About the Product

WHAT IS
ASHCRETE FLY ASH?

Ashcrete Fly Ash is a classified, high-quality Class F fly ash — a pozzolanic by-product of coal combustion in thermal power plants. It is collected dry from electrostatic precipitators (ESP) or bag filters and processed to meet strict quality standards.

Compliant with IS 3812 : Part 1 and BS 3892 : Part 1, Ashcrete Fly Ash is supplied by TSG Impex pan-India and exported to UAE, GCC, Middle East and Africa for use in ready-mix concrete, cement manufacturing, infrastructure projects, and precast production.

Why Choose This Product

KEY BENEFITS

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

🏗️

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

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.
