In-House Laboratory

Batch-Wise Quality Testing

We crush our own bricks daily so that they never fail on your site. Here are the core tests every batch must pass before dispatch.

Compressive Strength Testing (CTM)

Each batch is rigorously tested on our digital Compression Testing Machine to ensure it meets the 7.5 to 12.5 MPa benchmarks.

Water Absorption Analysis

Bricks undergo a 24-hour submersion test. We mandate a strict < 12% water absorption rate, outperforming the IS limit of 15%.

Efflorescence (Salinity) Test

Bricks are placed in shallow water dishes for multiple days to verify zero salt leaching, ensuring paint longevity.

Dimensional Tolerance Check

Physical checks confirm exact ±1mm dimensional accuracy so contractors can save up to 25% on mortar joints and plaster.

Compliance

Bureau of Indian Standards Matrix

We strictly conform to the national engineering codes mandated for government and commercial infrastructure.

Contractor & Builder FAQ

Quality & Testing FAQs

Answers to technical questions from architects, civil engineers, and contractors in Bhopal.

How much do fly ash bricks cost in Bhopal, Mandideep and surrounding areas?

Direct factory rates start from ₹5.20 to ₹5.80 per piece depending on specification (Class 7.5 to Class 10), order volume, and destination site distance. Unlike local middleman brokers, our prices are direct factory ex-plant with transparent GST and tipper lorry delivery.

Why are fly ash bricks legally mandated for construction in Bhopal & MP?

Under Ministry of Environment, Forest & Climate Change (MoEFCC) regulations, all residential, commercial, and government construction projects within a 300 km radius of thermal power stations must use fly ash bricks to protect fertile agricultural topsoil and reduce carbon emissions.

How much cement mortar and plaster do fly ash bricks save compared to red clay bricks?

Fly ash bricks are machine-molded with steel dies giving precise ±1mm dimensional uniformity. Mortar joints are thin 10mm (vs 15-20mm for uneven red bricks), saving 25% masonry mortar. Additionally, smooth faces eliminate thick rough coats — plaster thickness drops from 20mm to 10mm, saving over 40-50% cement plaster.

How does compressive strength compare between fly ash bricks and red clay bricks?

Local kiln red clay bricks in Madhya Pradesh typically measure only 3.0 to 3.5 MPa with high breakage. RR Fly Ash Bricks are machine-compacted under 35+ tonnes hydraulic force and water-cured for 21 days, achieving certified strengths of 7.5 to 12.5 MPa (exceeding IS 12894:2002 standards).

Will fly ash bricks cause paint flaking or white chalk stains (efflorescence)?

No. Red clay bricks contain soluble alkaline salts that leach out with rain and cause white powdery efflorescence and peeling paint. Fly ash bricks are mineral-bound and inorganic with zero efflorescence, preserving wall paint and interior wall putty for decades.

What is your minimum order quantity and delivery turnaround time?

Minimum delivery quantity is one tractor trolley (approx. 2,500 bricks) or a full 6-wheeler / 10-wheeler tipper (4,000 to 6,000 bricks). We dispatch within 12 to 24 hours of confirmation across Bhopal, Mandideep, Kolar Road, Hoshangabad Road, Raisen, Sehore, and nearby sites.
