Applications
Why Ashtech
Consistency is a discipline. From power-plant collection to job-site delivery, every step is measured, documented, and engineered to remove variance from your build.
Batch-tested to BIS & ASTM specifications with mill certificates on every dispatch.
Long-term offtake agreements with 20+ thermal power plants ensure continuity.
Each tonne of fly-ash used displaces up to 0.9 tonnes of CO₂ from OPC.
Bulker fleet, rail rakes and coastal shipping for pan-India and export reach.
In-house NABL-accredited labs at every processing terminal.
Field engineers on-site for mix design, trials and value engineering.
Infrastructure




Beneficial extraction from thermal power stations.
Classification, drying, and quality upgrading.
NABL-accredited chemistry and physical testing.
Bulk, bagged & silo dispatch across the network.
On-site technical support at every project.
Global Presence
A network of processing terminals, warehousing partners and export corridors serving construction economies across four continents.

Sustainability
Our business is built on beneficial reuse — turning a coal-combustion residue into the world’s most valuable cement supplement. Every tonne dispatched is a tonne of virgin clinker not made.
Through fly-ash replacement in cement.
Diverted from landfill each year.
Waste stream converted to product.
Testimonials
“Ashtech has been our benchmark for fly-ash consistency across three metro corridors. Their engineers show up before we ask.”
