About TSG Impex

Two Decades of Sustainable Ash Excellence

TSG Impex India Pvt Ltd, headquartered in New Delhi, is one of India's pioneer industrial mineral and pozzolanic material processors. Over the past two and a half decades, we have recycled and supplied millions of tons of processed Fly Ash to national and international infrastructure giants.

Directly integrated with major thermal power stations including NTPC Dadri, NTPC Tanda, NTPC Meja, NTPC Unchahar, Renusagar, Bhusawal, Adani Mundra, Wanakbori, and Nabha Power, our automated grading and handling systems ensure strict batch-to-batch consistency for ready-mix concrete and cement manufacturers.

🔬 Continuous Lab Testing

Every consignment tested for fineness, loss on ignition, and silica activity index.

🚛 Rapid Logistics

Dedicated fleet of pneumatic bulkers and containerized export packaging.

Quality Assurance Guaranteed

We provide comprehensive NABL laboratory test certificates with every dispatch. Our products consistently exceed ASTM C-618 and IS-3812 specifications for compressive strength and workability.

Product Portfolio

High Performance Pozzolans & Minerals

Engineered mineral additives designed to increase concrete durability, reduce heat of hydration, and lower carbon footprint.

Top Seller

Ashcrete™ Fly Ash

Processed Class F / Class C Pozzolan

Premium processed pulverized fuel ash conforming to ASTM C-618 & IS-3812. Dramatically enhances concrete workability, long-term compressive strength, and resistance to chemical ingress.

Fineness (+45 Micron): < 15%
SiO₂ + Al₂O₃ + Fe₂O₃: > 70%
Loss on Ignition (LOI): < 2.0%

Lightweight

Cenosphere

Hollow Ceramic Microspheres

Inert, lightweight hollow ceramic spheres harvested from ash lagoons. Superior thermal insulation, high compressive resistance, and low bulk density for oil drilling and refractory ceramics.

Bulk Density: 0.35 – 0.48 g/cm³
Al₂O₃ Content: 28% – 36%
Hardness (Mohs): 5 – 6

High Strength

Star Silica™

Undensified & Densified Micro Silica

Ultra-fine amorphous silicon dioxide pozzolan. Fills micro-voids in concrete paste, creating ultra-high strength (M80–M120), impermeability, and extreme abrasion resistance.

SiO₂ Content: > 88% – 93%
Surface Area: 15 – 25 m²/g
Form: Densified / Undensified

High Reactivity

StarPozz™

High Reactivity Meta Kaolin (HRM)

Pure thermally activated aluminosilicate pozzolan derived from pure kaolin clay. Eliminates efflorescence, enhances architectural concrete brightness, and controls ASR.

Al₂O₃ + SiO₂: > 92%
Pozzolanic Reactivity: Extremely High
Color: Off-White Powder

Eco Cement

GGBS

Ground Granulated Blast Furnace Slag

Finely pulverized byproduct of iron manufacturing. Replaces 40% to 70% of Portland cement in massive concrete pours to eliminate thermal cracking and sulfate attacks.

Blaine Fineness: > 380 m²/kg
Glass Content: > 90%
Conformity: BSEN 15167 & IS 16714

Got Questions?

Frequently Asked Questions

Everything you need to know about our sourcing, logistics, and test certifications.

What is the difference between Class F and Class C fly ash? ▾

Class F fly ash is produced from burning anthracite or bituminous coal and contains less than 7% lime (CaO). It offers superior sulfate resistance and low heat of hydration. Class C fly ash is produced from lignite or sub-bituminous coal and has higher lime content with self-cementing properties.

What packaging options are available for delivery? ▾

We deliver in Pneumatic Bulk Tankers (25–40 Ton capacity) for direct silo discharge, 1.0 to 1.4 Ton Jumbo Bags (FIBC) with moisture liner for export/domestic, and standard 50kg HDPE/Paper Bags.

Do you provide manufacturer test certificates with every batch? ▾

Yes. Every bulker or shipment is dispatched with a comprehensive batch analysis certificate reporting physical fineness (+45 micron sieve), chemical composition (SiO₂, Al₂O₃, Fe₂O₃, CaO), LOI, and moisture content.

What is the minimum order quantity (MOQ)? ▾

For domestic bulk tanker delivery, the MOQ is 1 bulker (~25 to 35 Metric Tons). For bagged material and exports, the MOQ is 1 Twenty-Foot Container (FCL ~24 to 28 Tons).
