NTPC has developed geo-polymer aggregates from fly ash, which stands on statutory parameters of Indian standards. Aggregates are commonly used in civil engineering projects to stabilize terrain. The development will help in replacing natural aggregates, reducing the impact on environment.
The company’s research project on production of geo-polymer coarse aggregates from fly ash has met the statutory parameters of Indian standards and was confirmed by the National Council for Cement and Building Materials (NCCBM). The technical parameters as per Indian standards for its suitability to use in concrete works were tested by the NCCBM, Hyderabad and the results are in acceptable range. The development is the NTPC's R&D achievement in expanding the horizon in ash utilisation.
NTPC is the largest power utility company in India and has presence in Coal, Gas, Solar PV, Hydro and Wind Power Generation and Coal Mining.
