Indiana Construction Company has rapidly emerged as North India's largest and only professionally managed manufacturer of Ground Granulated Blast Furnace Slag (GGBFS) and Ultrafine GGBS. GGBS availability has historically been limited to the East, West and South — we changed that for North and Central India.
"To create greener, stronger and smarter infrastructure by providing world-class sustainable building materials that set new benchmarks in quality, performance and environmental responsibility."
But we believed one thing: concrete of the future will be sustainable. Today, that belief is becoming reality — and we are expanding to build North India's largest GGBS & Ultrafine GGBS manufacturing setup. Not just to grow, but to make high-performance green concrete accessible.

For decades, steel slag was discarded as industrial waste. Water quenching turns it into glassy granules; grinding turns those granules into a pozzolanic powder that can replace your cement.
Iron ore, coke and limestone are fed into steel furnaces operating at approximately 1,500°C.
Slag — a by-product — floats on top of the molten iron during the steel-making process.
The molten slag is rapidly cooled with water to form glassy granules, preserving its cementitious properties.
Granulated slag is ground in an advanced ball mill into a fine powder — high-quality GGBS, a superior cementitious material.
Packed in 50kg bags, jumbo bags and bulkers — ready to replace up to 70% of Ordinary Portland Cement with superior performance and dramatically lower carbon.
The result: a cementitious material that replaces up to 70% of Ordinary Portland Cement while delivering superior performance and dramatically lower carbon emissions.
The smarter shift: blended systems using GGBS & Ultrafine GGBS. The question is not whether to shift — it's how fast you adapt.
Ordinary Portland Cement alone means a heavy carbon footprint, higher heat of hydration and structures that age faster.

Both come from the same sustainable slag — the difference is in the grind. Ultrafine GGBS is micronized to a much finer particle size than normal GGBS, unlocking faster reactivity and a denser concrete microstructure.

Micronized fine particles — engineered for high-performance concrete where early strength and density are critical.
Finer particles react quicker in the mix.
Fills micro-voids for a denser matrix.
Faster demoulding and cycle times.
Lower permeability, longer life.

Micro Silica (silica fume) is an ultrafine material composed of amorphous silica particles with an average diameter of 0.15μm — 100 times smaller than cement particles. Through powerful pozzolanic reactions it forms additional calcium silicate hydrate (CSH) gel, dramatically enhancing concrete's mechanical properties and durability.

Infrastructure investment is rising from 5.3% to 6.5% of GDP by FY29, with cement demand growing 7–8% CAGR — and Micro Silica is essential for high-performance concrete in RMC applications.
Cement alone accounts for about 8% of global CO₂ emissions — together, cement and steel account for roughly 19%. Every metric ton of cement requires 1.5 MT of limestone, 0.22–0.25 MT of coal and 70–98 units of electricity — and emits 0.8–1 MT of CO₂.

Climate extremes and unpredictable weather patterns affecting infrastructure — visible in cities like Delhi every year.
Increasing greenhouse gas emissions from construction activities worldwide.
Rapid depletion of limestone, fossil fuels and sand — plus water pollution and heavy metals released into the air.
For every 1 MT of GGBS used instead of cement, approximately 0.8 MT of CO₂ is saved. Replacing even 50% of the world's cement with GGBS would transform the climate impact of construction — as nations pledge to cut carbon footprints for future generations.
For over a hundred years, steel slag was simply thrown away. Today we upcycle it into a material that outperforms the cement it replaces — a perfect example of the circular economy in action.
Industrial waste from steel-making becomes a high-value construction material.
~80% less water used vs. cement production processes.
