About the Product

WHAT IS
ASHCRETE FLY ASH?

Fly Ash is a fine, powdery by-product captured from the flue gases of coal-burning thermal power plants. It is a highly reactive pozzolanic material — meaning it reacts with calcium hydroxide released during cement hydration to form additional cementite compounds.

Ashcrete Fly Ash is carefully sourced, processed, and classified at our facilities to meet the exacting requirements of IS 3812 : Part 1 (India) and BS 3892 : Part 1 (UK/Export). Each lot is tested in our quality lab before dispatch.

Available in bulk tanker loads for RMC plants or bagged supply for smaller sites. We supply across Delhi NCR, pan-India, and export to Africa and the Middle East.

Why Choose Fly Ash

KEY BENEFITS

Ashcrete Fly Ash delivers technical, economic, and environmental advantages over plain OPC concrete.

Reduces OPC Consumption

Replace up to 35% cement, significantly cutting material costs without compromising strength.

Lower Heat of Hydration

Ideal for mass concrete — reduces thermal cracking in large pours like dams, rafts, and pile caps.

Improved Workability

Spherical particle shape acts as a lubricant, enhancing flow and reducing water demand.

Enhanced Durability

Reduced permeability and improved resistance to chloride ingress, sulphate attack, and alkali-silica reaction.

Long-Term Strength Gain

Pozzolanic reaction continues for months, often surpassing OPC concrete strength at 90 days.

Sustainable Choice

100% utilisation of industrial by-product — reduces landfill burden and CO₂ emissions per tonne of concrete.

Where It's Used

APPLICATIONS

Ashcrete Fly Ash is trusted across a wide range of construction types and infrastructure sectors.

🏗️

Ready Mix Concrete

Partial replacement of OPC in RMC plants for improved workability and reduced heat of hydration.

🌉

Bridges & Flyovers

Enhanced chloride resistance and long-term strength gain in prestressed and reinforced structures.

🛣️

Road & Highway Works

Used in pavement quality concrete and stabilised subgrade for improved durability.

🏢

High-Rise Buildings

Reduces water demand and improves pumpability in high-rise concrete pours.

🚇

Tunnels & Metro

Superior sulphate resistance and reduced permeability in underground structures.

🧱

Precast & Block Work

Fly ash bricks, blocks, pavers — lighter weight with equivalent or better compressive strength.

Common Questions

FREQUENTLY ASKED
QUESTIONS

Grade I (as per IS 3812) has finer particle size and lower loss on ignition (≤ 5%), making it suitable for structural concrete. Grade II is coarser and used in non-structural applications like bricks and fills.

Typically 20–35% of OPC by weight in structural concrete. For mass concrete applications (dams, thick rafts), replacement levels up to 50–60% are used with appropriate mix design.

Fly Ash concrete gains strength more slowly in early days (3–7 days), but typically matches and exceeds OPC concrete strength at 28–90 days due to the ongoing pozzolanic reaction.

When stored in dry, covered conditions (silos or covered sheds), fly ash has an indefinite shelf life. Exposure to moisture can cause hydration and reduce reactivity.

Yes — fly ash concrete shows significantly better chloride penetration resistance than plain OPC concrete, making it preferred for marine and coastal structures.
