfectly with modern construction demands:
- Green and sustainable building materials
- Reduced water usage
- Faster project timelines
- Modular construction compliance
- Superior block strength and dimensional accuracy
- Lower production cost per unit
This combination is increasingly preferred by:
- Government agencies
- Infrastructure developers
- Smart City projects
- Architects and structural consultants
- Housing and commercial builders
CONCLUSION
India is entering a new era of scientific and highly automated masonry manufacturing. The shift from lime to cement, and from pressure moulding to vibration–pressure compaction, represents a structural evolution in the construction ecosystem.
Dongyue Technologies and Dongyue Brick Machines are playing a pivotal role in enabling this transformation, offering world-class Germanstandard engineering, scalable automation, and unmatched reliability.
With cement-route chemistry and triple-action vibration technology, the industry gains:
- Higher strength
- Faster curing
- Lower operating cost
- Improved sustainability
- Consistent quality
- Scalable automation
This is not simply technological advancement— it is the new foundation for India’s future-ready, automated, and eco- friendly construction sector
