I.R. Chemicals produces fly ash bricks in Kolkata, West Bengal, India using a mix of 60 - 70 percent fly ash, Portland cement, sand and water. The bricks are sized at 230 mm × 110 mm × 75 mm, which conforms to the dimensions specified in Indian standards for solid masonry units. The supplier states that the bricks meet relevant Indian standards and are certified by the laboratory department of Jadavpur University.
This composition typically delivers a compressive strength of 15 - 20 MPa and a water absorption rate under 8 percent, both of which are standard performance criteria for load‑bearing walls. The density of such bricks is usually around 1 700 kg/m³, providing a balance between structural capability and ease of handling. Their thermal conductivity is commonly about 0.55 W/mK, offering modest insulation benefits in building envelopes.
The bricks are suited to residential and affordable‑housing projects, as well as commercial structures where cost‑effective, eco‑friendly masonry is desired. I.R. Chemicals supplies the product in bulk, often on pallets that can be loaded directly into containers for overseas shipment. Prospective buyers should confirm the Incoterm, payment schedule and any required documentation with the supplier before confirming the order.

Fly Ash Bricks are an eco-friendly alternative to conventional clay bricks, manufactured using fly ash (a pozzolanic by-product of coal combustion), cement, and sand. These bricks comply with relevant Indian standards and offer high compressive strength with minimal water absorption, making them ideal for load-bearing and non-load-bearing wall construction. Widely sourced from South Asian manufacturers, fly ash bricks are increasingly traded globally as green building materials, favored in sustainable construction projects and affordable housing developments.

Importers should first request the full laboratory test report, including compressive strength, water absorption and pozzolanic activity, as well as a certificate of conformity to IS 2185. Verifying the exact brick dimensions and weight will help avoid mismatches during construction planning.
Shipments from I.R. Chemicals are usually dispatched from the Kolkata port or the nearby Haldia terminal. Buyers need to agree on the Incoterm (FOB, CIF or other), expected lead time and any advance payment requirements before confirming the purchase. Discuss freight options and container loading plans with the supplier to optimise logistics costs.
For quality assurance, arrange a third‑party inspection either at the manufacturing site or upon arrival at the destination port. Request documentation such as the Jadavpur University certification, BIS compliance certificate and a test report for each batch. These documents support customs clearance and verify that the bricks meet the specified technical standards.
